McConnell Dowell, an Australian and International engineering, construction, building and maintenance company, is using Campbell Scientific data loggers and sensors within its new state-of-the-art weather monitoring and marine navigation system installed at Hay Point in North Queensland. The main purpose of the system is for Operations Health & Safety, ensuring safe working conditions for McConnell Dowell personnel. Campbell Scientific equipment being used in the system includes three CR800 data loggers, three RIMCO rain gauges, one CS475 radar sensor being used for wave height monitoring, and the Campbell Scientific CS110 and Strike Guard Lightning Warning system.

The lightning warning system provides early warning of the potential for lightning strikes by measuring the local vertical component of the atmospheric electric field at the earth’s surface. Combined with the Strike Guard optical-coincidence lightning sensor, which detects actual lightning strikes for up to 32 km from the installation site, a decision making algorithm provides early warning to site operators of the potential for lightning within the vicinity of the construction site. Integrated with the other measured parameters, the data is used to assist in decision making for Occupational Health & Safety.

McConnell Dowell now has the most unique weather monitoring system in Australia for its purpose. James Palmer from McConnell Dowell said ‘the system has been of great benefit and vital importance from a safety and commercial perspective, and the equipment is very specialised for the project we have undertaken.”

Work on interfacing the Campbell Scientific equipment into a complete turnkey solution for McConnell Dowell was undertaken by Marcom Watson, a Launceston based company specialising in Marine Electronics and Radio Communications and a recommended Campbell Scientific equipment integrator. Brett Victory, managing director of Marcom Watson, and their senior engineer Colin Kew, headed up the system installation in partnership with McConnell Dowell’s Radio Communications Marine Navigations and Weather Systems supervisor James Palmer. James said “Brett Victory and the Marcom Watson team have been fantastic. I could not have asked for a more experienced professional and trustworthy team to work with.” Dr David Hammond, Application Engineer at Campbell Scientific Australia, said “it was a pleasure working with Brett and the team at Marcom Watson in delivering state-of-art measurement systems they could interface into their custom-built weather monitoring system for McConnell Dowell. The quality of the final turn-key weather monitoring system provided by Marcom Watson is first class”.

The Secret Telstra Handshake

The NextG modem is sold without an airtime agreement. The user must arrange connection of the modem to a network and have it enabled for data use. The service provider will supply a Subscriber Identification Module (SIM), which plugs into the MM-6280IND and acts as a key to enable its use.

When setting up the account, the service provider may require some information such as the make and model of the modem being used. They will then set up an account and provide a phone number. This phone number is a voice number. However, voice is not supported in the MM- 6280IND, and it is not possible for the data logger to receive data calls (circuit switched data) and SMS with a voice number.

A data number is required for circuit switched data and SMS transmissions to the data logger. The service provider will need to know this information when setting up the account and enabling the SIM card. Furthermore, you will need to ensure that Code 2620 is activated on your account.

Code 2620 is Telstra’s code for data service on NextG. There are also options that can be specified to reduce complexity and cost of the service. You can strip all ancillary services such as Call Waiting, Call Diversion and Message Bank as these are not required.

If the unit is set up with a security code or pin number, it should be disabled before use with the Campbell Scientific data logger. The security code or pin number can be disabled by putting the SIM card into a normal digital mobile phone and select the security menu. Exact key presses will depend on the mobile phone used, but from this menu the PIN should be able to be disabled.

Monitoring Success - CSA officially Opens New Premises

The official opening of Campbell Scientific Australia’s new premises was held on Friday 30th March in Townsville, Australia. Approximately 40 dignitaries, customers, board members, invited guests and staff attended the function. We had customers travel from Brisbane, Canberra and Adelaide which was very pleasing in view of the long distances involved.

Above: Campbell Scientific Australia - New Premises - Front View

These exciting new premises are the culmination of 19 years of hard work and planning, with a good degree of the credit to go to Bert Tanner, a Director on CSA’s Board for most of that time.

Situated on a 6800m2 block, the former ten pin bowling alley building was ideally suited to CSA’s current and future needs. The large open plan frame was completely stripped and redesigned to provide purpose built premises. CSA currently occupies the rear half of the building and in the short to medium term, plan on sub leasing the front half. The approximate 1000m2 that we now occupy is double the area of our previous premises and will allow us to more than double our capacity before we will need to expand into the front half of the building. This move will then allow us to quadruple our current size and there will still be room for future expansion on the block if needed.

Above: Reception

Our Open Day comprised presentation sessions in the morning and afternoon, hands on product displays, and finished with a small celebration at the end of the day. Informative displays and demonstrations of many CS products, as well as an overview of some of our most recent case studies; including some spectacular pictures of applications on the Great Barrier Reef, were prepared for the event.

Above: The application engineers room - chatting with guests

Products on display included the CS data loggers and peripherals, the new IRGASON integrated gas analyser and sonic anemometer, the range of OBS water quality sensors, our latest family of discrete and composite water samplers, a visibility sensor developed by Campbell Scientific Limited in the UK, a new outdoor camera developed by Campbell Scientific Canada, the Hydrosense II developed here at CSA, various weather stations including the quick deploy FIREHAWK for fire fighting applications, as well a range of equipment suitable for Geotech applications such as the TDR systems we supply.

 Thanks to all customers and suppliers that were able to attend and to all CSA staff who put in an extra effort to make this a day to remember.

CSA Welcomes Apogee President Dr. Bruce Bugbee

Bruce Bugbee at Campbell Scientific Australia

This week we were very fortunate to have Dr. Bruce Bugbee, President and founder of Apogee Instruments visit us here in Townsville. A frequent visitor to Australia, Bruce is here to speak at the Australasian Controlled Environment Working Group (ACEWG) at Charles Sturt University in Wagga. Apart from his work at Apogee, Bruce is also Professor of Plants, Soils and Biometeorology at the Utah State University. This year he was awarded the Governor’s Science and Technology Medal for his accomplishments over a lifetime and in the short time he was here with us, it became clear why he is held in such esteem.

Campbell Scientific and Apogee Instruments have a close affiliation. Apart from being neighbours in Logan Utah, both companies have an over-arching mission to improve the process of measurement - pure and simple. We were delighted to be reminded by Bruce of our shared passion for the scientific process and the significance and potential impact of better measurements on the big issues of the day - most notably limited water resource, food production and creating a sustainable future.

We look forward to a continuing close relationship with Apogee Instruments and the refinement and development of measurement tools and technologies to address real-world problems.

Severe Weather Calls for New Flood Warning System

Inundation from flood waters is an annual occurrence for many living in Far North Queensland. For a remote community located an hour west of the Atherton tablelands, a rain event during a monsoon will often make it impossible for half the town’s population to get to the local pub for over a week, a severe event could have a much larger impact as the local water supply is sourced at a dam located upstream from the creek that runs through the middle of town. Significant rainfall could cause a quiet creek to become a raging torrent in just a short time.

Until recently, the community has only had the sound of running water and predicted water heights to make critical evacuation decisions. Implementation of a siren network and current conditions, display controlled by local disaster response teams makes use of incoming real time data from the dam spillway upstream. Warning SMS messages are transmitted to disaster management coordinators in extreme weather events.

The reality of severe weather events such as floods in south east Queensland in 2011 and category 5 Cyclone Yasi in North Queensland just a month later has prompted the installation of a flood warning system to protect the population from sudden inundation during a severe weather event. Real time data is measured at the dam spillway and provided to the evacuation planning centre to assist evacuation action plan procedures. A siren network throughout the town can be activated at a moment’s notice and SMS warning messages are sent to regional disaster management coordinators.

Measurements are taken at the Dam spillway by existing Campbell Scientific equipment. A CR1000 data logger takes water condition and depth readings from bubblers in the catchment and downstream from the dam over a V-notch flume. An RF450 spread spectrum radio network relays real time data through repeaters to external databases using a cell phone modem in a strong signal area, data also transmits to a CR800 data logger at the emergency planning centre. This CR800 is capable of controlling the siren network throughout town by analysing data and is connected to a PC running Campbell Scientific LoggerNet software with an RTMC user interface capable of displaying water levels and controlling siren functions.

The system will react to a severe weather event when flood waters exceed a critical predetermined upstream water level, this is communicated to the evacuation centre data logger. The system is capable of initiating the evacuation sirens automatically or manually by the evacuation coordinators using the RTMC interface in the evacuation centre. The availability of real time flood condition data provides a critical tool for evacuation coordinators and the siren network gives a reliable method of initiating evacuation procedures.

Coastal Water Quality Monitoring Network - Yantai-China

Yantai, China, is the pilot location for an innovative Coastal Water Quality monitoring network being jointly developed by Greenspan, Haicheng, the Chinese Academy of Science and the National Marine Agency.

Located on the Bohol Sea, the Yellow River basin is home to almost 350 million people. This large population, heavy industry and being one of the busiest seaports in the world all combine to potentially stress the natural environment.  Coupled with extensive mariculture and oil & gas reserves being explored in the sea, the potential for water quality problems are high.

Recognising the risks, proactive steps are being taken to monitor the water quality and detect any issues before the problems spread undetected.  Greenspan has delivered a water quality monitoring station that integrates a variety of water quality instruments into a real-time online system.

The station includes in-situ monitoring for:

Physical Parameters (YSI Sonde): 

• Temperature, Salinity, pH, Dissolved Oxygen, Turbidity

Nutrients (EnviroTech Instruments AutoLAB): 

• Nitrate, Ammonia, Phosphate using a wet chemistry analyser as Ion Selective Electrodes are ineffective in the marine environment

Biological Activity (YSI Sonde):

• Chlorophyll, Blue Green Algae

Pollutants (Turner Designs):

• Oil (Crude and Refined)

Traditionally, instruments performing these measurements require frequent maintenance, however the system uses an innovative multi-depth flow through sampling system that keeps the instruments protected on shore, dry in between measurements and in light proof chambers.  This solves the problems of bio-fouling, maintaining instruments without divers and obtaining measurements at multiple depths through the profile while minimizing hardware costs.  With the same instrument being used to measure water quality conditions at various depths, instrument variability has been eliminated, providing meaningful depth inter-comparison beyond the accuracy of most instruments.

Above: Crude oil reaction to rainfall event

In terms of the measurement system, the Campbell Scientific CR1000 provides all the measurement and control for full remote operation, including various modes such as:

• Low Temperature Shutdown.  The site can experience freezing conditions in the coastal waters so to protect the instruments the system is configured with a low temperature shutdown which stops water sampling, to be resumed only when the conditions warm up sufficiently

•  Manual mode.  All instruments can be run at higher sampling frequencies or in continuous recording to sample the water conditions during suspicious events
  
• Onboard instrument calibration.  The Nutrient analyser is equipped with reagents and standards for automatic calibration.  As both the instrument performance and the quality of the reagents/standards may change over time, automatic routines are used to run the standards through the system and use these to automatically correct the measured data for decay and drift.  The data logger is programmed with the routines for determining calibration coefficients for each parameter, in real time.

Above: Greenspan and Chinese Academy of Science staff checking the system performance

The CR1000 also manages the provision of data to various sources in real time – with a base station running Greenspan’s EnviroSCADA (with native Chinese support) and ENVAULT (www.envault.com.au) both receiving data in real time.  Aquatic Informatics Aquarius is also used to process the data for gaps, drift and other corrections before reporting to national agencies.

Above:Site inside hut with floating arm visible-Yantai Harbour

From the initial performance of the system, the benefits of the flow through system have been clearly demonstrated.  As shown by the photos below, there has been significant growth in the high nutrient and high light warmer waters near the surface, while the instrument inside the flow through system has no visible growth or degradation of the instrument condition.

Above: The intake arm with growth after 6 weeks

Above: The YSI before cleaning after the same period of time

The inter-comparison data between two nearby depths (in this case for blue green algae) also demonstrates the ability to detect small but discernible differences in the measurements beyond the accuracy of the instrument, even when the absolute value of the measurement is very small.

The Effect Of Lipids On Methane Emission

 Centre of Advanced Animal Science (CAAS), University of Queensland, Gatton Campus 

Methane chambers were constructed in climate control rooms within CAAS. There are two chambers within each of the two climate control rooms. Within each chamber are two steers housed in individual pens.  Methane emissions for each chamber are calculated using methane concentrations and airflow measurement within the supply and exhaust air ducts. Each duct is fitted with Debimo air flow measuring blades (Kimo®) and pressure transmitters CP200 (Kimo®). The datalogger acquires the airflow measurements from each of the six ducts every 15 minutes.  

Above: Each Chamber houses 2 steers

Data Logger - CR1000

Sensors & Peripherals - Debimo air flow measuring blades (Kimo®) are fitted in each of the six ducts (two supply and 4 exhaust).  Pressure transmitters CP200 (Kimo®) at each duct read in L/sec.  In terms of programming the supply ducts are 10V out = 2000L  while the exhaust ducts are 10V = 1000L.  Methane concentration within each duct is measured using an infra red technique (Columbus Instruments, Ohio, USA).  All equipment is in the plant room above the climate control rooms.

Above: Methane analyser and CR100

What parameters are being measured?

The parameters of interest are methane concentration and airflow within each duct.

Communications & Networking -  Data is retrieved on a laptop.  Programming was performed by Daniel Roebuck, Campbell Scientific

Project Description - This project focuses on the measurement of methane in Bos indicus cattle fed tropical pastures and supplemented with various lipids.  Methane is a digestive by-product from cattle and is a major greenhouse gas. Lipids can reduce methane emissions and are also a source of energy. Beef production systems in northern Australia use Bos indicus cattle grazed on subtropical pastures. These pastures generate high methane emissions and are seasonally of poor quality. The purpose of this project is to investigate the impact of lipids on the suppression of methane emissions and improvements in growth rate of cattle fed a diet of subtropical pasture. The lipids include algal meal, sunflower oil and whole cottonseed.   No research has been published with regard to methane emissions in cattle fed subtropical pastures supplemented with lipids. 

The 32 steers are supplemented for at least 50 days, food intake recorded daily and liveweight measured weekly.   Steers enter the chambers for four days (one day equilibration and three day emission measurement).

Above: Plant room ducts (above chambers)

This is a joint project with University of Queensland and DEEDI.  It is funded by MLA (meat and livestock association).  This project is headed by Assoc. Professor Athol Klieve. Karen Harper manages and runs this steer trial.

New Campbell Water Quality Samplers

We are pleased to announce that Campbell Scientific has acquired the Sirco line of water samplers from Southwell Corporation in Canada. Sirco samplers have a 30-year history of successful operation in storm-water, wastewater, and other water-quality applications. As stand-alone water samplers, these products already meet a variety of sampling needs. As we integrate them with our existing data-acquisition, telemetry, and sensor products, we will provide even more solutions for monitoring and control applications


Our search for a high-quality water sampler began a couple of years ago and it didn’t take long to find Sirco samplers. After distributing them for a while, we decided to make them a permanent addition to our product line as Campbell Scientific water samplers. The acquisition was finalized earlier this year, and we have successfully transferred the entire manufacturing operation to our headquarters in Logan, Utah.  We have been manufacturing samplers since late summer.

The future is bright for these samplers. They are already capable of being programmed on their keypad for time-based, pulse-induced, 4 to 20 mA-input, and flow-based samples. We plan to extend their usefulness even more by integrating them with rain gauges, turbidity probes, pressure transducers, and telemetry devices—on top of the power, logic, and communications protocols (e.g., Modbus, DNP3, TCP/IP) provided by our data loggers.

One of the biggest advantages of these samplers is that they use external vacuum pumps to draw water through intake tubing, instead of the traditional peristaltic pumps that induce flow by squeezing flexible tubing. Advantages of the vacuum-pump method include faster sampling rates, better vertical lifts, longer sampling distances, more-precise volume control between samples, and less maintenance. Because the vacuum method disturbs water samples less, they better represent the original water solution, especially if the solution has high concentrations of suspended solids. To prevent cross contamination, the samplers use air pressure (up to 28 psi) to purge the tubing of excess water.

 
The new product line includes many different options for both portable and stationary samplers. The PVS4150, PVS4120, and PVS4100 are portable, battery-operated water samplers. Designed for easy transport, the PVS4150 includes wheels, a telescoping handle, and a rugged case. The PVS4120 is the lightest sampler, weighing only 27 lb. The PVS4100 has a bigger pump that supports the fastest sampling rates, highest vertical lifts, and longest sampling distances. It also can use wider tubing (5/8-in. ID), which is better for handling large solids. All the portable models include space for ice to keep samples cool.

The CVS4200 and BVS4300 are stationary, ac-powered water samplers for wastewater applications. They use the same big pump as the PVS4100 and support all of its capabilities. The CVS4200 is an indoor sampler that has a corrosion-resistant steel enclosure. The BVS4300 is an outdoor sampler designed to handle extreme environments. It has a corrosion-resistant steel enclosure with a locking door and bolted-down instrument panel. All of the stationary samplers have a refrigerator option to keep the samples at the EPA-recommended temperature of 4ºC.  They can also be equipped with insulation, circulating fans, and heaters as needed.

Both composite and discrete options are available in both portable and stationary models. Composite samplers take samples, then deliver them into the same container each time. Discrete samplers collect samples and deliver them to different containers, from 500 ml to 1000 ml.
We are excited about the possibilities these samplers bring to water-quality applications.  Don’t hesitate to provide us with your input as we carry this great product line into the future.

Runoff Monitoring On Sugar Cane Farms

In December 2009, the Herbert Demonstration farm site was established in the Trebonne area on Orazio and Anthony Marino’s farm.  The project is supported by DEEDI, Terrain NRM, BSES and JCU staff.  Combining environmental sustainability and profitable farming as the key drivers, this is a collaborative effort between growers, government, research and industry bodies and is part of the Queensland and Australian Government’s Reef Plan to improve water quality entering the Great Barrier Reef lagoon. There are Demonstration farm sites also located in the Burdekin and Tully areas.

The Herbert Demonstration farm site has been divided into 2 sections- one section planted on a 1.6m conventional farming system and one section planted on a 1.83m controlled traffic  mound planted farming system. To date there has been 6 additional cultivations in the conventional farming system block compared to the controlled traffic mound planted block, which has attributed to a higher cost of establishment in the conventional block.  All nutrient applications to date have been identical and are based on the BSES 6 Easy Steps guidelines and in accordance with government regulations.

In the fallow period  a legume was grown on both blocks, the  legume mulched. The  controlled traffic mound planted block  was zonal tilled and the conventional block was conventionally and prepared. It is important to understand the fate of legume nitrogen under different farming practices; consequently the movement of nitrogen in the soil profile from the legume crop is being investigated for both treatments over a 12 month period.

The block has been soil mapped using electro-magnetic soils mapping equipment and ground truthed. This equipment identified 5 distinctive soil types within the block and found areas of sodic soil not previously known. Within the 5 soil types, soil sampling to depths of 1m have occurred. It was found that 2 of the 5 soil types had low levels of phosphorus (P) present; below the government guidelines for P application. To date no P applications have occurred within the block because a routine soil test taken across the block indicated that no P fertiliser applications were required.

Water sampling for nitrogen, phosphorus and pesticides have occurred on the site since September, 2010. Water runoff from a number of rows in each treatment are diverted through a calibrated flume: as highlighted in the photo opposite.  Sensors and monitoring equipment collect a water sample automatically every time a certain volume of runoff passes  from the field and through the flume. The collected water samples are then sent to labs at James Cook University and Brisbane for analysis.

The cost effectiveness of the various “new” farming system practices will be assessed on the controlled traffic mound planted block and compared to the conventional block. Adopting a new farming system can bring significant capital expense. Through rigours monitoring, the Herbert demonstration farm project will assist industry gain a better understanding of the environmental, economic and social benefits of implementing new farming practices. 

The site will be continued to be monitored over the next 2 years. Trial results will be made available to industry as they become available.

Tough Turf Times Require Innovative Technology to Survive

In the past few years, Melbourne councils have been required to reduce water allocations to less than 25% of previous water restrictions or to limit irrigating to one in four turf sporting grounds under strict Stage 3a restrictions. After substantial rainfall in the catchment areas, many restrictions have been eased to Stage 2 but monitoring and reporting of irrigation data for sustainable management is now considered best practise regardless. Water scarcity and waste minimisation are issues that are here to stay and councils must be seen to be decreasing water consumption in their facilities. Ground managers and curators need to adopt new initiatives to minimise irrigation waste and optimise precious resources.

The Victorian Government has recently provided $2 million worth of funding under the Sustainable Sporting Grounds Program to help sports clubs deal with the impact of increasingly stringent restrictions and future proof facilities against drought conditions.

The Minister for Sports and Recreation Hugh Delahunty says  "This program provides the cash boost needed for sports clubs to develop long term, sustainable, low water use community sporting facilities that are better equipped to deal with future climate challenges.”

Traditionally, councils have simply maintained sporting grounds to the basic standards required by sporting codes. When new restrictions were implemented, one in four playing fields were left to survive on rainfall unless the club or local council could justify having additional water provisions.

Many fields deteriorated under severe restrictions and became unplayable while demand continued to rise for these facilities. Restrictions also led to less competitive or socially disadvantaged users having less access to suitable playing fields. Increased population growth and demand for playing spaces in general have placed additional pressure on those turf based facilities that meet the criteria to benefit from an increase water allocation.

Introduced in April 2007 in metropolitan Melbourne, the policy aimed to achieve an 80% reduction in water use on sports grounds. To qualify for further water allocations, facilities need to develop a ‘Water Conservation Plan’, install water meters, centralise watering systems, audit irrigation systems and publish irrigation schedules. There was a fear that these seemingly harsh restrictions would ultimately lead to increased player injury, undermine community engagement, reduce the health and well-being in the population, and even lead to job losses in the turf industry. Councils were therefore faced with the challenge of utilising limited state and federal funding to optimise limited water allocations.

The impact of water restrictions on playing fields varies greatly depending on the local rainfall, soil types, ground conditions and intensity of activity. The need to know the soil moisture content in a variety of soils and conditions is paramount.

One way to reduce your water footprint is to stop over-watering.  Not only is it environmentally more sustainable, it will save money and produce better turf.

Many councils across Australia have invested in the Hydrosense soil moisture monitoring system made by Campbell Scientific to ascertain optimal water coverage and duration. With a release set for September this year, the Hydrosense II is the second generation of this innovative Australian technology.


The Hydrosense II is a handheld display and soil moisture sensor. Featuring a new display and a new easy insertion soil probe, this compact measurement system has a clear, large LCD display with a convenient layout of the buttons to allow for undemanding one-handed operation in the field.

Incorporating Bluetooth connectivity with an onboard GPS, the new and improved Hydrosense II allows for storable geo-tags recording location specific data. This data can be transmitted wirelessly from your handset to your laptop or PC and can then be exported to Google Earth, GPX and CSV (Excel).


Full spacial representation can be achieved allowing gardeners, curators and grounds keepers to selectively irrigate only where and when needed, reducing water costs, improving sustainability and the overall condition of the turf.

According to a report commissioned by the Victorian Government on ‘Ground Conditions and Injury Risk’, the Hydrosense is “easy to use, not subject to operator error”. The new Hydrosense II, which sells from around $1500, also offers the latest communication capabilities coupled with geo-tagging for more precise, three dimensional representation of your playing field and Campbell’s legendary technical and integration support.

 The Hydrosense II is recommended for any curator or grounds keeper wishing to comply with sustainability programs while getting maximum mileage from your allocated resource.

Up to $100,000 is available for each project. Applications close Wednesday 10 August 2011.

University of PNG AWS Tender Won by Joint Australian/UK Campbell Scientific Bid

In 2010, the University of Papua New Guinea purchased an automatic weather station from CSA for evaluation. The system had to be web enabled, capable of handling the extreme tropical conditions of PNG and have adequate battery and solar power to remain online for extended periods in tropical monsoonal periods. Despite these challenges, CSA’s engineers and production team provided a system that passed the University’s requirements with flying colours.

In early 2011, the University of PNG applied for and secured external funding for 18 automatic weather stations based on the specifications of the unit previously supplied by CSA. The only problem was that the funding was provided by the European Economic Community (EEC) and their strict requirements required that the 18 stations be supplied by a company from a country within the EEC – which ruled Australia out.

Our sister company in the UK, Campbell Scientific Ltd, quickly agreed to manufacture and supply the 18 stations based on CSA’s specifications with some additional regional components being supplied by CSA. The stations have now been shipped to the University of PNG within budget and on time – another joint Campbell Scientific success story.

Charles Sturt Uni Rhizolysimeter Project

The new Charles Sturt University (CSU) Rhizolysimeter is the largest root-growth research facility in the world. The complex contains 72 intact soil monoliths encased in steel tubes. The encased soil monoliths are arranged in rows of 18 in two underground rhizolysimeter laboratories (2 rows in each lab) that allow access to the side of the soil cores beneath the soil surface. The design of the facility allows for nondestructive, in situ, and high temporal resolution measurements of integrative root growth and soil water dynamics. The soil monoliths can be fitted with a wide range of sensors. Campbell Scientific Australia are installing a total of 576 TDR (Time Domain Reflectometer) sensors, 8 in each soil monolith. The CS610 3-rod TDR sensors are connected to a network of multiplexers controlled by a CR1000 data logger.

Environmental Management Increases Mining Profits

Conventional wisdom places environmental practices as an obstacle and burden to mining operations – an obstruction to the actual running of a business. Nothing could be further from the truth. For a savvy mining operator, an environmental management plan can be a highly useful tool for maximising profit margins, minimising potential liabilities, increasing efficiency and gaining positive publicity.

An Environmental Management System (EMS) in Australia means implementing an international standard of consistent improvement – namely, ISO 14001. A company which complies with ISO14001 in a given review period will be issued a certificate to that end and will enjoy greater relations with other ISO14001 compliant companies. Having a compliant EMS also serves as significant protection from legal issues, often preventing costly and image-damaging litigation.

ISO 14001 is not designed to dictate to Managers how to run their companies; it is a tool for improving efficiency of business systems and environmental performance. Having an EMS can be a competitive advantage in the tender process, leading to increased tender success and increased business success. Having a certified EMS is a requirement to entering some Japanese or EU markets.

Environmental risk categorisation and rating is a part of a successful EMS, improving your organisation’s ability to manage and mitigate risk associated with the environmental effects of mining operations and their after-effects. Recycling waste and reusing energy is also a key part of an EMS, allowing organisations to reduce operating costs, increasing profit margins. For example, following the Queensland floods earlier this year, water produced as a result of coal seam gas extraction was allowed to be used for removal of mud and debris from flood-affected buildings given that the water quality passed suitable criteria. This produced goodwill and positive publicity for the participating companies, possibly increasing public support for further mine development.

The essence of the ISO14001 standard is that it is a positive feedback loop – to maintain their certificate, a company must improve its environmental management measurably every year. One method of doing this is to introduce automated data logging of important environmental variables, such as the salinity of runoff, or the suspended solids in tailings dams. Automatically logged data can be used to construct much more detailed models than manually collected data, as it can be collected more frequently with ease. Another advantage is that automated collection allows real-time monitoring of on-site conditions, without waiting weeks for lab analysis of samples.

Campbell Scientific Australia is based in Townsville, Queensland and has been a leader in water quality measurement for 18 years, with hundreds of sites across Australia boasting Campbell sensors and data loggers. The company offers automated, on-site logging of water quality data including turbidity, suspended solids concentrations, water temperature, water depth, electrical conductivity, salinity, pH, oxygen reduction potential and dissolved oxygen.

Dissolved solids concentrations are especially important for water quality in an EMS, as standards are set for the suitable use for water in tailings dams etc and often have a maximum allowable suspended solids specification for a given application. For example, the flood water cleanup mentioned earlier allowed CSG water which met criteria of pH, suspended solids and electrical conductivity (often used as a measure of salinity) to be used for that purpose. Different requirements must be met to allow waste water to be used for dust suppression or for revegetation. Campbell Scientific Australia can provide real time monitoring of these criteria, allowing business decisions to be made quickly with instant and historical data available easily. A simple system for a small tailings dam might cost approximately $25000, a negligible cost compared to the overall cost of running a mine.

Real time data logging of water quality is a vital component of an EMS for mining companies and Campbell Scientific Australia’s Application Engineers have the expertise and flexibility to make the integration and support of on-site sensors a successful and profitable project.

Back on Line After Cyclone Yasi

A Big Hello To Our Customers!

We apologize for the fact that the offices of CSA could not be contacted for the last week.

As you may or may not be aware, one of the largest cyclones ever to hit the Australian coastline crossed around 200 klm north of Townsville last Wednesday night.

Cyclone Yasi did massive damage to the coastal towns of Mission Beach, Cardwell and to the sugar town of Tully.

The city of Townsville was not in the eye of the cyclone where the winds are strongest but according to the media, we were hit by category two winds of between 125kph to 170 kph.
While there was little structural damage to buildings in the city, there was considerable damage to signs, trees, power lines and transformers.

Shortly after the cyclone, only 15% of the city of Townsville had power.

The offices of CSA were in one of the worst affected areas and power was only restored late yesterday afternoon – almost a week after the cyclone hit.

So please bear with us while we catch up on the support calls, emails and shipping that has accumulated over that period. We will do our very best to respond in a timely manner.

The last few months has seen a variety of intense weather patterns throughout Australia.

With floods in central and southern Queensland and Victoria, bushfires in Western Australia and extreme heat in South Australia, Victoria and New South Wales, the people of Australia have suffered many trials and tribulations.

We at CSA are extremely proud of the instrumental role that Campbell Scientific equipment and staff have played in monitoring these events and in many cases, minimizing the loss of life and property.

With the help of you, our loyal customers, we hope that we can continue to provide such service and support to the Australian community.

Regards,

The Team at CSA

EC Systems - Report from Dave in Sarawak

Hi Dudes, both stations installed and now having a break for a day. Amazing place and friendly people. They have been introducing us to their unique food , water chicken (frog), flying fox (yes the bat), wild boar, goat mud crab, and fish in many different ways washed down with bucket loads of Heineken. It’s all been great, even the bat. The first station went up without a hitch apart from a minor glitch with the net radiometer. The second station was a 1.5 km walk through knee deep peat sludge. Once up the tower a local swarm of honey bees came to visit us at the 10 metre level. I was working with about 100-200 bees sitting on my shirt drinking the sweat out of it. Occasionally they would get inside the shirt and that’s when I was stung (6 time in all). The 2nd tower is functioning - the shorter SDM cable worked a treat. Dave.
