This sludge is no slouch


Australian ingenuity is behind an innovative new cogeneration facility recently opened at a recycled water plant in Melbourne’s west.

This cogeneration facility produces enough renewable energy to power Western Water’s recycled water plant in Melbourne. Western Water.

Regional urban water corporation, Western Water, produces Class A recycled water from sewage at the Melton site. The new cogeneration facility will produce enough electric and thermal energy to drive the recycled water plant. Ozone-depleting methane emissions from sewage sludge treatment will be captured and burnt inside a microturbine to produce electricity. The cogeneration facility is connected to the site’s existing power grid, so that the 100 per cent renewable energy can power the plant. In addition, explains Western Water’s Managing Director, Mr John Wilkinson, an external heat exchanger installed alongside the microturbine will deliver heat energy for use in plant processes.

According to Mr Wilkinson, producing electricity from this renewable source will ‘reduce costs and cut carbon dioxide emissions by 1800 tonnes per year – equivalent annually to taking 420 cars off the road’.

The $2 million initiative was co-funded by the state government and Western Water, and built by Aquatec-Maxcon, an Australian water and wastewater engineering company.

Atlas to put ‘citizen apps’ on the menu


How can we better integrate data from the many disparate citizen science1 groups around the country to improve the nation’s biodiversity monitoring and research efforts? Coordinators at the Atlas of Living Australia project have been spending time with members of community environmental groups to identify the most effective features for a citizen scientists’ online ‘toolkit’.

The rapid development of web, map and mobile-based applications in recent years is making it easier for non-scientists to get access to scientific information and to record observations in the field – sometimes for later scientific use.

For example, Museum Victoria has just launched Biodiversity Snapshots, a new mobile application designed to help Year 3–10 school students and their teachers learn more about native wildlife.

The application includes a field guide with photos and sounds of each animal, and a way to record and upload observations on a mobile phone, netbook or tablet. When a student accesses Biodiversity Snapshots on a mobile device, the application presents information such as the animal’s name, shape, features, distribution, behaviour, habitat, sounds, status and ecology. It also lets students survey species found in school grounds, backyards, urban parks, bushland or coastal environments.

Biodiversity Snapshots is a collaboration between Museum Victoria, the Victorian Department of Education and Early Childhood Development, the Atlas of Living Australia and Earthwatch.

Gaia Resources, the consultancy that designed Biodiversity Snapshots, is also developing tools for citizen science groups to collect, organise and edit their data online through the Atlas of Living Australia website (see ECOS 153, p 24). The design process was kicked off earlier this year, with a series of workshops in which members of citizen science groups identified desirable features for an online toolkit. Not surprisingly, ‘easy to use’, ‘portable/mobile’, ‘fast’ and ‘free’ were at the top of their wish lists.

Harnessing the power of people



The combination of citizen science and new technology has produced some interesting projects. Recently, Einstein@home, an online citizen science astronomy project, described what are believed to be the first pulsars discovered through public participation. More than 250?000 volunteers helped Einstein@home to discover more than 100 potential pulsars.


Another international astronomy project, Galaxy Zoo, invited volunteers to judge from images whether galaxies were elliptical or spiral; and, if spiral, whether they were rotating in a clockwise or anti-clockwise direction.


By mid-2007, 80?000 volunteers had already classified more than 10 million images of galaxies. The final Galaxy Zoo datasets contain more than 34.6 million clicks by 82?931 volunteers: a demonstration of the power that citizen science can harness. According to a member of the Galaxy Zoo team, it would have taken researchers years to process the photographs without the volunteers.


Two other unusual initiatives are National Geographic’s archaeology project ‘Field Expedition: Mongolia’, and the San Francisco Neighborhood Parks Council’s ‘ParkScan’ website.


Volunteers in Field Expedition: Mongolia tag potential archaeological dig sites on GeoEye satellite images to assist explorers on the ground in Mongolia (see http://exploration.nationalgeographic.com).


The ParkScan website allows San Franciscans to monitor the condition of city parks and submit park observations directly to City staff (see www.parkscan.org).




The first beta public release of the Atlas of Living Australia website – which has been referred to as a biodiversity ‘yellow pages’– has been scheduled for late October 2010. The website will give researchers and the wider community access to Australian plant, animal and microorganism species’ names, photos, lists and distribution maps, mapping and identification tools, occurrence records, online literature, natural history collections and herbaria, and ecological, observational, and molecular data.

With data from museums, universities, CSIRO, herbaria and other biological collections linked together within a single web environment, users will be able to explore and analyse the information in new ways to develop a more detailed picture of Australia’s biodiversity.

‘The Atlas aims to enable any user to quickly locate and access information across the Internet on all aspects of Australian biodiversity,’ says the Director of the Atlas of Living Australia, Mr Donald Hobern.

For example, users will be able to use the Atlas’ mapping and spatial analysis tools to create a species list for a given area, or map the known occurrence for a species.

The Atlas – which is coordinated by CSIRO – will also give users open access to 50 years of archival material from the Australian Journal of Zoology (a contribution from CSIRO Publishing, which publishes ECOS).

From twitchers to storm chasers

People often ask whether citizen scientists contribute to ‘real’ science. With the right support and coordination, the answer is ‘yes’.

In 2009, for example, the North American Audubon Society analysed 40 years of data from its annual bird count, revealing dramatic shifts northward for winter bird populations as a result of warmer winters. This year's count will help scientists understand the impact of the Gulf oil spill on vulnerable species.

In this country, Birds Australia coordinated a continent-wide survey of birds from 1998–2002, in which thousands of members of the public participated – equipped with binoculars, field guides, GPS units and notebooks. These efforts culminated in the 2003 New Atlas of Australian Birds, presenting 4000 distribution maps for more than 650 bird species, including seasonal changes and breeding range.

Currently, more than 7000 volunteers continue to build Birds Australia’s database of seven million records of birds – the largest biological database in Australia, and one of the largest in the world. Apart from being used by qualified scientists in research projects, the data contributes to Australia’s ‘State of the Environment’ reporting.

Perhaps the best-known citizen science program in Australia has been the national network of more than 6000 volunteer ‘weather watchers’ coordinated by the Bureau of Meteorology. The volunteers record rainfall, spot storms, and observe river heights and conditions at sea for the Bureau’s weather databases.

Today, members of the public can join any number of citizen science groups, such as ClimateWatch, Frogwatch, Toadbusters, Waterwatch, Operation Spider, Seagrass Watch, Coastcare, Greening Australia, Carnaby's Black-Cockatoo Recovery Project, Conservation Volunteers, Shorebirds 2020 and the Threatened Bird Network.

Of course, an effective citizen science project requires effective volunteer training, technical support, data collection, coordination and encouragement. While data quality can be an issue, innovative tools for ensuring high-quality data are starting to come online. Data collected by volunteers may also need peer review or expert validation.
