  • Ocean salinities show an intensified water cycle

    The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases. The study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, shows the surface ocean beneath rainfall-dominated regions has freshened, whereas ocean regions dominated by evaporation are saltier. The paper also confirms that surface warming of the ...

  • New Discoveries Improve Climate Models

    New discoveries on how underwater ridges impact the ocean's circulation system will help improve climate projections. An underwater ridge can trap the flow of cold, dense water at the bottom of the ocean. Without the ridge, deepwater can flow freely and speed up the ocean circulation pattern, which generally increases the flow of warm surface water. Warm water on the ocean's ...

  • Innovating business models for sustainability

    How innovation in products, processes and business models can help organisations become more sustainable. By Richard Waters, Principal, Carbon Trust Advisory. Regulation, cost, reputation, revenue and risk management are driving many organisations to cut their carbon emissions, and become more sustainable. More businesses are looking at how they can put environmental sustainability at the heart ...

  • Calculating ‘old’ and ‘new’ water runoff

    Just ahead of a rainstorm, Cody Ross might run out to an agricultural research site as part of his graduate work. He’ll need to get some dye into an injection well. The point? To evaluate the path that water follows from the field during and after the rainstorm. Ross, a member of the Watershed Systems Research Program at the University of Manitoba, is measuring water flow in a part of ...

  • Measuring forestry`s impact on water availability

    Undertaken by a team of CSIRO Water for a Healthy Country Flagship scientists for the National Water Commission (NWC) and Forest & Wood Products Australia, the project developed modelling tools to provide greater confidence in estimating the impact of new plantations on catchment stream flow. Australia's blueprint for water reform – the National Water Initiative (NWI) – recognises ...

  • Using vegetated filter strips to improve water quality

    Microbial contamination of surface water resources is a critical water quality issue, leading to many documented health and environmental concerns. Vegetated filter strips have become an important component of water quality improvement by reducing sediment and nutrient transport to surface water. Although this management practice is also beneficial for controlling manure-borne pathogen transport ...

  • Featured Product: Evaluating the Source of Water to Wells Using Metamodeling

    Numerical groundwater modeling is a strength of the USGS, from software development (likeMODFLOW) to applications, such as the regional groundwater availability studies highlighted in the December 2015 News and Highlights. Numerical models ...

  • Nanotechnology for clean water: Facts and figures

    Nanotechnology could help give millions clean drinking water. David J. Grimshaw outlines the potential, the progress and some of the risks. Technology has long been important in providing clean drinking water and irrigation for food crops. Indeed, people have had water technology for thousands of years — the Romans were using aqueducts as conduits for drinking wateraround 300BC. But making ...

  • Groundwater footprint reveals unsustainable water consumption

    Reservoirs of water stored under the earth’s surface, otherwise known as groundwater, are a valuable resource. However, using a footprinting method, a new global study has indicated that about 1.7 billion people live in areas where groundwater is being used more quickly than it can be replenished. Groundwater supplies water to billions of people and is important for agricultural ...

  • Stratospheric water vapor is a global warming wild card

    A 10 percent drop in water vapor ten miles above Earth’s surface has had a big impact on global warming, say researchers in a study published online January 28 in the journal Science. The findings might help explain why global surface temperatures have not risen as fast in the last ten years as they did in the 1980s and 1990s. Observations from satellites and balloons show that stratospheric ...

  • Comparing water pricing policies for a case study in Greece

    A case study in Greece suggests that farmers growing low-value crops such as maize and cotton will suffer most from policies which introduce charges for water. However, this impact can be mitigated if groundwater is priced based on the energy needed for pumping, shifting some of the burden to higher value crops. As global warming progresses, water scarcity has become an increasing concern. ...

  • First images from ESA’s water mission

    In less than four months since launch, the first calibrated images are being delivered by ESA’s SMOS mission. These images of 'brightness temperature' translate into clear information on global variations of soil moisture and ocean salinity to advance our understanding of the water cycle.  Launched on 2 November, the Soil Moisture and Ocean Salinity (SMOS) mission is improving our ...

  • MOE presents: provincial water monitoring networks

    Dave Rudolph – "Emerging Needs for Temporal and Spatial Data Precision" Dave Rudolph, with the University of Waterloo, started the symposium off with a very thought provoking presentation on the value of data. Dave used case studies to illustrate how different factors impact the quantity and quality of water resources, and how a small change can affect these conditions quickly and ...

  • Integrated water management helps control agricultural pollution

    By 2015, all surface waters and groundwaters in the European Union should aim to achieve 'good status', with healthy ecosystems and low levels of pollution. The goals for the management of these bodies of water are set out under the Water Framework Directive1. Recent research suggests that integrated management of water catchment areas could be used to control sources of pollution within river ...

  • Waters acidified by air pollution have recovered as predicted

    Back in 1999, a group of scientists predicted how changing air pollution levels would affect the acidity of lakes and rivers in Europe in 2010 using a computer model. A follow up study has now gathered actual measurements of these waters to see if the predictions came true. The observations show that most of the rivers and lakes did recover from acidification, as forecast by the model, and ...
