  • Study tracks ´memory´ of soil moisture

    Original story at MIT News The top 2 inches of topsoil on all of Earth’s landmasses contains an infinitesimal fraction of the planet’s water — less than one-thousandth of a percent. Yet because of its position at the interface between the land and the atmosphere, that tiny amount plays a crucial role in ...

  • Measuring global soil changes

    Global change is increasingly affecting important terrestrial ecosystem functions such as the filtering and buffering capacity of soils, the supply of clean water, soil fertility, and consequently, the production of food, feed, and fiber. Recent studies and reports from the United Nations indicate that water and soil resources are both heavily under pressure. Worldwide about 2 billion ha of land ...

  • Mapping Earth`s soil moisture with NASA

    Professor Dara Entekhabi from the Massachusetts Institute of Technology is to lead a science team designing a NASA satellite mission to collect global soil moisture measurements and other data seen as key to improving weather, flood and drought forecasts and predictions of agricultural productivity and climate change. At present, scientists have no network for gathering soil ...

  • NASA Satellite Set to Get the Dirt on Soil Moisture

    A new NASA satellite that will peer into the topmost layer of Earth's soils to measure the hidden waters that influence our weather and climate is in final preparations for a Jan. 29 dawn launch from California. The Soil Moisture Active Passive (SMAP) mission will take the pulse of a key measure of our water planet: how freshwater cycles over Earth's land surfaces in the form of soil moisture. ...

  • NASA Soil Moisture Radar Ends Operations, Mission Science Continues

    Mission managers for NASA's Soil Moisture Active Passive (SMAP) observatory have determined that its radar, one of the satellite's two science instruments, can no longer return data. However, the mission, which was launched in January to map global soil moisture and detect whether soils are frozen or thawed, continues to produce high-quality science measurements supporting SMAP's objectives with ...

  • Continuous moisture measurement of biomass for better energy content data

    Moisture content is one of the fundamental parameters when deciding on biomass fuel quality as this in turn dictates energy content and price. In short, water is expensive to transport and to remove. The traditional methods of determining moisture content and bulk density almost all involve random sampling from a consignment which is not without drawbacks. The Dutch company INADCO, exhibiting for ...

  • Method developed to measure solute movement in soils

    Scientists from Aarhus University and Aalborg University in Denmark have developed a new method for measuring the movement of solutes in intact soil. Improving on the existing method, the new procedure can be used on intact, undisturbed soil and provides more confident estimates. Movement, or diffusion, of solutes in soils is involved in many processes of agronomical, environmental and technical ...

  • Soil climate monitoring in Antarctica

    Antarctica, the coldest place on earth, has an area of about 14 million sq. km. About 98% of the continent is covered by ice, which averages about 2100 m thick. This vast ice sheet contains the earth’s largest fresh water reserve. Of the ice-free ground, only 0.3% is available for soils to form. Currently there are seven soil climate stations in Antarctica, which monitor a range of ambient ...

  • Restoring coastal wetlands? check the soil

    Rising sea levels and coastal development are threatening coastal freshwater wetlands with saltwater intrusion. While most ecosystem restoration projects have focused on surface water and groundwater, new research finds that conditions in the vadose zone, the unsaturated soil below the surface but above the water table, are of particular importance to seedling survival in coastal floodplain ...
