Highlights from the 2013 ASA, CSSA & SSSA Meetings in Tampa FL

November kicked off with the Soil, Crop and Agriculture Science Societies annual meetings, held this year in Tampa, FL, November 3-6. For those who were not able to attend, the focus of the meetings was Water, Food, Energy and Innovation for a Sustainable World. Six topical themes were covered: Sensing Innovation, Climate Change, the Food-Water-Soil Nexus, Sustainable Agricultural Systems, Improved Nutrient Management, and Energy, Soils, and Crops.

Eosense brings membrane technology to simplify soil gas efflux measurements

Did you know that soils produce 10 times more CO2 than all fossil fuel combustion? Surprisingly, it is true. Soil respiration produced 119.6 GigaTons of carbon per year during the 1990s, which far out paces the 6.4 GigaTons of carbon produced annually by the burning of fossil fuels in the same period (IPCC, 4th assessment, WG I, 2007, Figure 7.3).

A trip to Paris is never a bad thing...

A trip to Paris is never a bad thing, especially when the excuse is a gathering of about 50 of the top atmospheric scientists from around the world who are using water vapor isotopes. Last week, scientists from Laboratoire des Sciences du Climat et l'Environnement (LSCE) hosted an intimate workshop on “Advances In Observations, Models And Measurement Techniques Of Atmospheric Water Vapor Isotopes” at the Centre National de la Recherche Scientifique (CNRS) in Gif-sur-Yvette.

Methane Emissions Estimate from Airborne Measurements in Uintah Basin

A critical gap in determining the climate impact of the recent increase in US natural gas production is the lack of accurate and reliable estimates of associated emissions. In particular, the methodology used to account for fugitive methane (CH4) emissions during production is in question.

Field Tests of the Picarro G5101-i Analyzer

Gloria Jacobson, Picarro product manager for greenhouse gas analyzers, has been very busy lately. As the picture shows, she has been testing products in nearby marsh lands. In addition, she has discussed field tests with independent scientists, and attended several conferences in the U.S. and China. Over the next few weeks, she will be sharing her insights through a series of blog posts.

Water Isotopes Leave Fingerprints for Climate Scientists

The embedded video, produced by Marsha Walton and reported by Miles O'Brien, describes how University of Colorado meteorologist David Noone and his team are working to understand how water moves around the planet. According to the accompanying article, "The measurements are made using an optical measurement technology which has only recently become available, and which allows continuous in situ observations to be made on a practical basis.

Greenhouse gas highest since the Pliocene

An instrument near the summit of Mauna Loa in Hawaii has recorded a climate milestone: the amount of carbon dioxide in the atmosphere there has exceeded 400 parts per million (ppm) for the first time in 55 years of measurement—and probably more than 3 million years of Earth history.

Changes in Land-Use Impacts Water Balance in the Ecosystem

A recent article from Hydrological Processes examines groundwater recharge and water quality following changes in land use in an area of the Loess Plateau of China. Changes in land use, particularly transitions between grasslands and forests, have potentially large impacts on water balance and salt fluxes in the ecosystem.
