Dr. Cai is the recipient of two new research awards: 1) from the National Science Foundation (NSF) - Controls on Sea Surface pCO2 Variability and CO2 Uptake in the Western Arctic Ocean, and 2) from the National Oceanic and Atmospheric Administration (NOAA) - Synthesis of Ocean Carbon and Biogeochemical Data Collected During the Chinese Arctic Program Cruises. Both projects investigate climate-sensitive carbon cycling in the Western Arctic Ocean. |

Dr. Meile is the recipient of a new NSF award to study dissolved organic carbon (DOC) outwelling from salt marshes. Working with colleagues from Florida, Louisiana and Massachusetts at the Florida Big Bend, the export of DOC to the ocean will be quantified. As intertidal environments have declined rapidly over the past century because of human pressures, such estimates are critical for assessing the impact on coastal ocean productivity and global biogeochemical cycles, and to accurately evaluate the current and future goods and services of intertidal ecosystems. |

Drs. Joye, Samarkin and Meile received a new NSF award to study the degradation of offshore permafrost and methane hydrates on the Siberian Arctic Shelf. Together with scientists from the University of Alaska Fairbanks, they will elucidate the impact of global warming on methane dynamics. In particular, the current and potential capacity of sediments and permafrost to act as a methane source to the overlying water column and atmosphere will be determined. |

Dr. Meile, together with UGA Soil Scientist Dr. Thompson and isotope geochemist Dr. Scherer (U.Iowa) are the recipients of a new award from USDA to study iron cycling in soils. Quantifying the effect of changing frequency and amplitude of redox fluctuations in soils environments, the project will address how shifts in forms and speciation of iron affect processes of carbon sequestration/degradation and phosphorus availability, which is important for the long term soil fertility. |

A team of scientists led by Dr. Joye, including Dr. Samarkin and Dr. Meile, published a paper in Nature Geoscience (2, 349-354 (6 April 2009) doi:10.1038/ngeo475) on microbes that live within the plumbing of deep-sea mud volcanoes in the Gulf of Mexico, environments which support food chains independently of the Sun. Conducted in an area with quiescent brine pools and seafloor vents spewing mud, oil, brine and gases - conditions that may resemble those in extraterrestrial environments and early Earth - the study has shown that the microbial communities are unique to each extreme environment investigated.

Dr. Tish Yager will be hosting about 30 international scientists from Aug 30-Sept 3, for an NSF-supported Southern Ocean Data Workshop intended to bring together multi-disciplinary scientists working onboard the Icebreaker Oden during the past three field seasons in the Pacific sector of the Antarctica. They will be working on data synthesis and collaborative publications for a special journal issue. |

Dr. Yager is the recipient of two new NSF awards: 1) ASPIRE: Amundsen Sea Polynya International Research Expedition (ANT-0839069) and 2) Does competitions for nitrogen between autotrophs and heterotrophs control carbon fluxes in the western coastal Arctic? (ARC-0910252). Both projects investigate climate-sensitive microbial ecology and carbon cycling in polar oceans. |
