Dr. Patricia Yager in collaboration with Mark R. Dennett (Woods Hole Oceanographic Institution) and Walker Smith (Virginia Institute of Marine Science) has been awarded a grant from the National Science Foundation to study 'Controls on climate active gases by Amundsen Sea ice biota'. This project includes a 6-7 week cruise from Montevideo to McMurdo, Antarctica and provides an opportunity to study 3000 miles of ice-covered waters and their impact on climate sensitive biogeochemistry. |

Dr. Patricia Yager and colleagues show that the Amazon River plays an important role in delivering nutrients to the ocean and thus enhancing primary productivity in the ocean. This new production then results in a net sinking of carbon fixed by diazotrophs in the river plume and thus sequesters 0.6 Tmol of C per year. These findings are published in the Proceedings of the National Academy of Sciences (http://www.pnas.org/content/105/30/10460) and show that tropical rivers can be a significant transport of atmospheric carbon to the deep ocean.

Versatile
Bacteria in the Coastal Ocean
Research led by scientists
in the Department of Marine Sciences and published in the
journal Nature shows that the roles played by coastal bacteria
in carbon cycling aren’t nearly as specific as previously
suspected. Their work reveals how various genes important
in the marine carbon cycle are packaged together into bacterial
cells, and help efforts to predict how those genes will
be affected in a changing ocean. For more information see
the article by Dr. Xiaozhen Mou, Shulei Sun, Dr.
Robert Hodson, and Dr.
Mary Ann Moran at: http://www.nature.com/nature/journal/vaop/ncurrent/full/

Dr.
Burd will be returning to Antarctica to help teach the
2008 NSF International Graduate Training Course in Antarctic
Biology. This course is sponsored by the US National Science
Foundation and allows the students to gain experience working
in Antarctica and to learn about the issues and problems
of conducting research in such an extreme environment. A
web-log following the progress of the course can be found
