O. Roger Anderson is a microbiologist at Lamont-Doherty Earth Observatory who studies bacteria, amoebas, fungi and other microorganisms. Lately he has been thinking about how tiny organisms that inhabit the vast northern tundra regions could contribute to changing climate, since, like humans, they breathe in oxygen and breathe out carbon dioxide.
This page contains information on the research activities in R. Sambrotto's Lab. at Lamont-Doherty. Its covers the people involved and the analytical work we do on the biogeochemistry of oceans and estuaries. It includes the analytical capabilities available to outside users as well as information and protocols for people working in the lab.
In this annual fall event school groups all along the Hudson River estuary go down to the river's edge to collect scientific information and share it to creat
A detailed (ca. 100 yr resolution) and well-dated (31 AMS 14C dates to 24 cal.

The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions...
