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.
The proposed research will document the circulation, variability, and driving mechanisms of the upper ocean in the “freshwater switchyard of the Arctic Ocean.” This unexplored reg

Maureen Raymo, a marine geologist and paleoceanographer whose name is connected with key theories about how ice ages wax and wane and how sea levels change, has been elected to the National Academy of Sciences, one of the highest honors awarded to engineers and scientists in the United States. She is the 11th current scientist from Columbia University’s Lamont-Doherty Earth Observatory invited to join the Academy for their excellence in original scientific work.
In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. Attention has focused on the West Coast, where the majority of the meltwater has been entering the ocean in recent years, but a new study from Lamont's Marco Tedesco suggests that a greater risk to global climate may actually be coming from the East.
A snapshot of the changing climate of the West Antarctica Peninsula, where the impact of fast-rising temperatures provides clues about future ecosystem changes elsewhere.
After less than a month in operation, a new NASA satellite has produced the first map showing how saltiness varies across the surface of the world’s oceans. Until now, salt measurements came only from ships, moorings and buoys floating at sea; NASA says its Aquarius satellite will capture in three years as much data as those earlier methods did in 125 years.
Stronger ocean currents beneath West Antarctica’s Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A growing cavity beneath the ice shelf has allowed more warm water to melt the ice, the researchers say—a process that feeds back into the ongoing rise in global sea levels. The glacier is currently sliding into the sea at a clip of four kilometers (2.5 miles) a year, while its ice shelf is melting at about 80 cubic kilometers a year - 50 percent faster than it was in the early 1990s - the paper estimates.
