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.
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.

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.
