A growing "dead zone" in the middle of the Arabian Sea has allowed plankton uniquely suited to low-oxygen water to take over the base of the food chain. Their rise to dominance over the last decade could be disastrous for the predator fish that sustain 120 million people living on the sea’s edge.
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.

Smaller than a speck of dust, Emiliania huxleyi plays an outsized role in the world’s seas. Ranging from the polar oceans to the tropics, these free-floating photosynthetic algae remove carbon dioxide from the air, help supply the oxygen that we breathe, and form the base of marine food chains. When they proliferate, their massive turquoise blooms are visible from space.Now scientists have discovered one of the keys to E. huxleyi’s success. A seven-year effort by 75 researchers from 12 countries to map its genome has revealed a set of core genes that mix and match with a set of variable genes that likely allows E. huxleyi, orEhux, to adapt to different environments. Their results are described in the latest issue of Nature.

A city effort to clean up polluted Newtown Creek by aerating the water to boost oxygen levels is having an unintended effect: it is releasing sewage bacteria and other particles into the air above the site, researchers say in a new study in the journal Environmental Science and Technology. The researchers found bacteria types in the air consistent with the sewage and oil pollution in the creek. The study is one of the first to establish a link between water pollution and air-quality, raising new questions about the health risks posed by dirty water.

With their vast resources and raw materials, the world’s oceans are one of the cornerstones of the quality of human life. According to World Bank figures, 350 million jobs are estimated to be linked to the oceans globally, and 1 billion people in developing countries depend on fish for their primary source of protein.

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.

The world’s oceans are growing more acidic as carbon emissions from the modern world are absorbed by the sea. A new film, “A Sea Change,” explores what this changing chemistry means for fish and the one billion people who rely on them for food. This first-ever documentary about ocean acidification is told through the eyes of a retired history teacher who reads about the problem in a piece in The New Yorker and is inspired to find out more. His quest takes him to Alaska, California, Washington and Norway to talk with oceanographers, climatologists and others.
