Working in the same think tank but in different roles, two alumni show how the Climate and Society program prepares students for a variety of career paths.

Marie Tharp was a marine scientist in a man’s world. Robert Smalls was a skilled sailor, but held as a slave. Both are now being honored by the U.S. Navy.

A number of organizations are attempting to clean up the water, but solving the problem of ocean plastic pollution will also require big changes on land.

Biological oceanographer Hugh Ducklow describes decades of work in far-flung places to understand the evolving ecology of the oceans. The picture is not always clear.

In much of the world ocean, there is evidence that iron-rich dust blowing from land has fertilized algae during cold period, increasing uptake of carbon from the air, and keeping things frigid. Not here, says a new study.

Seaweed cultivation, altering the chemistry of seawater, or even injecting electrical currents should be studied, say the authors.

A sharp rise in temperatures on land is linked to unusual heating of the Atlantic Ocean, and changes in wind patterns that send that warmth westward.

Fast turnover of carbon between seawater and microbes is a fact, but how it works is largely a black hole. This projects aims to shed light.

Large numbers of icebergs that drifted unusually far from Antarctica before melting into ocean waters have been key to initiating ice ages of the past, says a new study.
