Three things you may not know about sea level rise

Since the turn of the 20th century, seas have risen six to eight inches globally. New technologies, along with a better understanding of how the oceans, ice sheets, and other components of climate interact, have helped scientists identify the factors that contribute to sea level rise.

Dense Antarctic water returning to the Atlantic

“This region, the Scotia Sea, is unique in that it hosts several different physical mechanisms which launder dense water to make it lighter within a relatively small basin (the Southern Scotia Sea),” says co-author Dr. Kurt Polzin of WHOI. “This small basin relative to a relatively large volume transport enables researchers to assess changes in water mass production ultimately coming from the Antarctic Shelves on a biennial basis, compared to decadal time scales from other sections.”

Breaking Ice: Science at the Top of the World

Since 2003, the Beaufort Gyre Exploration Project at the Woods Hole Oceanographic Institution has given us an up-close look at one of the fastest-changing parts of the world. In 2018, the Ocean Media Institute at Montana State University sent Hugo Sindelar to join the annual expedition aboard the Canadian icebreaker Louis S. St. Laurent to see how the scientists and engineers involved in the project bring back their hard-earned data and to hear what they’ve learned so far.

Study Finds No Direct Link Between North Atlantic Ocean Currents, Sea Level Along New England Coast

A new study by the Woods Hole Oceanographic Institution (WHOI) clarifies what influence major currents in the North Atlantic have on sea level along the northeastern United States. The study, published June 13 in the journal Geophysical Research Letters, examined both the strength of the Atlantic Meridional Overturning Circulation (AMOC)—a conveyor belt of currents that move warmer waters north and cooler waters south in the Atlantic—and historical records of sea level in coastal New England.
