Following the Fresh Water
A research team led by Woods Hole Oceanographic Institution (WHOI) found the fingerprint of a massive flood of fresh water in the western Arctic, thought to be the cause of an ancient cold snap that began around 13,000 years ago.

The American Geophysical Union (AGU) has chosen Fiamma Straneo, a physical oceanographer at Woods Hole Oceanographic Institution (WHOI), to deliver the Sverdrup Lecture at this year’s meeting of the Ocean Sciences section held in New Orleans from February 21-26, 2016. The lecture is one of the highest awards the section bestows on its members.

Ocean robots installed off the coast of Massachusetts have helped scientists understand a previously unknown process by which warm Gulf Stream water and colder waters of the continental shelf exchange. The process occurs when offshore waters, originating in the tropics, intrude onto the Mid-Atlantic Bight shelf and meet the waters originating in the Arctic. This process can greatly affect shelf circulation, biogeochemistry and fisheries.
In 2006, scientists using satellite imagery observed an elongated body of warm water from a Gulf Stream warm-core ring intruding along the shelf edge, extending hundreds of miles from Massachusetts towards Cape Hatteras, NC.
“A lot of people were surprised by this,” said Weifeng ‘Gordon’ Zhang, associate scientist at Woods Hole Oceanographic Institution (WHOI), and lead author of the study published [today] in Geophysical Research Letters. “Normally, the Gulf Stream water, which is very warm and buoyant, doesn’t come in direct contact with the water on the continental shelf, which is much colder. There is a cascade of potential implications that need further study.”

Heat Release from Stagnant Deep Sea Helped End Last Ice Age
The build-up and subsequent release of warm, stagnant water from the deep Arctic Ocean and Nordic Seas played a role in ending the last Ice Age within the Arctic region, according to new research led by an international team of scientists.
The study, published today in Science, examines how the circulation of the combined Arctic Ocean and Nordic Seas – called the Arctic Mediterranean – changed since the end of the last Ice Age (~20,000-30,000 years ago). The results highlight the important impact that changes in ocean circulation can have on climate.
