Sept 29: Putting Recent Western North Atlantic Warming into Context

The western North Atlantic is warming faster than much of the rest of the world’soceans, wreaking havoc on the world’s renowned fisheries in this region. This warming has more or less been ongoing since the start of the instrumental record in this region (turn of the 20th century).

Understanding when this warming began and the drivers behind the warming is critical for improving predictions of future oceanographic conditions in the area. Along with colleagues, Dr. Nina Whitney’s work focuses on reconstructing past changes in hydrographic conditions in the Gulf of Maine and Mid Atlantic Bight regions of the western North Atlantic using both geochemical isotope proxies in the shells of Arctica islandica (ocean quahogs), the longest living non-colonial organism in the world, along with high resolution climate model simulations.

Their recent work has shown that warming in the region began in the late 1800’s following 900 years of cooling driving primarily by volcanism, and that much of this warming is related to increases in atmospheric greenhouse gas concentrations and changes in ocean dynamics.

The Environmental Speaker Series is free and open to the public. Talks are held each Thursday at 4:30 pm in Academic Instructional Center West, room 204. Paid parking is available in lot C. Or join us online on Zoom!
