New lab group paper
| Updated:
Very exited to share some new research results. This was years in the making and was a real group effort. A 250‐Year, Decadally Resolved, Radiocarbon Time History in the Gulf of Maine Reveals a Hydrographic Regime Shift at the End of the Little Ice Age https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2020JC016579
Radiocarbon measured in absolutely dated Arctica islandica shells is used to track water masses entering and the radiocarbon time series reveal an abrupt regime shift around CE 1860 as a result of oceanographic changes in the North Atlantic. Together, this shift is likely related to broader changes in the Arctic and the Labrador Sea, and a short‐term strengthening of the Atlantic meridional overturning circulation #AMOC, which is followed by a weakening. Thanks to Erin Lower Spies and Nina Whitney @ninawhitney for leading the effort! Stay tuned for more research from the Gulf of Maine.
