Radionuclide Data from GEOTRACES Improve Particle Flux Estimates

by K. Matsumoto 7 January 201927 September 2022

New measurements of multiple radionuclides in the Atlantic Ocean offer a robust constraint on the sinking flux of particles and associated vertical fluxes of biogeochemically important elements.

Why Is the Gulf of Maine Warming Faster Than 99% of the Ocean?

Laura Poppick, freelance science writer by L. Poppick 12 November 20182 March 2023

The Gulf of Maine’s location at the meeting point of two major currents, as well as its shallow depth and shape, makes it especially susceptible to warming.

Energetics of Western Boundary Current Surface Flows Are Similar

by J. Sprintall 31 July 201822 July 2022

Despite different wind forcing and air-sea heating conditions, the surface layer energetics of two Western Boundary Current systems in different ocean basins are surprisingly similar.
