The Gulf Stream influences climate, weather, and ecosystems. It transports the warm branch of the Atlantic Meridional Overturning Circulation (AMOC), which moderates high latitude Northern Hemisphere climate and is projected to decline in a warming climate. In this talk, I will present observational and model-based evidence that the Gulf Stream's interactions with the Labrador Current drive variability all along the Northeast US Continental Slope and Shelf, from temperature to fisheries. Over the last century, these interactions have led to large-scale warming on the Northeast US Slope. Because this warming translates to a buoyancy increase at the western boundary of the North Atlantic that exceeds the buoyancy changes at the same latitude in the east, we can infer a slowdown of the AMOC, albeit with low confidence due to sparsity in the early hydrographic record. I will end with an outlook of major questions for the future, including how we might sustain observations of air-sea turbulent exchange in and near the Gulf Stream for the purpose of better weather prediction and lower uncertainty in the quantification of the ocean carbon sink.
