The Atlantic Meridional Overturning Circulation at 35°N from deep moorings, floats, and satellite altimeter

Le Bras, I. A.-A., Willis, J., & Fenty, I., 2023. The Atlantic Meridional Overturning Circulation at 35°N from deep moorings, floats, and satellite altimeter. Geophysical Research Letters, 50(10), e2022GL101931. https://doi.org/10.1029/2022GL101931 From 2004 to 2014, the Line W moorings measured a 0.7 Sv yr−1 slowing of the deep western boundary current (DWBC) offshore of Cape Cod. Here, we combine these deep…
