Water mass changes in Florida Straits since 2001

Using 102 repeat hydrographic sections and a machine-learning approach, we define the water masses within Florida Straits and their variability since 2001. We find significant changes in the temperature and salinity properties of the Straits´ constituent water masses, which further drives significant variability in the transport of heat and freshwater into the North Atlantic across 26N. We further combine transport in the Florida Straits from hydrography with the transport across  the RAPID array ordered in salinity space (a new framework for transport calculations). This approach highlights the relative contributions of the subtropical and subpolar/polar systems to the heat and freshwater divergence and water mass transformation north of 26N.
