Abstract: A new dataset of sea surface temperature (SST) has been generated from the observations of the drifting buoys of NOAA's Global Drifter Program. Estimates of SST at regular hourly time steps along drifter trajectories are obtained using a novel approach which consists in fitting to observations a mathematical model representing simultaneously SST diurnal variability and SST low-frequency variability. Subsequent estimates of non-diurnal SST, diurnal SST anomalies, and total SST as their sum, are derived with their respective standard uncertainties. This Lagrangian SST dataset has been developed to match the existing hourly dataset of position and velocity from drifters, notably providing new opportunities to investigate upper-ocean processes controlling SST variability.
Bio(s): Dr. Shane Elipot is a physical oceanographer who is currently a research assistant professor at the Rosenstiel School of Marine and Atmospheric Science at the University of Miami in Miami, Florida. Elipot received his PhD in Oceanography from the Scripps Institution of Oceanography at the University of California, San Diego in 2006. In 2007-2008, Elipot was a National Research Council postdoctoral research fellow at the NOAA Atlantic Oceanographic and Meteorological Laboratory in Miami, Florida. In 2009, Elipot joined the UK National Oceanography Center in Liverpool as a physical oceanographer. In 2013, Elipot returned to Miami at the Rosenstiel School first as a scientist, then as a research professor starting in 2019. Elipot’s research is focused on using in situ observations and model outputs to understand the kinematics and dynamics of ocean currents, from submesoscales and mixing processes to macroscales and the global thermohaline circulation. Throughout his entire career, Elipot has been contributing to, and working with, the data of NOAA’s Global Drifter Program
