Cover Story: Sea surface temperature (SST) is a fundamental property of the ocean surface and one of the first ocean variables to be studied using satellites. Quantifying the accuracy and precision of satellite SST data requires comparing it with in-situ data. In nearshore coastal waters this is not well known, owing to a lack of in-situ data. Here, we compare a Smartfin, a surfboard fin designed to measure ocean temperature in the nearshore, with an infrared SST autonomous radiometer (ISAR) and an underway oceanographic temperature sensor (UOTS) on an expedition through the Atlantic Ocean. We found a mean absolute difference between Smartfin and UOTS of ­0.06 K and Smartfin and ISAR of 0.12 K. Differences were related to sampling depth and environmental variability. Results add confidence to the use of Smartfin as a tool for satellite validation. View this paper
