Distribution of ML-averaged temperature on 5 July measured by uCTD, CTD and gliders. Measurements from CTD and gliders are interpolated to the time of measurement of the uCTD profiles. Measurements from the CTD (gliders) are given in red (green) rectangular boxes. Values written in horizontal (vertical) direction corresponds to the southward (westward) section of uCTD. Colors are high resolution SST (approximately 1.1 km) from the Group of High Resolution Sea Surface Temperature (GHRSST) product. A bias of about 0.5 °C is seen between the satellite-derived SST and the in situ data, probably owing to aliasing of the high-frequency variability (diurnal cycle and trend) and cool-skin effect of measuring SST.
