There is coverage by a large number of sensors. Here we show examples of recent data from altimeters (giving sea surface height, SSH), and ocean colour sensors (giving a measure of chlorophyll concentration). Finally we show a map of sea surface temperature (SST), which is an amalgam of infra-red and microwave sensing plus model data. All data are provided by RSDAS and AVISO and plotted here at NOCS.
