Where can I get current sea-surface temperature data?
The data on GeoChange are no newer than 1991. More comprehensive data are available at the Physical Oceanography Distributed Active Archive Center (PO.DAAC) at JPL in Pasadena. For specific data covering coastal areas, consult the NOAA CoastWatch Program or its data access system, the NOAA CoastWatch Product Search. Some overview information on CoastWatch is available here.
