The SEACOOS remote sensing site integrates a wide range of the observations collected under the SEACOOS program, in one mapserver site:
http://seacoos.org/Data%20Access%20and%20Mapping/BetaMap
The web page allows you to actually measure temperature, chlorophyll from satellite (or temperatures from buoys) and build time series, which are returned as ASCII and also graphs.
Much or our satellite data are available via opendap through here or our web site (http://imars.usf.edu)
