SST fields derived from AVHRR imagery are compared with subsurface temperature and surface dynamic height fields. The in-situ data collection was part of the Coastal Transition Zone CTZ cold filament experiments of 1987 and 1988. The results of the 1987 cruise show a subsurface maximum in the correlation coefficient between AVHRR SST and in-situ temperature at depth for all three phases of the cruise which is attributed to the temporal offset between the satellite image and the data collection. The results of the 1988 cruise show maximum correlations at the surface with significant correlations at the 95 level of confidence to about 130-150 m depth, with positive correlations to 310-350 m depth. Comparing the results of the 1987 and 1988 cruises shows that the offshore filament was much stronger both horizontally and vertically for the latter cruise.
