Abstract
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 temf>oral 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 venicallv for the latter cruise.
