Observations of sea temperature, wind and hydrography obtained
during the three months' period of MAM 77 - CUEA experiment (JOINT-II)
along the C-line, near 15°S are described. Wind and temperature
observations made during March - May 1977 are compared to demonstrate
that a relationship exists.
Linear correlation analysis was performed on the temperature
data and on the alongshore component of wind and wind stress. Auto-correlations
and cross-correlations were computed for the temperature
and wind. These analyses show that the alongshore fluctuations of
the wind are very similar at the different stations, and the wind at
each location was favorable for upwelling throughout the period of
measurements. Temperature fluctuations in the near-surface, the nearshore
and the near-bottom water over the shelf are coherent with
temperature changes at a depth of 150 - 200 m over the upper slope.
Temperature-wind analysis show that there is a good response of
the near-surface temperature to the wind force. The time lag between
the wind and the near-surface temperature was about 24 hours nearshore;
the wind always led the temperature. Subsurface temperatures were
not as well correlated with the alongshore wind, both negative and
positive correlations were observed in this analysis, and the time
lag between the wind and temperature was variable; on a few occasions
the temperature led the wind.
Vertical sections of sigma-t and temperature indicate the
existence of conditions consistent with upwelling. Oscillation in
the wind with periods of several days caused significant changes in
the region inshore of 25 km. / Graduation date: 1979
