Temperature data, collected over the past 40 years, was
compiled and averaged in the first known study of mean thermal
conditions throughout the waters of Monterey Bay. The
following results were obtained:
(1) The distribution of mean sea surface temperature
in the Bay was obtained by calculating mean monthly values
at selected grid points and drawing isotherms,
(2) Progressive warming of the upper 100m was observed
to occur in a nearly linear fashion with time, resulting in
a maximum temperature increase of 1.8°C over the 29 year
interval from 1931 to 1960. This implies that the intensity
of upwelling is also decreasing with time,
(3) Geographic variations in the rates of upwelling
and downwelling, causing a relatively "warm tongue" along
the Canyon axis, appeared to be a major element influencing
the dynamics of the Bay, and
(4) Mean currents were inferred from the topographies
of mean monthly isothermal surfaces. Limited comparisons of
the inferred flow to past measured currents were very encouraging
and tended to support the feasibility of such an
inference in the shallow waters and irregular topography of
Monterey Bay.
