Thermal conditions in Monterey Bay during September 1966 through September 1967 and January 1970 through June 1971 were described by comparing direct observations taken at nearly weekly intervals to the long-term (40 years) averages, or '"norms," developed by Lammers (1971). Station locations were distributed throughout the bay with most located over the axis of Monterey Submarine Canyon or in the southern half of the bay. Temperature data from three transects taken out to a distance of some 80 miles in August 1970 were compared to observed thermal conditions in the bay during four quasi-synoptic (one to three day) periods in August. it was found that me norms provide an excellent basis to which direct temperature observations during quasi-synoptic periods may be compared. Such comparisons of certain thermal indices (depth of the 9°C isotherm, temperature at 20 meters, and sea surface temperature) at key locations (southern shallows, deep canyon, and shallow canyon) are valuable parameters in identifying the three climatic seasons (upwelling, oceanic, and Davidson Current) as well as the existence of anomalous thermal conditions. Further study into the nature of these anomalies could lead to better understanding of the dynamics of water movements in Monterey Bay.
