Oceanographic Observations, North Atlantic Ocean Station BRAVO Terminal Report 1964 - 1974

Observed and interpolated temperature and salinity data, plus computed sigma-t, geopotential anomalies, sound velocities and a limited number of dissolved oxygen values are presented for 1249 oceanographic stations taken by U.S. Coast Guard cutters at Ocean Station BRAVO (56 deg. 30'N, 51 deg....

Description
Summary:Observed and interpolated temperature and salinity data, plus computed sigma-t, geopotential anomalies, sound velocities and a limited number of dissolved oxygen values are presented for 1249 oceanographic stations taken by U.S. Coast Guard cutters at Ocean Station BRAVO (56 deg. 30'N, 51 deg. 00'W) from November 1969 through June 1974. In addition, a time-series analysis of monthly averages of air and sea surface temperature, salinity, and sigma-t are presented for data collected at OS BRAVO since the inception of the oceanographic program in January 1964. This analysis reveals a five year cooling and freshening trend of the surface waters between 1967 and 1971 which resulted in a decrease in density of the surface waters. This decrease in density resulted in a stratification of the water column in the upper 200 meters inhibiting an overturn of the water column and the formation of deep and bottom waterin this area.
