Figure 2 shows the distribution of surface temperature observed with the thermograph at 4 m of depth and the distribution of temperature, salinity and oxygen in the profile off Baia dos Tigres. Comparison with earlier cruises at about the same time in 1985 and 1986 shows that the inshore surface water temperature is similar to that observed in 1986 but some 2°C colder than that found in 1985. The vertical section off Baia dos Tigres shows upwelling of subsurface water in the shelf area from about 75 m depth towards the surface.
