Abstract:

A one-dimensional mixed-layer model of ocean thermal structure Camp, 1976 was first modified to determine the effects of a salinity profile on density structure and secondly to observe the added effects of surface salinity flux. The model was tested in August and November-December 1974 with 1 hydrocast data at Ocean Stations HOTEL and PAPA and 2 salinity profiles statistically derived from historical data for six ocean stations and adjusted to correspond to an observed BT. Inclusion of salinity structure did not significantly affect mixed-layer depth or temperature predictions during the summer period. During the winter period, salinity structure tended to inhibit deepening yielding a slightly warmer, shallower mixed layer. Surface salinity flux altered significantly the thickness of the isothermal layer, with decreases in thickness during precipitation E-P0 and a tendency for increased thickness during some periods of net downward heat flux when E-P0.
