Abstract : Techniques were developed to estimate the mixedlayer depth and vertical profile of sea temperature to 440 ft at 4 ocean-station vessels in the North Atlantic. The estimations were based on climatological parameters and concurrent observations of routinely reported surface variables. The estimations are intended as an aid in overcoming data-scarcity problems encountered in the routine objective analysis of the mixed-layer depth and subsurface sea-temperature fields. An operational computer program for analyzing mixed-layer depth is expected to be tested by Jan. 1964. Statistical methods were used to develop the techniques, using approximately 10 yr of BT data for each ship. Climatological parameters were compiled for each surface variable and for sea temperatures at depth. Equations were derived by harmonic analysis to express the mean and standard deviation of each variable as a function of the day of year. The estimations were computed from significant statistical relationships expressed in the form of regression equations. Generalized regression equations applicable at all 4 ships were found to be comparable in accuracy to equations derived specifically for each ship. (Author)
