An Oceanographic and Acoustic Study of a One-Degree Square in the Western North Atlantic.

An intensive Nansen cast survey of a one-degree square in the Western North Atlantic (25 Oct - 11 Nov 1963) revealed significant variations in the distribution of properties. A definite pattern of fine structure of the properties was revealed in the upper 500 meters of the water column. Comparison o...

Description
Summary:An intensive Nansen cast survey of a one-degree square in the Western North Atlantic (25 Oct - 11 Nov 1963) revealed significant variations in the distribution of properties. A definite pattern of fine structure of the properties was revealed in the upper 500 meters of the water column. Comparison of such a structure with historical BT data suggests the possibility of the Antilles Current being more important in heat exchange processes in the upper strata than the energy exchange through atmospheric interaction. Reduction of the oceanographic model of this one-degree square into acoustic information reveals greater variations in convergence zone ranges and wider changes in zone widths than previously expected in a small ocean area.
