Abstract

A horizontal divergence of 2×10−5 sec−1 was determined by tracking three shallow drogues in the speed axis of the Gulf Stream. Concurrent bathythermograph soundings along a drogue track support this magnitude. The data also provide estimates of the strength of turbulence encountered. In terms of the neighbor diffusivity, they amount to 2×105 cm2 sec−1 for a drogue separation scale of 4 km, and 4×104 cm2.Sec−1 for the 2-km scale.
