A hypothesis is introduced in constructing the statistics of an eddy field, which distinguishes Gulf Stream rings as a separate anomalous feature from the rnesoscale eddy field. Analysis of XBT sections between New York City and Bermuda with rings removed indicates that the therrnocline deepens toward the Gulf Stream from Bermuda and the r.rn.s. displacement of the 15°C isotherm is 50 m or less....
