Transport Float Measurements and Hydrographic Station Data from Three Sections across the Gulf Stream near 67 degrees W R.V. CRAWFORD Cruise 168, June-July 1968.

Three transects of the Gulf Stream between Cape Cod and Bermuda including data from transport float free fall instrument observations and hydrographic stations are presented and compared. Measured volume transport by transport float observations appeared to decrease from 180 plus or minus 20 to 113 plus or minus 20 million cu msec in a period of less than one week. Geostrophic calculations based on a reference level at the ocean bottom gave a volume transport of 100 to 120 million cu msec. Although the Stream appeared to extend to the ocean bottom on all three sections, deep countercurrents westward flow were also observed on two of the sections. Author
