In support of meteorological observations during the Line Islands Expedition the U.S.C. G.S. Ship SURVEYOR made oceanographic observations between the Hawaiian Islands and 3 degrees S. A hydrographic section from Hawaii southward crossed the North Equatorial Current and the Countercurrent, the transports of which were 22.1 million cu msec and 27.7 million cu msec, respectively. Two sections across the Equatorial Undercurrent, parallel to each other at a distance of 90 miles, revealed a fine structure of the Undercurrent not previously observed. Two current meters anchored near the island of Palmyra showed predominantly semidiurnal tides and a superimposed flow to the north. Current measurements during 11 days at 6.5 degrees N from the anchored ship indicated that the Countercurrent was not present during most of this period. Flow was mostly to the west and north.
