Abstract : 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 m/sec and 27.7 million cu m/sec, 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.
