Shellback Expedition, 1952

Shellback Expedition explored the eastern Tropical Pacific. Particular attention was paid to direct measurements of the equatorial and Peru currents. Deep trawls sampled life in subsurface waters of very low oxygen content. The Panama Basin was delineated, and ports were visited in Costa Rica, Peru and Ecuador, including the Galapagos Islands.
