Scientific expeditions -- Pacific Ocean

Charles Haskins Townsend served as the Director of the New York Aquarium (NYA) from 1902 to 1937. This collection includes correspondence and subject files during his tenure as Director, articles and reports on such subjects as Northern fur seals and Galapagos tortoises, whaling records that he used to create maps of whale distribution, and photographs he took during trips and expeditions to locations including the Bahamas, Canada, California, and Alaska.

The New York Zoological Society's Department of Tropical Research, led by William Beebe, used the diesel schooner Zaca for two expeditions, the first in 1936 in the Gulf of California, and the second in 1937-1938 in the Eastern Pacific. These records include station data, dredging and net haul records, vertebrate catalogs, miscellaneous correspondence, and data on invertebrates, fishes, and fish stomach examinations.
