The Flickr set documents the field work of Isaac Ginsburg (1886-1975), an Ichthyologist who spent much of his career with the U.S. Bureau of Fisheries (1922-1956). His chief scientific interest was the marine fishes of the Gulf of Mexico. In 1935, he went to Panama for the Bureau of Fisheries, to study sites connected with the fishing industry. The photographs selected document his work in the field, showing examples of wetlands and shoreline, facilities at Barro Colorado Laboratory (later to become the Smithsonian Tropical Research Institute), locals and colleagues using cayucos in local waters, local vegetation, and places enroute.
