The Dedicated Vessel Research Program Records, which date from 1972 to 1980, document the entire scope of the DVRP project
undertaken in the late 1970s, and includes records generated by the DVRP as well as other records and publications scientists
used, read, or considered over the course of the project. The tuna/porpoise problem is heavily documented. The collection
consists of agreements, summaries, reports, permits, notes, plans, "green books", logs, transcripts, letters, sighting records,
raw data, statements, expendable bathythermographs ("XBTs"), correspondence, news clippings, publicity releases, photographic
slides, and video. The collection is divided into five series: Background Material, Cruise Files, Statements and Stocks of Porpoises (SOPs), Correspondence and Reports, and Media.
San Diego, a geographical hot-spot for tuna fishing, was known as the Tuna Capital of the World from the early 1930s to the
late 1970s. Since tuna often associate with porpoise in their native habitats, fisherman typically set nets around visible
herds of porpoise to catch tuna. This type of fishing for tuna is known as purse seining, or "net fishing", and has led to
the killing of many porpoises. Purse seines, first used in Southern California in 1916, are used to catch many different species
of fish. In the late 1950s and early 1960s, as foreign competition out-caught American tuna fishermen, the U.S. bait-boat
fleet slowly switched to purse seine gear to increase the number of tuna captured.
