Acoustic Thermometry of Ocean Climate: Marine Mammal Issues

Description: After global warming became a concern in the mid-1950s, researchers proposed measuring deep ocean temperatures to reveal any significant trends in core ocean warming. Acoustic thermometry can detect changes in ocean temperature by receiving low-frequency sounds transmitted across an ocean basin because the speed of sound is proportional to water temperature. Acoustic Thermometry of Ocean Climate, or ATOC, is an international program involving 11 institutions in seven nations. It is designed as a 30-month "proof-of-concept" project to provide data on possible global climate change, with funding provided by the U.S. Department of Defense. A debate has arisen over ATOC's impact on marine mammals versus the benefits of better global warming information derived from ATOC. This report dicusses the ATOC program and related concerns.

Dolphin Protection and Tuna Seining

Description: From its inception in 1972, one of the goals of the Marine Mammal Protection Act (MMPA) was to reduce the incidental mortality of dolphins in the ETP tuna fishery. Regulations promulgated under MMPA authority set standards for tuna seining and motivated technological improvements that reduced dolphin mortalities in this fishery -- by 1977, annual dolphin mortality by U.S. tuna seiners had declined to about 25,450 animals. Despite the extensive mortalities, no ETP dolphin population has been listed as endangered or threatened under the U.S. Endangered Species Act. However, two ETP dolphin stocks were listed as depleted under the MMPA.

Fishery, Aquaculture, and Marine Mammal Legislation in the 108th Congress

Description: This report discusses policy and legislation regarding fish and marine mammals. These animals are important resources in open ocean and nearshore coastal areas. Commercial and sport fishing are jointly managed by the federal government and individual states. Many laws and regulations guide the management of these resources by federal agencies.
