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.

Due to the high volume and complexity of its work, Congress divides its tasks among approximately 44 committees with 154 subcommittees. The House and Senate each has its own committee systems, which are similar. Within chamber guidelines, however, each committee adopts its own rules; thus, there is considerable variation among panels.

The release of the nerve agent Sarin in Tokyo's subway system on March 20, marks the first clearly non-state terrorist use of chemical weapons. The agent was highly diluted andmfatalities were relatively few (10), though the number of injured was substantial (5,000+, with 600 hospitalized). This incident clearly indicates the potential political effectiveness of chemical weapons against an unprotected civilian population. Once a population has been sensitized by an incident like this, even the threat of CW can become significantly disruptive. Some have credited fear of another attack with contributing to the cautiousness of the Japanese police investigation

U.S.-China economic ties have expanded substantially over the past several years. China is now the third largest U.S. trading partner, its second largest source of imports, and its fourth largest export market. However, U.S.-China commercial ties have been strained by a number of issues, including a surging U.S. trade deficit with China, China's refusal to float its currency, and failure to fully comply with its World Trade Organization (WTO) commitments, especially its failure to provide protection for U.S. intellectual property rights (IPR). This report explores these issues in detail, especially concerning the lack of protection for U.S. IPR.

U.S. policymakers in Congress face a series of often interrelated security, economic, and political issues in relations with South Korea.

This report discusses congressional interest in the leadership change and economic transformation underway in China, which has grown substantially over the past two years.

Congressional concern with China grew in 1995 as a result of reports of the serious decline in the health of senior Chinese leader Deng Xiao-ping.

As human activity continues to change and modify natural areas, widespread extinctions of plants, animals, and other types of species result. In 1992, negotiations conducted under the auspices of the United Nations Environment Programme (UNEP) were completed on a comprehensive global treaty to protect biological diversity (biodiversity). In June 1993, President Clinton signed the treaty and sent it to the Senate for advice and consent. It is not pending in the Senate. The treaty entered into force on December 29, 1993. As of May 15, 1995, 118 nations had ratified the treaty.

Congressional concerns focused on human rights, Haitian migration, socioeconomic conditions, and drug trafficking.
