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.

Over the past 30 years, U.S. trade negotiators have pressured Japan to open its market to foreign goods and services. These outside pressures, known as gaiatsu in Japan, have been based partly on economically coercive bargaining and partly on invitation. The coercive element, which has entailed threats of retaliatory market constriction should a satisfactory resolution of the market opening dispute not be forthcoming, generally has been a necessary ingredient in obtaining concessions from Japan. The invitational component, which has included requests for U.S. pressures from Japanese interests who favor reforms, generally has facilitated Japanese concessions and made the gaiatsu process unique.

The Rural Abandoned Mine Program (RAMP) was designed to restore agricultural land that has been disturbed by strip mining. The program is carried out by the Department of Agriculture's Natural Resources Conservation Service at a current cost of about $10 million per year--a modest share of total Federal abandoned surface mining reclamation efforts that currently exceed $110 million per year, and that has been higher in the past. Critics contend that the RAMP program is inefficient and duplicates other Federal and State reclamation activities. Proponents contend that the effort has been underfunded and thus unable to fulfill its goals and to realize potential efficiencies. With the efforts of the 104th Congress to cut Federal expenditures and programs, the RAMP program appears highly vulnerable to being cut or eliminated.

The Bureau of the Census estimated the U.S. resident population at nearly 262.0 million as of March 1, 1995, up 5.3% from 248.7 million in 1990, 15.6% from 226.5 million in 1980, and 73.1% from 151.3 million in 1950. The population has grown, on average, by slightly under 1.1% a year since 1990—faster than the world's developed countries overall (0.6%), but slower than the developing countries (1.9%,). Current projections indicate a possible U.S. population of 392.0 million by 2050—over 250% growth in a century and nearly a 50% increase from 1995.

This report focuses on the exchange-rate system set up at Bretton Woods, its breakdown in the 1970s, the current system of managed floating and, finally, proposals to return part or all the way to a more fixed-rate system.

Legislation to designate wilderness areas on Federal lands administered by the Bureau of Land Management has been introduced in several recent Congresses. Bills in the 104th Congress include H.R. 1500, America's Red Rock Wilderness Act of 1995, and H.R. 1745 and S. 884, Utah Public Lands Management Act of 1995 (identical as introduced). H.R. 1500 would designate 5.7 million acres of wilderness, and reserve Federal water rights. H.R. 1745/S. 884 would designate 1.8 million acres of wilderness, release areas not designated as wilderness, deny Federal reserved water rights, and provide management directions, some of which are exceptions to the standards established in the Wilderness Act.
