The Survey, East Carolina University, and the International Geological Correlation Program (IGCP) Project 156 sponsored a workshop on the potential for discovery of useful phosphate deposits in the Caribbean. The workshop was held at East Carolina University, Greenville, North Carolina, in July 1984. Scientists from Colombia, the Dominican Republic, Costa Rica, Honduras,
Jamaica, Guatemala, Venezuela, and Mexico met with U.S. specialists to consider the regional and detailed geologic: studies needed to assess the rock phosphate potential that would provide an accessible local source of agricultural fertilizer. The development of this resource will be a giant step towards mitigating the region's severe food production problems. As a result of the workshop, the country representatives now are working to establish a Caribbean basin phosphate resources group to plan and coordinate phosphate assessment in the region. The U.S. Geological Survey and the IGCP Project 156 will provide advice and assistance to this regional resource group.
In July 1983, the Survey initiated a technical assistance program in coalresources assessment and exploration with Costa Rican counterparts in the Gerencia de Exploracion de Refinadora Costarricense de Petroleo (RECOPE) under the auspices of the Agency for International Development. A Recope geologist received on-the-job training in coal exploratory and drillhole geophysical logging techniques with Geological Survey counterparts in the Powder River Basin of Wyoming during that summer. In 1984, three of nine coalbearing areas in Costa Rica were targeted for study; in the Volio area in the southeast, RECOPE is drilling to determine the quantity of coal available; reconnaissance mapping and surface exploration are being done in the
Venado area to the north and in the
Zont area to the east. Survey personnel
advise and train Recope counterparts in coal mapping and resource assessment methodologies, exploratory drilling and downhole geophysical logging techniques, and coal sample collection, processing, and analysis. Assessment of the quality of Costa Rican coal will be accelerated with completion of a Survey-designed coal analytical laboratory in RECOPE under the leadership of a Costa Rican chemist who received training this year at a Surveyselected commercial laboratory in the United States. Development of coal
resources of the Caribbean region for
utilization in the production oi electricity will decrease the dependency on imported oil. As a source to replace fuelwood, coal utilization can alleviate severe problems caused by deforestation in the region.
A geologic synthesis and mineral resource assessment of Colombia was completed in 1984 with cooperation of scientists from the Survey and the Instituto de Investigaciones GeologicoMineras in Colombia. This project was designed to organize and review existing geologic information to identify terranes in Colombia that have the greatest potential for new mineral discoveries. Mineral deposit models were developed and adapted for deposits that occur in Colombia or in similar terranes elsewhere, and guides for further mineral resource studies and assessments were presented. The cooperative review provides a solid base for the planning of more detailed programs of exploration in South and Central America and Caribbean nations. Concurrent and follow-up cooperative studies thus far undertaken include assistance in the establishment of a microcomputer-based gcochemical data base, workshops and
assistance in the conduct of geochemical surveys and chemical analyses, planning of cooperative marine mineral research, seminars for a national rock phosphate assessment program, and research for a national geologic hazards reduction program. Results of the assessment have been released as U.S. Geological Survey

Technical assistance and institutional development continued in 1984 in Peru where Survey scientists trained and guided geologists and geochemists of the Empresa Minera del Centra del Peru in geological and geochemical mapping and in sample processing and analyses at a Survey-designed laboratory. Investigations continued in the Puquio prospect and began in the Acos concession, which are in the Sur Medio region. Frequency distribution tables, single and multielement distribution maps, preliminary geologic maps, and accompanying reports are in preparation.
South Pacific-East Asia
The U.S. Geological Survey's Research Vessel Samuel P. Lee completed a 3-month, 4-leg resource appraisal cruise in the southwest Pacific in 1984 as part of "Operation Deep Sweep," a pole-topole expedition designed to obtain data to further the knowledge of tectonic processes and resource potential of the Pacific Basin. The scientific expedition, the second in as many years, is a continuation of the Australia-New Zealand-United States (anzus) Tripartite Geoscientific Resource Investigation in the southwest Pacific under the direction of the Committee for Coordination of Joint Prospecting for Mineral Resources in South Pacific Offshore
Areas (CCOP/SOPAC). The expedition took the ship from San Francisco to the Bering Sea and Hawaii, from there to international waters offshore of the
nations of Kiribati, Samoa, New Zealand, Antarctica, Fiji, Tonga, Vanuatu, and Papua New Guinea, and returning to San Francisco via the Marshall Islands and Hawaii. Results of the Antarctica portion of the cruise are described in the article titled The Antarctic Leg of "Operation Deep Sweep" in the Geologic Investigations chapter.
The recently completed ANZUS-CCOP/ SOPAC investigation was successful in delineating structural and stratigraphic features that may be promising mineralor energy-resource targets. In the Tonga-Lau region, a shallow magma chamber was identified that could possibly be a source for polymetallic mineralization. In Vanuatu, the Torres-Santa Cruz basin was found to be quite extensive (over 7,000 square miles) and to contain sediment about 3 miles thick. The sedimentary basins associated with the Central Solomons Trough and offshore New Ireland basin in eastern Papua New Guinea were defined further and found to contain structures that could trap oil and gas.
The Geological Survey conducted a 6-month pilot study to analyze Tertiary sedimentary basins in the CircumBorneo offshore areas of Malaysian Sarawak and Sabah, Brunei, Indonesian Kalimantan, and the southwestern Philippines as a forerunner to a planned program in basin analysis of the East Asia Region (fig. 1). The study was undertaken as part of a proposed cooperative program for the evaluation of sedimentary basins for the International Union of Geological Sciences and was carried out in cooperation with the United Nations Coordinating Committee for Joint Prospecting of Mineral Resources in Asian Offshore Areas. The objective of the pilot study was to demonstrate methodologies and to assist the nations involved in an assessment of the petroleum resources of the region. The analysis was done within the extended framework of the Circum-Pacific Map Project in that data was supplied by the countries involved,
Information Systems Division
Budget And Personnel
At one of the demonstration booths set up in the center, a SuperBrain equipped with a Maxtex XCEL graphics board displays a design. The SuperBrain aJso has software to drive the Bausch Sr Lomb DMP-29 plotter.
The Information Systems Division provides support and advice to the Director of the U.S. Geological Survey, the Department of the Interior, other government agencies, and the other Divisions of the Survey on all matters relating to Bureau information technology and automated data processing (ADP) services. It provides these services along with acquisition assistance for users of large general-purpose computers, smaller special purpose computers, and telecommunications. The Division provides for coordination and growth of information systems through systems analysis and design and conducts ADP research into better ways to use technology to solve mission-related problems. It is responsible for guidelines for data standards, data administration, and data base management.
The Information Systems Division had a budget of $20 million for fiscal year 1984. Other Survey Divisions and Department of the Interior and Federal agency users provided funding.
As a Department of the Interior General Purpose Computer Center, the Division computing facilities were available to other Interior offices and bureaus as well as to all Survey Divisions.
Division staffing consisted of 167 fulltime employees, primarily computer specialists, computer analysts, mathematicians, systems programmers, computer scientists, and technicians. The staff was augmented by part-time and intermittent employees and contract personnel who greatly assisted in fulfilling the mission of the Division. These employees served customers from the five ADP
