work Program, and the Earthquake
Hazards Reduction Program. As an
initial contribution to the Carribean
program, the Geological Survey
published Circular 925, Earth and
Water Resources and Hazards in
Central America, which is a review of
information available for natural
resources in the region and the potential
impact of geologic hazards such as
earthquakes, landslides, and volcanic
eruptions. Survey scientists have briefed
officials of the Department of the
Interior, the Department of State, and
the U.S. Agency for International
Development throughout the year to
acquaint them with the resource and
hazards potential of the region and to
outline the Survey's proposals for study.

The Caribbean nations have onshore,
and possibly offshore, deposits of gold,

silver, and, to a lesser extent, platinum.
Coal and rock phosphate deposits are
known but unassessed. Potential areas
for oil and gas development are
untested for the most part. Geothermal
energy resources are developed locally,
but their potential for development
elsewhere is just now being considered.
Development of reliable potable water
supplies and their protection from
pollution are of considerable interest in
the Caribbean nations, and mitigation of
the risks from geologic hazards is
necessary to the safety and well-being
of the inhabitants. As initial activities in
the Caribbean basin, the Geological
Survey proposes onshore and offshore
energy- and mineral-resource studies,
geologic and hydrologic surveys, and
geologic hazards studies. Programs of

Resource Assessment of Colombia.

The Geological Survey and the Corporacion Autónoma Regional del Cauca, a Colombian organization similar to the Tennessee Valley Authority, are cooperating in a project to simulate by mathematical model the streamflow of the Cauca River in northwestern Colombia. Colombian scientists will evaluate the applicability of a Surveydeveloped model to the Cauca River to guide the operation of a dam which will become functional in early 1985. Satellite data relay also will be used with the model to obtain realtime data on river stages and meteorologic conditions for realtime operation of the model.


Technical assistance and institutional development continued in 1984 in Peru where Survey scientists trained and guided geologists and geochemists of the Empresa Minera del Centro del Perú 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.

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,

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

Information Systems Division



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

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 also has software to drive the Bausch & Lomb DMP-29 plotter.
