    International marine science research projects : second inventory of international projects at Sea Grant institutions, 1990
    (Woods Hole Oceanographic Institution, 1991-03) Fenwick, Judith ; Ross, David A. ; Schramm, Cynthia T.
    This inventory of marine science projects at Sea Grant institutions was completed in order to gauge the level and enhance a database of U.S./foreign collaboration in international marine research initiated at U.S. Sea Grant institutions. The inventory was done by the International Marine Science Cooperation Program at the Woods Hole Oceanographic Institution's Sea Grant Office. The first inventory of projects with international components at Sea Grant institutions was done in 1984-85 by the International Program. This second inventory continues in the tradition of the first to "take the pulse" of international interest at Sea Grant institutions. The pulse is very active despite the lack of direct funding accorded the formal Sea Grant International Program at the national level. Of the 122 projects at Sea Grant institutions, however, only 29 were directly funded in part or entirely by Sea Grant. The inventory analyzes data from 122 interntional projects initiated at 20 Sea Grant institutions by profiling and explicating the extent of project foreign locations, sources of funding, areas of expertise for principal investigators, and contacts at foreign and U.S. agencies and institutions. It presents one-page summaries of the 122 projects along with indexes by geographic location, funding source, PI discipline, PI name, and keywords. In addition, this report compares the data from the 1989-90 inventory with that of the 1985 inventory.

    Tectonics of the western Gulf of Oman
    (Woods Hole Oceanographic Institution, 1979-12) White, Robert S. ; Ross, David A.
    The Oman line, running northward from the Strait of Hormuz separates a continent‐continent plate boundary to the northwest (Persian Gulf region) from an ocean‐continent plate boundary to the southeast (Gulf of Oman region). A large basement ridge detected on multichannel seismic reflection and gravity profiles to the west of the Oman line is probably a subsurface continuation of the Musandam peninsula beneath the Strait of Hormuz. Collision and underthrusting beneath Iran of the Arabian plate on which this ridge lies has caused many of the large earthquakes that have occurred in this region. Convergence between the oceanic crust of the Arabian plate beneath the Gulf of Oman and the continental Eurasian plate beneath Iran to the north is accommodated by northward dipping subduction. A deformed sediment prism which forms the offshore Makran continental margin and which extends onto land in the Iranian Makran has accumulated above the descending plate. In the western part of the Gulf of Oman, continued convergence has brought the opposing continental margin of Oman into contact with the Makran continental margin. This is an example of the initial stages of a continent‐continent type collision. A model of imbricate thrusting is proposed to explain the development of the fold ridges and basins on the Makran continental margin. Sediments from the subducting plate are buckled and incorporated into the edge of the Makran continental margin in deformed wedges and subsequently uplifted along major faults that penetrate the accretionary prism further to the north.

    The use of the coastal oceans in the 80's : opportunities for marine geology
    (Woods Hole Oceanographic Institution, 1980-04) Ross, David A. ; Aubrey, David G.
    Events of recent years have clearly indicated that the United States will be making greater use of its coastal and offshore region in the 1980's. Rational use of this area will require the combined talents of scientists, engineers, politicians, environmentalists and others . There will be pressures and needs to use the coastal ocean for nuclear waste disposal, marine mining, disposal of waste materials, and hydrocarbon exploration: these uses will require new answers and technologies for many important marine geological questions. In an effort to identify these questions and determine what is needed to answer them, a group of approximately sixty geologists and marine scientists from academia, industry and the federal government met for a 2-1/2 day workshop at Woods Hole in October 1979. Initially the group looked at six uses of the offshore region: Nuclear Waste Disposal; Sewage, Industrial and Dredge Material Disposal; Offshore Structures; Marine Mining; Hydrocarbon Exploration and Extraction; and Military Related Activities .

    Report C, general data on bottom sediments including concentration of various elements and hydrocarbons in the Persian Gulf and Gulf of Oman. Report D, general data on the geophysical nature of the Persian Gulf and Gulf of Oman
    (Woods Hole Oceanographic Institution, 1978-05) Ross, David A. ; Stoffers, Peter
    This report is divided into two parts; the first concerns the sediments of the Persian Gulf/Gulf of Oman, the second the geophysics of the same area. Data are presented in the first part on sediment texture, mineral composition, pore-water chemistry and hydrocarbon content. In the second part data are given concerning the bathymetry, magnetic gravity and multi-channel seismics. Interpretation and significance of much of the data is discussed.

    The impact of the Law of the Sea Conference on U.S. marine scientific research : report on a questionnaire
    (Woods Hole Oceanographic Institution, 1983-05) Ross, David A. ; Ladner, Rosamund ; Early, Julie A.
    Because of the Law of the Sea Conference and other factors there recently has been a continuing expansion in the legal, economic, and scientific control over the ocean by coastal countries. This paper presents the results of a questionnaire survey mailed to U.S. marine scientists, soliciting their experiences during the last decade in conducting research in the coastal waters of foreign countries and their expectations for the future. Tables present the countries where research had been conducted, methods of and difficulties in obtaining clearance from foreign governments, the affect of foreign rules on design, planning and execution of research, and areas of interest for future research. Fifty-eight percent of the seventy-two respondents (136 originally sent) had encountered difficulties in obtaining permission to work in foreign coastal waters. Forty-nine percent anticipate that Law of the Sea Treaty requirements may cause such problems for them in the future. The respondents made comments and recommendations bearing on future U.S. marine research in foreign waters. One set of tables presents results for the total group; another set presents results for subgroups of those in particular scientific disciplines.

    International marine science research projects : inventory and analysis of selected projects at Sea Grant institutions, 1985
    (Woods Hole Oceanographic Institution, 1985-07) Ross, David A. ; Fenwick, Judith
    The U.S. marine scientific community continues to show an interest in marine research within foreign Exclusive Economic Zones and with foreign scientists and institutions, in spite of the problems, regulations, and increased formalization involved in cooperative international projects. This inventory of international marine science research projects at Sea Grant institutions resulted from discussions on the possible establishment of a U.S. office or center for international marine science cooperation. Such an office has been proposed as one mechanism to assist in developing international marine research projects. The report analyzes data from 98 inventory questionnaires, completed by Sea Grant institutions. It should serve as a reference piece for persons seeking information and assistance in initiating cooperative international marine science research projects. Projects are profiled by sources of funding, disciplines of principal investigators, geographic locations of projects, and general categories of research. Also included are summaries of the completed questionnaires, indexes for quicker access to pertinent areas of the summaries, and information for the reader with further questions or interest in contacting the principal investigator of a specific project.

    Late Cenozoic geology of the Central Persian (Arabian) Gulf from industry well data and seismic profiles
    (Woods Hole Oceanographic Institution, 1988-04) Swift, Stephen A. ; Uchupi, Elazar ; Ross, David A.
    Industry seismic reflection profiles shot in the 60's and early 70's in the central Persian (Arabian) Gulf are used to map two late Tertiary unconformities, and velocity data from a centrally located well is used to convert travel time to depth to the unconformities. The deeper horizon correlates with a regional unconformity at the end of the Eocene in most wells and dips monotonically to the northeast, whereas the shallower horizon is flatter and correlates with the mid-upper Miocene section in one well. Isopach maps based on wells indicate that sedimentation was relatively uniform across the region until the middle to late Miocene. Sediments deposited since the late Miocene thicken from 100-200 m on the Arabian side of the Gulf to >1000 m near Iran reflecting deposition of sediments eroded from the rapidly uplifting Zagros fold-belt. As a result of the rapid deposition, the velocity gradient in the upper 1 km decreases from ~4 km/sec per km near Arabia to about 2 km/sec per km on the Iranian side of the Gulf.

    Workshop on Cooperative International Marine Affairs
    (Woods Hole Oceanographic Institution, 1982-08) Broadus, James M. ; Knecht, Robert W. ; Ross, David A. ; Shusterich, Kurt M. ; Silva, Maynard E.
    This report details the results of a workshop held at the Woods Hole Oceanographic Institution (WHO!) on April 20-21, 1982. The workshop, part of an effort by the Marine Policy and Ocean Management Program (MPOM) of WHO! intended to assist interested developing countries in formulating strategies for ocean resource use and management within their new 200-rnile exclusive economic zones. The effort, presently called the Cooperative International Marine Affairs Program (CIMAP), began in November of 1981 after the William H. Donner Foundation of New York City responded favorably to a proposal submitted by Dr. David A. Ross, Director of MPOM.
