    Hydrocarbons, polychlorinated biphenyls, and DDE in mussels and oysters from the U.S. Coast - 1965-1978 - the mussel watch
    (Woods Hole Oceanographic Institution, 1982-10) Farrington, John W. ; Risebrough, Robert W. ; Parker, Patrick L. ; Davis, Alan C. ; De Lappe, Brock ; Winters, Kenneth ; Boatwright, Dan ; Frew, Nelson M.
    Mytilus edulis, Mytilus californianus, Crassostrea virginica and Ostrea equestris were sampled at 90 to 100 stations around the United States coastline during each of three years- 1976, 1977, 1978. Data for concentrations of PCB, DDE, total hydrocarbons, gas chromatographically unresolved complex mixture hydrocarbons, and selected aromatic hydrocarbons are presented for most of the samples. Similar data for monthly samples of Mytilus edulis from Narragansett Bay, Rhode Island, U.S.A. and Mytilus californianus from Bodega Head, California, U.S.A. and laboratory intercalibrations are presented and discussed. Monthly temporal changes of factors of two to ten were found for ·organic pollutants in mussels from the Narragansett Bay station. Concentrations of PCBs and fossil fuel hydrocarbons for some urban stations were one to two orders of magnitude higher than those in remote areas. The northeast "megapolis" of the U.S. coast from the Chesapeake Bay area to Boston, Massachusetts clearly shows elevated concentrations of PCBs and fossil fuel hydrocarbons. The composition of aromatic hydrocarbons in samples with elevated concentrations shows both the influence of oil spill or chronic oil inputs and pyrogenic sources.

    Preliminary cruise report ATLANTIS II - cruise 8 : International Indian Ocean Expedition, July 5, 1963 - December 20, 1963
    (Woods Hole Oceanographic Institution, 1963) Miller, Arthur R. ; Risebrough, Robert W.
    ATLANTIS II was delivered to the Woods Hole Oceanographic Institution on January 31, 1963. After some short cruises she left Woods Hole on July 5 to participate in the International Indian Ocean Expedition, her first major effort of long duration since her delivery. Eight was a strict test of the capabilities , endurance, Cruise facilities and comfort for which she was designed. The investigations in the Indian Ocean were per haps unique among other cruises of the Exped~t ion in that full coverage of the Arabian Sea was obtained during the Southwest Monsoon in August and September. Further coverage to the south was obtained in October and November where southeast winds were predominant. Inclusion of the Red Sea as part of the Expedition, the total number of hydrographic stations completed during this portion of the cruise was 193, consisting of observations more or less at standard depths to the bottom. These observations, together with various meteorological measurements and chemical analyses are being processed and evaluated, Geophysical observations such as bathymetry and magnetometer results are also being processed along with the navigational positions from the VLF Navigation System.

    Bird log data : Atlantis Two - cruise 8, International Indian Ocean Expedition
    (Woods Hole Oceanographic Institution, 1964) Pocklington, Roger ; Risebrough, Robert W.
    Following the "Preliminary Guide to the Birds of the Indian Ocean" (Watson, Zusi & Stover, Smithsonian Institution, 1963} our Indian Ocean Bird Log begins at a position (20°N, 37°30'E) in the Red Sea off Port Sudan which we reached on the afternoon of l August, 1963. Thus the southern portion of the Red Sea and the Gulf of Aden are included in the area covered by our Indian Ocean records. The northern boundary line is the southern coast of Arabia, 20°N line to India and the west coast of India from Bombay to Ceylon. The furthest point East that we reached is Colombo (7°N 80°E) and the eastern boundary line runs from there through the Chagos Is. (6°S 71°E) to Mauritius (20°S 57°30'E) and the southern tip of Madagascar. The western boundary is the coast of Africa as far south as cape Delgardo (10°30'S 40°30'E) thence via the Comoros to Madagascar. We quit the region east of Lourenco Marques (26°S 37°E) around noon on the 11 November, 1963. About one third of the area of. the Indian Ocean falls within these bounds.
