Scientists Unveil New Map of Hawai'i Sea Floor
U.S. Geological Survey (USGS) scientists, in cooperation with the Japan Marine Science and Technology Center (JAMSTEC), the University of Hawai'i, and the Monterey Bay Aquarium and Research Institute, have recently published a new colored map showing the topography of the Hawai'i sea floor and chain of islands. Prominent geologic features of the sea floor, including landslides, seamounts, fracture zones, and volcanic fields, are portrayed in vivid color and shown in shaded relief. JAMSTEC led the collaborative survey of the sea floor, which used submersible crafts, rock dredges, and sediment piston cores to sample and observe the sea-floor sites. The map shows updated information on lava flows (current through summer 2003) and defines submarine rift zones—the sites of past and, most likely, future eruptions. The full reference for the map is Eakins, B.W., Robinson, J.E., Kanamatsu, Toshiya, Naka, Jiro, Smith, J.R., Takahashi, Eiichi, and Clague, D.A., 2003, Hawaii's volcanoes revealed: U.S. Geological Survey Geologic Investigations Series I-2809. An online version of the map is available. For additional information, please contact Barry Eakins, USGS, at 650-329-5237 or beakins@usgs.gov.
