The Flying Fish, an untethered oceanographic sensor platform with acoustic homing capability
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1986-05)
The Flying Fish is an autonomous, streamlined, gravity driven underwater vehicle of high speed (15 knots) vertical excursions to depths of 6000 meters. This prototype uses short baseline acoustic interferometry to guide ...
Osmium isotope systematics of the Proterozoic and Phanerozoic ophiolitic chromitites : in situ ion probe analysis of primary Os-rich PGM
In-situ 187Os/188Os ratios are determined on Os-rich platinum-group minerals in podiform chromitites both in the Proterozoic ophiolite, Eastern Desert, Egypt, and in the Phanerozoic Oman ophiolite. Because they have very ...
Reconstruction of the Talkeetna intraoceanic arc of Alaska through thermobarometry
(American Geophysical Union, 2008-03-07)
The Talkeetna arc is one of two intraoceanic arcs where much of the section from the upper mantle through the volcanic carapace is well exposed. We reconstruct the vertical section of the Talkeetna arc by determining the ...
A group of junior faculty members and UCAR junior scientists convened in Boulder, CO on June 16-18, 2003 for discussion on future scientific directions. This report summarizes the goals and products of one of the three ...
Sea surface temperature and salinity variability at Bermuda during the end of the Little Ice Age
(American Geophysical Union, 2008-07-09)
We use geochemical and isotope measurements on a 225-year old brain coral (Diploria labyrinthiformis) from the south shore of Bermuda (64°W, 32°N) to construct a record of decadal-to-centennial-scale climate variability. ...
United States electronic chart display and information system (ECDIS) test-bed project : system requirements specification
(Woods Hole Oceanographic Institution, 1991-08)
In 1989 the Maritime Safety Committee (MSC) of the International Maritime Organization (IMO) adopted a provisional performance Standard for ECDIS (MSC/Circ. 515). This standard defines an electronic chart display and ...
Rather‐high‐frequency sound scattering by swimbladdered fish
(Acoustical Society of America, 1985-08)
A new model describes acoustic scattering by swimbladdered fish of lengths from at least 8 to 36 wavelengths. It represents a fish by an ideal pressure‐release surface having the exact size and shape as the swimbladder. ...
Geochemical cycling of silver in marine sediments along an offshore transect
Although there have been many surface water and water column silver (Ag) analyses in the ocean, the absence of high resolution pore water and solid phase Ag profiles has hampered our understanding of its oceanic geochemical ...
Insights into the phylogeny and coding potential of microbial dark matter
(Nature Publishing Group, 2013-07-14)
Genome sequencing enhances our understanding of the biological world by providing blueprints for the evolutionary and functional diversity that shapes the biosphere. However, microbial genomes that are currently available ...
Sound Cut, Record Number 9101301L
(Woods Hole Oceanographic Institution, 2003-06-10)
Recording of ten or more Fraser’s dolphins made by Ithaco 602M108 hydrophones, Ithaco 451 amplifiers, WHOI/PEMTEK tape recorder. Good clicks and whistles. Feeding at surface.
