  • Krishfield, Richard A.; Toole, John M.; Proshutinsky, Andrey; Timmermans, Mary-Louise (American Meteorological Society, 2008-11)
    An automated, easily deployed Ice-Tethered Profiler (ITP) instrument system, developed for deployment on perennial sea ice in the polar oceans to measure changes in upper ocean water properties in all seasons, is described, ...
  • Knapp, George P.; Stalcup, Marvel C.; Stanley, Robert J. (Woods Hole Oceanographic Institution, 1990-08)
    This report describes a newly developed automated Winkler titration system for dissolved oxygen in seawater which is presently in use at the Woods Hole Oceanographic Institution. This amperometric, calculated, endpoint ...
  • Knapp, George P.; Stalcup, Marvel C.; Stanley, Robert J. (Woods Hole Oceanographic Institution, 1990-08)

  • Ostermann, Dorinda R.; Karbott, Darrell; Curry, William B. (Woods Hole Oceanographic Institution, 1990-02)
    We have developd a computer controlled system to measure the calcium carbonate content of sediment samples. A menu driven program controls the analysis of each sample. The system first communicates with a Mettler digital ...
  • Yoerger, Dana R.; Bradley, Albert M.; Jakuba, Michael V.; German, Christopher R.; Shank, Timothy M.; Tivey, Maurice A. (Oceanography Society, 2007-03)
    Autonomous and remotely operated underwater vehicles play complementary roles in the discovery, exploration, and detailed study of hydrothermal vents. Beginning with clues provided by towed or lowered instruments, ...
  • Estapa, Margaret L.; Buesseler, Ken O.; Boss, Emmanuel S.; Gerbi, Gregory P. (Copernicus Publications on behalf of the European Geosciences Union, 2013-08-16)
    Observational gaps limit our understanding of particle flux attenuation through the upper mesopelagic because available measurements (sediment traps and radiochemical tracers) have limited temporal resolution, are ...
  • Sayles, Fred L.; Eck, Calvert F. (2009-04-13)
    The design and testing of a robotic analyzer for autonomous TCO2 measurement from oceanographic moorings is described. The analyzer employs a conductimetric method of TCO2 measurement wherein CO2 from an acidified sample ...
  • Taylor, Craig D.; Doherty, Kenneth W.; Molyneaux, Stephen J.; Morrison, Archie T.; Billings, John D.; Engstrom, Ivory B.; Pfitsch, Don W.; Honjo, Susumu (2006-01-11)
    An Autonomous Microbial Sampler (AMS) is described that will obtain uncontaminated and exogenous DNA-free microbial samples from most marine, fresh water and hydrothermal ecosystems. Sampling with the AMS may be conducted ...
  • Kunz, Clayton G. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-02)
    This thesis presents a system for automatically building 3-D optical and bathymetric maps of underwater terrain using autonomous robots. The maps that are built improve the state of the art in resolution by an order of ...
  • Huang, Rui Xin (Sears Foundation for Marine Research, 2005-01)
    It is shown that in the case with bottom topography, the available gravitational potential energy cannot be represented by the available pressure potential energy. Thus, a suitable quantity for the study of large-scale ...
  • Stanton, Timothy K.; Chu, Dezhang; Wiebe, Peter H.; Clay, Clarence S. (Acoustical Society of America, 1993-12)
    By heuristically extending the previously developed ray solution [Stanton et al. J. Acoust. Soc. Am. 94, 3454–3462 (1993)] to predict the scattering by cylinders over all angles of incidence, approximate expressions are ...
  • Foote, Kenneth G. (Acoustical Society of America, 1980-02)
    A general model for averaging the acoustic target strength functions of fish is stated in calculable form. It accounts for the influences of the distribution of generally coupled spatial and orientation states of fish, ...
  • Descamps, Sebastien; Jenouvrier, Stephanie; Gilchrist, H. Grant; Forbes, Mark R. (Public Library of Science, 2012-02-15)
    Evidence that infectious diseases cause wildlife population extirpation or extinction remains anecdotal and it is unclear whether the impacts of a pathogen at the individual level can scale up to population level so ...
  • Blacic, Tanya M.; Ito, Garrett T.; Shah, Anjana K.; Canales, J. Pablo; Lin, Jian (American Geophysical Union, 2008-12-04)
    The hot spot-influenced western Galápagos Spreading Center (GSC) has an axial topographic high that reaches heights of ∼700 m relative to seafloor depth ∼25 km from the axis. We investigate the cause of the unusual size ...
  • Blackman, Donna K.; Appelgate, B.; German, Christopher R.; Thurber, A. R.; Henig, A. S. (2012-06)
    Morphology of four spreading segments on the southern Chile Rise is described based on multi-beam bathymetric data collected along the axial zones. The distribution of axial volcanoes, the character of rift valley scarps, ...
  • Podar, Mircea; Mullineaux, Lauren S.; Huang, Hon-Ren; Perlman, Philip S.; Sogin, Mitchell L. (American Society for Microbiology, 2002-12)
    Group II introns are catalytic RNAs and mobile retrotransposable elements known to be present in the genomes of some nonmarine bacteria and eukaryotic organelles. Here we report the discovery of group II introns in a ...
  • Sanders, Robert W.; Gast, Rebecca J. (2011-11)
    Mixotrophy, the combination of phototrophy and heterotrophy within the same individual, is widespread in oceanic systems. Yet, neither the presence nor ecological impact of mixotrophs has been identified in an Arctic marine ...
  • Steele, John H.; Collie, Jeremy S.; Bisagni, James J.; Gifford, Dian J.; Fogarty, Michael J.; Link, Jason S.; Sullivan, B. K.; Sieracki, Michael E.; Beet, Andrew R.; Mountain, David G.; Durbin, Edward G.; Palka, D.; Stockhausen, W. T. (2007-05-09)
    Oceanographic regimes on the continental shelf display a great range in the time scales of physical exchange, biochemical processes and trophic transfers. The close surface-to-seabed physical coupling at intermediate scales ...
  • Riemenschneider, Ulrike; Sheremet, Vitalii A. (Cambridge University Press, 2006-09-15)
    Motivated by work on tilted convection (Sheremet, J. Fluid Mech., vol. 506, 2004, p. 217), a set of experiments is presented here using the same set-up of a tilted tank attached to a rotating centrifuge with a 2.5 m arm. ...
