  • Habitat associations in gastropod species at East Pacific Rise hydrothermal vents (9°50'N) 

    Mills, Susan W.; Mullineaux, Lauren S.; Tyler, Paul A. (Marine Biological Laboratory, 2007-06)
    At deep-sea hydrothermal vents on the East Pacific Rise (9°50'N), distinct megafaunal assemblages are positioned along strong thermal and chemical gradients. We investigated the distribution of gastropod species to determine ...
  • Habitat associations of juvenile versus adult butterflyfishes 

    Pratchett, Morgan S.; Berumen, Michael L.; Marnane, M. J.; Eagle, J. V.; Pratchett, D. J. (2007-10)
    Many coral reef fishes exhibit distinct ontogenetic shifts in habitat use while some species settle directly in adult habitats, but there is not any general explanation to account for these differences in settlement ...
  • Habitat damage, marine reserves, and the value of spatial management 

    Moeller, Holly V.; Neubert, Michael G. (Ecological Society of America, 2013-07)
    The biological benefits of marine reserves have garnered favor in the conservation community, but “no-take” reserve implementation is complicated by the economic interests of fishery stakeholders. There are now a number ...
  • Halocline structure in the Canada Basin of the Arctic Ocean 

    Shimada, Koji; Itoh, Motoyo; Nishino, Shigeto; McLaughlin, Fiona A.; Carmack, Eddy C.; Proshutinsky, Andrey (American Geophysical Union, 2005-02-05)
    We examine the varieties and spatial distributions of Pacific and Eastern Arctic origin halocline waters in the Canada Basin using 2002–2003 hydrographic data. The halocline structure in the Canada Basin is different from ...
  • Halogenated 1'-methyl-1,2'-bipyrroles (MBPs) in the northwestern Atlantic 

    Pangallo, Kristin C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-09)
    Halogenated 1’-methyl-1,2’-bipyrroles (MBPs) are a distinctive class of marine organic compounds. They are naturally produced, they have a unique carbon structure, they are highly halogenated, and they bioaccumulate in ...
  • Halogenated organic compounds in archived whale oil : a pre-industrial record 

    Teuten, Emma L.; Reddy, Christopher M. (2006-07-24)
    To provide additional evidence that several halogenated organic compounds (HOCs) found in environmental samples are natural and not industrially produced, we analyzed an archived whale oil sample collected in 1921 from the ...
  • Hand tools and mechanical accessories for a deep submersible 

    Winget, Clifford L. (Woods Hole Oceanographic Institution, 1969-05)
    This report presents the design and construction details for various mechanical hand tools and accessories used by a manned deep submersible. The tools require the use of a mechanical manipulator, and were designed specifically ...
  • Handbook of oceanographic engineering materials : volume I - metals and alloys 

    Dexter, Stephen C. (Woods Hole Oceanographic Institution, 1972-12)
    This handbook is intended to serve as an aid in materials selection to Oceanographic engineers and designers. As such it is intentionally limited to materials that may be used advantageously in the marine environment.
  • Hard and soft anatomy in two genera of Dondersiidae (Mollusca, Aplacophora, Solenogastres) 

    Scheltema, Amelie H.; Schander, Christoffer; Kocot, Kevin M. (Marine Biological Laboratory, 2012-06-01)
    Phylogenetic relationships and identifications in the aplacophoran taxon Solenogastres (Neomeniomorpha) are in flux largely because descriptions of hard parts––sclerites, radulae, copulatory spicules––and body shape have ...
  • Harmful algal blooms and eutrophication : examining linkages from selected coastal regions of the United States 

    Anderson, Donald M.; Burkholder, JoAnn M.; Cochlan, William P.; Glibert, Patricia M.; Gobler, Christopher J.; Heil, Cynthia A.; Kudela, Raphael M.; Parsons, Michael L.; Rensel, J. E. Jack; Townsend, David W.; Trainer, Vera L.; Vargo, Gabriel A. (2008-07-28)
    Coastal waters of the United States (U.S.) are subject to many of the major harmful algal bloom (HAB) poisoning syndromes and impacts. These include paralytic shellfish poisoning (PSP), neurotoxic shellfish poisoning ...
  • Harmonic analysis of the cone flicker ERG of rabbit 

    Qian, Haohua; Alexander, Kenneth R.; Ripps, Harris (Elsevier B.V., 2010-10-23)
    Harmonic analysis was used to characterize the rabbit flicker ERG elicited by sinusoidally modulated full-field stimuli under light-adapted conditions. The frequency-response function for fundamental amplitude, derived ...
  • The harmonic interval : fact or artifact in spectral analysis of pulse trains 

    Watkins, William A. (Woods Hole Oceanographic Institution, 1968-03)
    The harmonic interval indicated during spectrographic analysis of a rapid train of pulses may be used to determine the pulse repetition-rate. If the pulse rate is regular, but too rapid to be separated, the repetition-rate ...
  • HARRNESS : a framework for HAB research and monitoring in the United States for the next decade 

    Anderson, Donald M.; Ramsdell, John S. (Oceanography Society, 2005-06)
    More than a decade ago, the U.S. approach to research on harmful algal blooms (HABs) was uncoordinated and modest in scale. Research groups were few and their work was piecemeal and constrained by small budgets that ...
  • Hearing abilities and sound reception of broadband sounds in an adult Risso’s dolphin (Grampus griseus ) 

    Mooney, T. Aran; Yang, Wei-Cheng; Yu, Hsin-Yi; Ketten, Darlene R.; Jen, I-Fan (2015-04)
    While odontocetes do not have an external pinna that guides sound to the middle ear, they are considered to receive sound through specialized regions of the head and lower jaw. Yet odontocetes differ in the shape of the ...
  • Hearing in cetaceans : from natural history to experimental biology 

    Mooney, T. Aran; Yamato, Maya; Branstetter, Brian K. (2012-02)
    Sound is the primary sensory cue for most marine mammals, and this is especially true for cetaceans. To passively and actively acquire information about their environment, cetaceans have perhaps the most derived ears of ...
  • Hearing pathways in the Yangtze finless porpoise, Neophocaena asiaeorientalis asiaeorientalis 

    Mooney, T. Aran; Li, Songhai; Ketten, Darlene R.; Wang, Kexiong; Wang, Ding (Company of Biologists, 2013-10-18)
    How an animal receives sound may influence its use of sound. While ‘jaw hearing’ is well supported for odontocetes, work examining how sound is received across the head has been limited to a few representative species. The ...
  • Heat and freshwater transport through the central Labrador Sea 

    Straneo, Fiamma (American Meteorological Society, 2006-04)
    The seasonal and interannual variations in the export of Labrador Sea Water (LSW), and in the heat and freshwater transport through the central Labrador Sea, are examined for two different periods: from 1964 to 1974, using ...
  • Heat and salinity budgets at the Stratus mooring in the southeast Pacific 

    Holte, James W.; Straneo, Fiamma; Farrar, J. Thomas; Weller, Robert A. (John Wiley & Sons, 2014-11-28)
    The surface layer of the southeast Pacific Ocean (SEP) requires an input of cold, fresh water to balance heat gain, and evaporation from air-sea fluxes. Models typically fail to reproduce the cool sea surface temperatures ...
