    • 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 ...
    • Heat and salt balances over the New England continental shelf, August 1996 to June 1997 

      Lentz, Steven J.; Shearman, R. Kipp; Plueddemann, Albert J. (American Geophysical Union, 2010-07-29)
      Heat and salt balances over the New England shelf are examined using 10 month time series of currents, temperature, and salinity from a four element moored array and surface heat and freshwater fluxes from a meteorological ...
    • Heat content of the Arabian Sea Mini Warm Pool is increasing 

      Nagamani, P. V.; Ali, M. M.; Goni, Gustavo J.; Udaya Bhaskar, T. V. S.; McCreary, Julian P.; Weller, Robert A.; Rajeevan, Madhavan Nair; Gopalakrishna, V. V.; Pezzullo, John C. (John Wiley & Sons, 2015-11-18)
      Sea surface temperature in the Arabian Sea Mini Warm Pool has been suggested to be one of the factors that affects the Indian summer monsoon. In this paper, we analyze the annual ocean heat content (OHC) of this region ...
    • Heat flow and tectonics of the Ligurian Sea basin and margins 

      Jemsek, John P. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-05)
      Heat flow, tectonic subsidence and crustal thickness distributions in the Ligurian Basin are best explained by asymmetric lithospheric thinning mechanisms. Over 150 heat flow measurements are made on several transects ...
    • Heat flow variations on a slowly accreting ridge : constraints on the hydrothermal and conductive cooling for the Lucky Strike segment (Mid-Atlantic Ridge, 37°N) 

      Lucazeau, Francis; Bonneville, Alain; Escartin, Javier E.; von Herzen, Richard P.; Gouze, Philippe; Carton, Helene; Cannat, Mathilde; Vidal, Valerie; Adam, Claudia (American Geophysical Union, 2006-07-27)
      We report 157 closely spaced heat flow measurements along the Lucky Strike segment in the Mid-Atlantic Ridge (MAR) for ages of the ocean floor between 0 and 11 Ma. On the eastern flank of a volcanic plateau delimiting ...
    • Heat loss and hydrothermal circulation due to sea-floor spreading 

      Williams, David Lee (Woods Hole Oceanographic Institution, 1974-07)
      Lithospheric cooling along the Galapagos Spreading Center at 86°W longitude, as determined by surface heat-flow measurements, appears dominated by hydrothermal circulation. This same phenomena apparently exists on the ...
    • Heat shock protein expression during stress and diapause in the marine copepod Calanus finmarchicus 

      Aruda, Amalia M.; Baumgartner, Mark F.; Reitzel, Adam M.; Tarrant, Ann M. (2011-03)
      Calanoid copepods, such as Calanus finmarchicus, are a key component of marine food webs. C. finmarchicus undergoes a facultative diapause during juvenile development, which profoundly affects their seasonal distribution ...
    • Heat, salt, and freshwater budgets for a glacial fjord in Greenland 

      Jackson, Rebecca H.; Straneo, Fiamma (American Meteorological Society, 2016-09-01)
      In Greenland’s glacial fjords, heat and freshwater are exchanged between glaciers and the ocean. Submarine melting of glaciers has been implicated as a potential trigger for recent glacier acceleration, and observations ...
    • Heave and roll response of free floating bodies of cylindrical shape 

      Berteaux, Henri O.; Goldsmith, Roger A.; Schott, W. E. (Woods Hole Oceanographic Institution, 1977-02)
      The following report describes a computer solution to help predict the heave and roll response of free floating bodies of cylindrical shape when excited by random seas with known spectra. The basic concepts of harmonic ...
    • Heaving modes in the world oceans 

      Huang, Rui Xin (Springer, 2015-03-19)
      Part of climate changes on decadal time scales can be interpreted as the result of adiabatic motions associated with the adjustment of wind-driven circulation, i.e., the heaving of the isopycnal surfaces. Heat content ...
    • Heightened hurricane surge risk in northwest Florida revealed from climatological-hydrodynamic modeling and paleorecord reconstruction 

      Lin, Ning; Lane, D. Philip; Emanuel, Kerry A.; Sullivan, Richard M.; Donnelly, Jeffrey P. (John Wiley & Sons, 2014-07-21)
      Historical tropical cyclone (TC) and storm surge records are often too limited to quantify the risk to local populations. Paleohurricane sediment records uncover long-term TC activity, but interpreting these records can ...
    • Helium and lead isotope geochemistry of oceanic volcanic rocks from the East Pacific and South Atlantic 

      Graham, David W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-09)
      The isotopic evolution of helium and lead in the Earth is coupled by virtue of their common radioactive parents uranium and thorium. The isotopic signatures in oceanic volcanic rocks provide constraints on the temporal ...
