  • Gene discovery and expression profilng in the toxin-producing marine diatom, Pseudo-nitzschia multiseries (Hasle) Hasle 

    Boissonneault, Katie Rose (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2004-09)
    Toxic algae are a growing concern in the marine environment. One unique marine diatom, Pseudo-nitzschia multiseries (Hasle) Hasle, produces the the neurotoxin domoic acid, which is the cause of amnesic shellfish poisoning. ...
  • Gene expression in American lobster (Homarus americanus) with epizootic shell disease 

    Tarrant, Ann M.; Franks, Diana G.; Verslycke, Tim A. (National Shellfisheries Association, 2012-06)
    Epizootic shell disease (ESD) has been reported widely in American lobster (Homarus americanus, Milne Edwards) in southern New England. The appearance of irregular, deep lesions—characteristic of ESD—has been associated ...
  • Gene expression in the deep biosphere 

    Orsi, William D.; Edgcomb, Virginia P.; Christman, Glenn D.; Biddle, Jennifer F. (2013-04-23)
    Scientific ocean drilling has revealed a deep biosphere of widespread microbial life in sub-seafloor sediment. Microbial metabolism in the marine subsurface likely plays an important role in global biogeochemical cycles1-3 ...
  • Genealogical analyses of multiple loci of litostomatean ciliates (Protista, Ciliophora, Litostomatea) 

    Vd’acny, Peter; Bourland, William A.; Orsi, William D.; Epstein, Slava S.; Foissner, Wilhelm (Elsevier, 2012-07-09)
    The class Litostomatea is a highly diverse ciliate taxon comprising hundreds of free-living and endocommensal species. However, their traditional morphology-based classification conflicts with 18S rRNA gene phylogenies ...
  • The general circulation of the atmosphere : 2000 program in Geophysical Fluid Dynamics 

    Salmon, Rick; Held, Issac M.; Fields, Janet; Thiffeault, Jean-Luc (Woods Hole Oceanographic Institution, 2001-03)
    In its millenial session, the GFD program focused on "The General Circulation of the Atmosphere." Isaac Held led the charge with an inspiring two-week introductory course, strongly supported by the lectures of Alan Plumb, ...
  • A general inversion for end-member ratios in binary mixing systems 

    Sohn, Robert A. (American Geophysical Union, 2005-11-15)
    Binary mixing is one of the most common models used to explain variations in geochemical data. When the data being modeled are ratios of elements or isotopes, the mixtures follow hyperbolic trends with curvatures that ...
  • A generalized baleen whale call detection and classification system 

    Baumgartner, Mark F.; Mussoline, Sarah E. (Acoustical Society of America, 2011-05)
    Passive acoustic monitoring allows the assessment of marine mammal occurrence and distribution at greater temporal and spatial scales than is now possible with traditional visual surveys. However, the large volume of ...
  • Generalized concentration addition predicts joint effects of aryl hydrocarbon receptor agonists with partial agonists and cCompetitive antagonists 

    Howard, Gregory J.; Schlezinger, Jennifer J.; Hahn, Mark E.; Webster, Thomas F. (National Institute of Environmental Health Sciences, 2009-12-22)
    Background: Predicting the expected outcome of a combination exposure is critical to risk -assessment. The toxic equivalency factor (TEF) approach used for analyzing joint effects of dioxin-like chemicals is a special case ...
  • Generalized conditions for hydraulic criticality of oceanic overflows 

    Pratt, Lawrence J.; Helfrich, Karl R. (American Meteorological Society, 2005-10)
