    Brothers, Laura L.; Hart, Patrick E.; Ruppel, Carolyn D. (American Geophysical Union, 2012-08-07)
    Starting in Late Pleistocene time (~19 ka), sea level rise inundated coastal zones worldwide. On some parts of the present-day circum-Arctic continental shelf, this led to flooding and thawing of formerly subaerial permafrost ...

  • The minimum oxygen concentration in the western basin of the North Atlantic 

    Seiwell, Harry Richard (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1937-05)
    With the advance in knowledge of oceanic circulation there now exists a demand for additional identifying properties which will serve to trace the origin and movements of water masses in the sea, and to check earlier ...
  • Mitochondrial delivery is essential for synaptic potentiation 

    Tong, James Jiayuan (Marine Biological Laboratory, 2007-04)
    Mitochondria, as portable generators that power synaptic function, regulate the ATP supply and calcium homeostasis in the neuron. As molecular interactions within the synapses before and after the potentiation are beginning ...
  • Mitochondrial DNA sequence variation in North Atlantic long-finned pilot whales, Globicephala melas 

    Siemann, Liese A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-05)
    I sequenced mitochondrial DNA (mtDNA) from 59 long-finned pilot whales (Globicephala melas) that stranded on the coasts of Cape Cod, Newfoundland, Nova Scotia, Scotland, and England or were caught by commercial fisheries ...
  • Mitochondrial genomes of Clymenella torquata (Maldanidae) and Riftia pachyptila (Siboglinidae) : evidence for conserved gene order in Annelida 

    Jennings, Robert M.; Halanych, Kenneth M. (2004-10-04)
    Mitochondrial genomes are useful tools for inferring evolutionary history. However, many taxa are poorly represented by available data. Thus, to further understand the phylogenetic potential of complete mitochondrial ...
  • Mitochondrial genomics and Northwestern Atlantic population genetics of marine annelids 

    Jennings, Robert M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2005-09)
    The overarching goal of this thesis was to investigate marine benthic invertebrate phylogenetics and population genetics, focused on the phylum Annelida. Recent expansions of molecular methods and the increasing diversity ...
  • Mitochondrial respiration and Ca2+ waves are linked during fertilization and meiosis completion 

    Dumollard, Remi; Hammar, Katherine; Porterfield, D. Marshall; Smith, Peter J. S.; Cibert, Christian; Rouviere, Christian; Sardet, Christian (Company of Biologists Limited, 2003)
    Fertilization increases both cytosolic Ca2+ concentration and oxygen consumption in the egg but the relationship between these two phenomena remains largely obscure. We have measured mitochondrial oxygen consumption and ...
  • Mixing across the Arctic Ocean : microstructure observations during the Beringia 2005 Expedition 

    Rainville, Luc; Winsor, Peter (American Geophysical Union, 2008-04-30)
