    • Destructive changes in the neuronal structure of the FVB/N mouse retina 

      Yang, Jinnan; Nan, ChangLong; Ripps, Harris; Shen, Wen (Public Library of Science, 2015-06-19)
      We applied a series of selective antibodies for labeling the various cell types in the mammalian retina. These were used to identify the progressive loss of neurons in the FVB/N mouse, a model of early onset retinal ...

      Karson, J. A.; Fruh-Green, G. L.; Kelley, Deborah S.; Williams, E. A.; Yoerger, Dana R.; Jakuba, Michael V. (American Geophysical Union, 2006-06-21)
      Near-bottom investigations of the cross section of the Atlantis Massif exposed in a major tectonic escarpment provide an unprecedented view of the internal structure of the footwall domain of this oceanic core complex. ...
    • A detailed geochemical study of island arc crust : the Talkeetna Arc section, south–central Alaska

      The Early to Middle Jurassic Talkeetna Arc section exposed in the Chugach Mountains of south central Alaska is 5-18 km wide and extends for over 150 km. This accreted island arc includes exposures of upper mantle to ...
    • Detailed studies of the structure, tectonics, near bottom magnetic anomalies and microearthquake seismicity of the Mid-Atlantic Ridge near 37°N 

      Macdonald, Ken C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-09)
      The Mid-Atlantic Ridge is one of the most well known and yet poorly understood spreading centers in the world. A detailed investigation of the Mid-Atlantic Ridge crest near 37°N (FAMOUS) was conducted using a deeply towed ...
    • Detectability of CO2 flux signals by a space-based lidar mission 

      Hammerling, Dorit M.; Kawa, S. Randolph; Schaefer, Kevin; Doney, Scott C.; Michalak, Anna M. (John Wiley & Sons, 2015-03-11)
      Satellite observations of carbon dioxide (CO2) offer novel and distinctive opportunities for improving our quantitative understanding of the carbon cycle. Prospective observations include those from space-based lidar such ...
    • Detecting anthropogenic CO2 changes in the interior Atlantic Ocean between 1989 and 2005 

      Wanninkhof, Rik; Doney, Scott C.; Bullister, John L.; Levine, Naomi M.; Warner, Mark J.; Gruber, Nicolas (American Geophysical Union, 2010-11-30)
