    • Circulations and water mass balances in the Brazil Basin 

      Zhang, Huai-Min (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1991-09)
      Based on the Levitus atlas, we find that the application of the Montgomery streamfunction to the isopycnal surfaces induces an error which can not be ignored in some regions in the ocean. The error arises from the sloping ...

(American Meteorological Society, 2009-01)
      The Vasco—Cirene program ex-plores how strong air—sea inter-actions promoted by the shallow thermocline and high sea surface temperature in the Seychelles—Chagos thermocline ridge results in marked variability at synoptic, ...
    • Classification of broadband echoes from prey of a foraging Blainville's beaked whale

      Blainville's beaked whales (Mesoplodon densirostris) use broadband, ultrasonic echolocation signals with a −10 dB bandwidth from 26 to 51 kHz to search for, localize, and approach prey that generally consist of mid-water ...
    • Claus Prodehl and Walter D. Mooney : Exploring the earth’s crust: history and results of controlled-source seismology [Book review] 

      Stephen, Ralph A. (2014-04-03)
      Prodehl and Mooney have done an impressive service to the community in providing this compendium of controlled-­‐source seismic studies of the earth's crust carried out to 2005. It is a rema ...
    • Cleaning and pre-treatment procedures for biogenic and synthetic calcium carbonate powders for determination of elemental and boron isotopic compositions 

      Holcomb, Michael; DeCarlo, Thomas M.; Schoepf, Verena; Dissard, Delphine; Tanaka, Kiyoshi; McCulloch, Malcolm (2015-01)
      In preparing calcium carbonate samples for the measurement of various geochemical proxies, it is often necessary to remove contaminating phases while leaving the phase of interest altered as little as possible. Here we ...
    • The Cleft revealed: geologic, magnetic, and morphologic evidence for construction of upper oceanic crust along the southern Juan de Fuca Ridge 

      Stakes, Debra S.; Perfit, Michael R.; Tivey, Maurice A.; Caress, David W.; Ramirez, Tony M.; Maher, Norman (American Geophysical Union, 2006-04-12)
      The geology and structure of the Cleft Segment of the Southern Juan de Fuca Ridge (JdFR) have been examined using high-resolution mapping systems, observations by remotely operated vehicle (ROV), ROV-mounted magnetometer, ...
    • Clicking for calamari : toothed whales can echolocate squid Loligo pealeii 

      Madsen, Peter T.; Wilson, M.; Johnson, Mark P.; Hanlon, Roger T.; Bocconcelli, Alessandro; Aguilar De Soto, Natacha; Tyack, Peter L. (Inter-Research, 2007-11-27)
      Squid play an important role in biomass turnover in marine ecosystems and constitute a food source for ~90% of all echolocating toothed whale species. Nonetheless, it has been hypothesized that the soft bodies of squid ...
    • Clicking in shallow rivers : short-range echolocation of Irrawaddy and Ganges River dolphins in a shallow, acoustically complex habitat 

      Jensen, Frants H.; Rocco, Alice; Mansur, Rubaiyat M.; Smith, Brian D.; Janik, Vincent M.; Madsen, Peter T. (Public Library of Science, 2013-04-03)
      Toothed whales (Cetacea, odontoceti) use biosonar to navigate their environment and to find and catch prey. All studied toothed whale species have evolved highly directional, high-amplitude ultrasonic clicks suited for ...
    • Climate change as an intergenerational problem 

      Wunsch, Carl; Schmitt, Raymond W.; Baker, D. James (2012-11)
      Predicting climate change is a high priority for society, but such forecasts are notoriously uncertain. Why? Even should climate prove theoretically predictable---by no means certain---the near-absence of adequate ...
