      Solow, Andrew R.; Beet, Andrew R. (American Geophysical Union, 2008-10-09)
      A common problem in climate science is determining whether the pattern of variability in a particular process or variable has changed over time. When the modern observational record is short, this problem can be addressed ...

    • North Atlantic forcing of tropical Indian Ocean climate 

      Mohtadi, Mahyar; Prange, Matthias; Oppo, Delia W.; De Pol-Holz, Ricardo; Merkel, Ute; Zhang, Xiao; Steinke, Stephan; Luckge, Andreas (2014-02)
      The response of the tropical climate in the Indian Ocean realm to abrupt climate change events in the North Atlantic Ocean is contentious. Repositioning of the intertropical convergence zone is thought to have been responsible ...
    • North Atlantic ocean circulation and abrupt climate change during the last glaciation 

      Henry, L. Gene; McManus, Jerry F.; Curry, William B.; Roberts, Natalie L.; Piotrowski, Alexander M.; Keigwin, LLoyd (2016-05-21)
      The most recent ice age was characterized by rapid and hemispherically asynchronous climate oscillations, whose origin remains unresolved. Variations in oceanic meridional heat transport may contribute to these repeated ...
    • North Atlantic right whales (Eubalaena glacialis) ignore ships but respond to alerting stimuli 

      Nowacek, Douglas P.; Johnson, Mark P.; Tyack, Peter L. (Royal Society, 2003-12-03)
      North Atlantic right whales were extensively hunted during the whaling era and have not recovered. One of the primary factors inhibiting their recovery is anthropogenic mortality caused by ship strikes. To assess risk ...
    • North Atlantic salinity as a predictor of Sahel rainfall 

      Li, Laifang; Schmitt, Raymond W.; Ummenhofer, Caroline C.; Karnauskas, Kristopher B. (American Association for the Advancement of Science., 2016-05-06)
      Water evaporating from the ocean sustains precipitation on land. This ocean-to-land moisture transport leaves an imprint on sea surface salinity (SSS). Thus, the question arises of whether variations in SSS can provide ...
