      Meyer, Amelie; Polzin, Kurt L.; Sloyan, Bernadette M.; Phillips, Helen E. (American Meteorological Society, 2015-12-07)
      In the stratified ocean, turbulent mixing is primarily attributed to the breaking of internal waves. As such, internal waves provide a link between large-scale forcing and small-scale mixing. The internal wave field north ...

    • Interplay between the Indonesian Throughflow and the Luzon Strait Throughflow 

      Liu, Qinyan; Huang, Rui Xin; Wang, Dong Xiao; Xie, Qiang; Huang, Qizhou (2006)
      Analysis based on the “Island Rule” and ocean assimilation dataset shows that the interannual variability of the Indonesian Throughflow and the Luzon Strait (South China Sea) Throughflow is out of phase. Wind anomaly in ...
    • Interpretation of equatorial current meter data as internal waves 

      Blumenthal, Martin Benno (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-01)
      Garrett and Munk use linear dynamics to synthesize frequency-wavenumber energy spectra for internal waves (GM72, GM75, GM79). The GM internal wave models are horizontally isotropic, vertically symmetric, purely propagating, ...
    • Intraseasonal variability near 10°N in the eastern tropical Pacific Ocean

      New in situ observations from 10°N, 125°W during 1997–1998 show strong intraseasonal variability in meridional velocity and sea surface temperature. The 50- to 100-day oscillations in sea surface height (SSH) have long ...
    • Introduction to special section : U.S. GLOBEC : physical processes on Georges Bank (GLOBEC) 

      Beardsley, Robert C.; Smith, Peter C.; Lee, Craig M. (American Geophysical Union, 2003-11-18)
    • An introduction to the special issue on internal waves 

      St. Laurent, Louis C.; Alford, Matthew H.; Paluszkiewicz, Terri (The Oceanography Society, 2012-06)
      This special issue of Oceanography presents a survey of recent work on internal waves in the ocean. The undersea analogue to the surface waves we see breaking on beaches, internal waves play an important role in transferring ...
    • An inverse approach to understanding benthic oxygen isotope records from the last deglaciation 

      Amrhein, Daniel E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2014-02)
      Observations suggest that during the last deglaciation (roughly 20,000-10,000 years ago) the Earth warmed substantially, global sea level rose approximately 100 meters in response to melting ice sheets and glaciers, and ...
