Description:
The cascade from tides to turbulence has been hypothesized to serve as a major energy pathway for ocean mixing. We investigated this cascade along the Hawaiian Ridge using observations and numerical models. A divergence of internal tidal energy flux observed at the ridge agrees with the predictions of internal tide models. Large internal tidal waves with peak-to-peak amplitudes of up to 300 meters occur on the ridge. Internal-wave energy is enhanced, and turbulent dissipation in the region near the ridge is 10 times larger than open-ocean values. Given these major elements in the tides-to-turbulence cascade, an energy budget approaches closure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rudnick, Daniel L -- Boyd, Timothy J -- Brainard, Russell E -- Carter, Glenn S -- Egbert, Gary D -- Gregg, Michael C -- Holloway, Peter E -- Klymak, Jody M -- Kunze, Eric -- Lee, Craig M -- Levine, Murray D -- Luther, Douglas S -- Martin, Joseph P -- Merrifield, Mark A -- Moum, James N -- Nash, Jonathan D -- Pinkel, Robert -- Rainville, Luc -- Sanford, Thomas B -- New York, N.Y. -- Science. 2003 Jul 18;301(5631):355-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Institution of Oceanography, La Jolla, CA 92093-0213, USA. drudnick@ucsd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12869758" target="_blank"〉PubMed〈/a〉
