The analytic solution is benchmarked against data collected in an experiment performed at the Naval Research Laboratory [Collis et al., J. Acoust. Soc. Am. 122, 1987\u20131993 (2007)]. Comparisons reveal a close match between the analytic solution and experimental data. Results are strongly dependent on the accuracy of the horizontal wavenumbers for the modes, and horizontal wavenumber spectra are compared against those from the experimental data.<\/jats:p>","DOI":"10.1121\/1.4740227","type":"journal-article","created":{"date-parts":[[2012,8,7]],"date-time":"2012-08-07T18:00:41Z","timestamp":1344362441000},"page":"EL182-EL188","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":14,"title":["Elastic Pekeris waveguide normal mode solution comparisons against laboratory data"],"prefix":"10.1121","volume":"132","author":[{"given":"Joseph D.","family":"Schneiderwind","sequence":"first","affiliation":[{"name":"CINTAL, Centro de Investiga\u00e7\u00e3o Tecnol\u00f3gica do Algarve , University do Algarve, Campus de Gambelas 8005-139 Faro, jdschneiderwind@gmail.com","place":["Portugal"]}]},{"given":"Jon M.","family":"Collis","sequence":"additional","affiliation":[{"name":"Department of Applied Mathematics and Statistics, Colorado School of Mines, Golden , Colorado 80401 jcollis@mines.edu"}]},{"given":"Harry J.","family":"Simpson","sequence":"additional","affiliation":[{"name":"Physical Acoustic Branch Code 7136, Naval Research Laboratory , 4555 Overlook Avenue, SW, Washington DC 20375 harry.simpson@nrl.navy.mil"}]}],"member":"231","published-online":{"date-parts":[[2012,8,7]]},"reference":[{"key":"2025080716114148600_c1","doi-asserted-by":"crossref","first-page":"3631","DOI":"10.1121\/1.417226","article-title":"A normal mode model for acousto-elastic ocean environments","volume":"100","year":"1996","journal-title":"J.
