Abstract

Comparison of four recent field experiments with similar type of historical measurements was performed to determine whether internal wave energy has increased with the decline of the Arctic sea ice. The internal wave energy was calculated on the basis of frequency spectrum inferred from ice tethered SBE37 CTD at three levels within the halocline while the Russian ice camp drifted through the Amundsen Basin of the Arctic Ocean in April of 2007, 2009, 2010, and 2012. The results of modern measurements with a total duration of more than 40 days are compared with 14 experiments performed in the Arctic in the period from 1966 to 1989, whose total measurement duration was about 180 days. Comparisons reanalyzed using the same method reveal no trend evident over the 40 year period in spite of the drastic decline of the sea ice.
