Inertial and Turbulent Processes in the Iceland Basin: A Proposal to the Near Inertial Shear and Kin
Abstract
Near-inertial waves (NIWs) are one of the most energetic modes of ocean variability, containing about half the kinetic energy in the, ocean at most sites (and even more underneath storm tracks). Hence, they are of central importance for a variety of ocean processes, including mixed layer (ML) deepening (Price et al., 1986), submesoscale statistics, larval dispersion and formation of thin layers,(Franks, 1995), restratification of MLs and thermohaline intrusions (Hosegood et al., 2008), and mixing of both the upper and deep o,cean (Hebert and Moum, 1994; Alford, 2003). Yet, an understanding of NIW energy sources and redistribution by wave radiation is lack,ing, causing NIWs to be poorly represented in regional and global models.We propose observational and numerical studies of inertial,forcing of upper ocean fronts at scales ranging from the geostrophic to ageostrophic. High Rossby number fronts can impose lateral v,ariability that will modify the partitioning between a) local trapping of near-inertial disturbances, their projection into high mod,es and dissipation versus b) the portion of the near-inertial input that that is organized into low modes that radiate far from the,storm-generation region.
