Moored measurements of lee waves at West Mariana Ridge
Abstract
ABSTRACT Low frequency flows encountering rough topography lose both momentum and energy to a variety of poorly understood small-scale dynamical processes, including quasi-linear and strongly non-linear (hydraulic) internal lee wave generation. We propose to use two turbulencemeasuring moored profilers to better understand these processes as the North Equatorial Current and westward-propagating eddies impinge on the west Mariana Ridge. In a companion proposal we propose complementary towed ADCP/CTD measurements. The measurements will 1) characterize the near-ridge flows and their turbulence on timescales of hours to months, 2) improve parameterizations of drag and mixing (and therefore model representation) of eddies and currents over topography, and 3) support nearby studies with complementary scientific foci.
