Progress Report on Lidar for Lateral Mixing (LATMIX) Directed Research Initiative (DRI)
Abstract
The current work is a collaboration between J. Ledwell and E. Terray (WHOI), M. Sundermeyer (UMass Dartmouth), and B. Concannon (NAVAIR). We proposed to conduct a series of dye release experiments in the seasonal pycnocline and upper ocean to examine lateral dispersion and frontal processes on scales of 10 m to 10 km as part of the ONR ?Scalable Lateral Mixing and Coherent Turbulence? DRI. The vertical and horizontal dispersion and advection of the dye patches will be monitored on spatial scales of meters to several kilometers in the horizontal, 1-10 meters in the vertical, and on time scales of minutes to hours, up to 4 days. Sampling of the dye will be performed using airborne LIDAR, as well as in situ sensors lowered and towed from a ship. Additional measurements of optical characteristics, hydrography, currents, and internal wave characteristics will be used to identify particular driving mechanisms of the observed dispersion. The dye experiments will be coordinated with AUV and microstructure measurements proposed by other investigators to discern forcing mechanisms responsible for the dispersion. The dye experiments will also be guided by numerical modeling process studies proposed by other investigators under the DRI, and will provide data for testing such models.
