Abstract:

Horizontal dispersion of momentum and scalar quantities by submesoscale processes in the ocean remains an under-studied topic. The physical forcings that potentially contribute to horizontal dispersion are many, such as, wind stress, frontal dynamics, river input and internal waves. Typically, regional numerical models use simple horizontal diffusion to parameterize the complex horizontal dispersion, producing variability at horizontal scales of 100 m to 1 km and time scales of hours to days. To improve model parameterization of horizontal dispersion, we need additional observations and a better understanding of the processes involved. The focus is on tasks that are intended to help in the planning of a larger coordinated effort. The specific components of the proposed research include 1 participation in a planning study group to develop a coordinated multi-year program. 2 testing of our dye tracking equipment and instrumentation and assessment of their condition.
