Waves, Langmuir Cells, and the Upper Ocean Boundary Layer DRI

Abstract

Measurements and modeling of the upper ocean boundary layer were conducted with the goal of developing improved understanding and models of this region. Total of 17 floats and surface autonomous platforms were deployed in a field experiment during March and April 2017 near Catalina Island California. A series of wind bursts resulted in multiple episodes of mixed layer deepening suitable for studying this problem. Data from the multiple platforms was in intercalibrated and extensive analysis undertaken to understand and compare the variety of different velocity measurements made including a detailed analysis of the motion of Lagrangian floats forced by surface waves. Modeling efforts resulted in new formulations of large eddy simulations, closures summarizing these simulations and suitable for use in larger-scale models, and a community-wide inter-comparison of such models.
