Ocean Dynamics

Abstract

LONG-TERM GOAL. To gain a more complete understanding of ocean dynamical processes, particularly at fine-scale, through intercomparison of high, mid- and low-latitude observations, both near the sea surface, in the main thermocline, and near the sea floor. OBJECTIVES. To compare fine and internal wave scale measurements from equatorial, mid-latitude and Arctic observations. To quantify the relationship between fine-scale background conditions and the occurrence of microscale breaking. APPROACH. Progress is effected through a steady-state cycle of instrument development, field observation and data analysis. The primary instruments employed include Doppler sonar and profiling CTD's. Generically, our instruments produce information which is quasi-continuous in space and time. Measurements typically span two decades in the wavenumber domain. This broad band space-time coverage enables the investigation of interactions which span space and time scales.
