Multi-sensor imaging and quantification of near-bottom turbulence in La Jolla Canyon
Abstract
Turbulence is central for a variety of Navy aims, including model improvement and battlespace characterization - yet, it is woefully, under sampled and poorly understood. We seek to simultaneously employ several new and old sensing modalities including distributed, temperature sensing (DTS), dye releases, bottom-mounted turbulence-measuring ADCPs, UUV microstructure/dye surveys, profiling dye-,and turbulence-measuring Wirewalkers, and rapid-repeated shipboard transects with microstructure and acoustic backscatter, in concer,t in order to image turbulent structures, their evolution and their fluxes in a fundamentally new way. The experiment will be sited, in La Jolla Canyon, greatly reducing complexity and cost because of the shallow depth and proximity to Scripps. These measurements, will enable a much better understanding of the time/space evolution of turbulent flows in the ocean, shed light on fundamental flui,d dynamics issues including diapycnal mass transport and exchange of fluid with the interior, and allow testing of standard 1-D assu,mptions typically made in microstructure measurements.This abstract is publicly releasable.
