Characterize acoustic environment in a submarine canyon
Abstract
Approved for Public ReleaseThe project is to study the underwater acoustic environment of the Kao-Ping Submarine Canyon (KPSC) in southwest Taiwan. The goal is to statistically understand and describe the underwater environment in temporal, spatial, and spectral scales and investigate the changes in the sound environment in various significant events, such as high wind (typhoons) and hyperpycnal flows (sediment flows). The methodology is to deploy subsurface moorings, conduct shipboard surveys and collect ancillary data in KPSC. The passive acoustic ambient noises data will be collected using high-frequency line array mooring and single hydrophone recorders. The ancillary data will be collected using turbidity sensors and Acoustic Doppler Current Profiler (ADCP) with echo intensity and shipboard survey. The meteorology data will be collected from the surface weather buoy nearby. Year 1 is the pilot study period to deploy a test buoy for one month and plan the field experiment. Year 2 and Year 3 are the field works period to deploy acousticmooring for three months and refine the fieldwork plan, and Year 4 is to review and synthesize the results.
