Summary of Field Work: |
We will quantify the influence of turbulence generated at the seafloor boundary layer on vertical mixing and stratification in shallow water outside the surf zone.
This work will be performed over two years. During the first year we will perform a pilot experiment to characterize the field site and take baseline measurements. The pilot deployment cruise will deploy two quadpods (large instrumented frame) and 9 ADCP moorings while performing bathymetric surveying and making CTD casts. The instruments need to be recovered during a retrieval cruise 4-10 weeks later.
In the second year, we will also perform a pair of cruises one for deployment and one for retrieval at the field site. We will deploy a cross-shore array (no deeper than 50 m) consisting of two quadpods and and a third smaller mooring. The instruments will remain in the water for 4-6 weeks before recovery. We will perform bathymetric surveying and CTD casts of the field site during both the deployment and recovery cruises. All work is planned to be performed in shallow water offshore of Pt. Sal. |
|
Summary of Facility Requirements: |
We will need CTD/rosette, ADCP, bathymetric system, and sufficient deck space to stage and deploy/retrieve large quadpod (3 m square base and 2.3 m height) through the A-frame. We will supply our own line for deployment to use with ship wench. Ship crane for loading. We want to perform bathymetric surveying with ship system and hopefully our own multi beam system - need to discuss options for mounting. |
