Summary of Field Work: |
The Louisiana-Texas shelf, site of significant freshwater effluent, intense seasonal thermal stratification, and one of the world’s largest hypoxia zones, provides an ideal study site. We will leverage an existing coastal meteorological platform location (LSU-CSI station 06) with mooring sites consisting of high spatial (0.5 m vertical) and temporal (< hourly) resolution temperature-conductivity sensors (MicroCAT’s) that will measure the upper ocean density structure and diurnally-resolved thermal variability. Collocated and mooring-bound high-frequency Acoustic Doppler Current Profilers' (ADCP's with wave/tide package) will provide a simultaneous high-resolution record of the current velocity profile in response to the recorded wind stress forcing. The central mooring will be located next to the CSI meteorological platform and in the midst of an array of similar such meteorological recording sites, whereas the remaining moorings will be configured around the site to account for tidal displacement and the horizontal covariance scales.
The central mooring will also be configured with the BioSonic Echosounder instrument; this provides a simultaneous record of mechanical mixing from breaking waves at the air-sea interface. We also propose to use the Vertical Microstructure Profiler (VMP) to measure vertical eddy diffusivities in the critical areas near-surface and at the buoyancy plume / oceanic water mass interface.
Field work will consist of mooring deployments, glider deployments, and
repeated transects using the SanFish towed platform. |
|
Summary of Facility Requirements: |
We require a research vessel to deploy moorings, gliders, and to deploy our SanFish-based sensors / A-frame / CTD rosette. Sufficient desk space, berthing for scientists / technicians. |
