Summary of Field Work: |
We are proposing a field program in the Gulf of Mexico to study interaction between submesoscale eddies and near inertial oscillations (NIOs), consisting of two 3-week intensive observational periods, using two research vessels and multiple autonomous surface vehicles (ASVs). We will conduct repeated, approximately 4 day-long coordinated surveys following an array of drifters and dye, as well as some coordinated surveys in a geographically fixed pattern. We will sample features using profiling CTDs, microsctructure profilers, temperature chains, drifters, fluorescent dye, bottom landers and ASVs. |
|
Summary of Facility Requirements: |
We will require two research vessels capable of rapidlly surveying submesoscale features over the shelf in the Gulf of Mexico. We will bring profiling CTDs, microstructure profilers, temperature chains, drifters, bottom landers, fluorescent dye, ASVs and water column imaging echosounders. We will need research vessel meteorological observations (winds, air-sea temps, relative humidity, long and short wave radiative heat flux), flow through system (temperature and salinity), and ADCPs capable of profiling in shallow water 20 m. |
