Abstract:

Moving Vessel Profiler (MVP) CTD casts were part of the Lagrangian Submesoscale Experiment (LASER) conducted in the northern Gulf of Mexico January-February 2016 (2016-01-20 - 2016-02-12) from aboard the R/V Walton Smith (WS16015). Data include depth/cast grids of temperature, conductivity, and pressure, with salinity and sigma_theta derived quantities. Raw data were gridded onto 1-m vertical bins. Data were further subdivided into 9 "Surveys", with one netcdf file per survey. (W

Purpose:

To map water features in the Gulf of Mexico. Most surveys concentrated on the strong cold-fresh fronts advected off the shelf and into the interior.

Data Parameters and Units:

Pressure (dbar), Temperature (deg C), Conductivity (mS/cm), Practical Salinity (psu), Sigma_theta (potential density -1000) (kg/m^3), Analog (volt), Latitude (degrees North), Longitude (degrees East), Time (days since 2016-01-01), Cast number, Depth (m)

Methods:

16 Hz data has been binned into 1-m depth bins. Only downcasts have been used. Raw data available from jklymak@uvic.ca
