Abstract:

This dataset reports standard shipboard underway measurements from the R/V F.G. Walton Smith cruise WS16015 during the CARTHE LASER experiment in the Gulf of Mexico from 2016-01-15 to 2016-02-14. The data was collected during the CARTHE/LASER experiment which departed Miami, Florida on 2016-01-14, and returned 2016-02-16. This dataset reports temperature, pressure, depth, conductivity, salinity, precipitation, navigation, wind speed and direction, relative humidity, barometric pressure, meteorological data, turbidity, U- and V- current components, short and longwave radiation, and fluorometer readings. The cruise WS16015 was led by chief scientist Dr. Eric D’Asaro. Additional information about this cruise can be found in the R2R repository: http://www.rvdata.us/catalog/WS16015.

Purpose:

This data was collected to provide a continuous record of the RV position, heading and velocity during the entire LASER cruise. It also included meteorological data, hydrography and water velocity information. The purpose was to define the physical environment the ship was operating in during the experiment.
