Subtropical Shelf Front cruise - Thermosalinograph data

This dataset contains the near-surface ocean (nominally 3 m depth) temperature and salinity observations collected during the Subtropical Shelf Front Cruise (PD_2013_04) carried out on board the research Vessel Puerto Deseado from 3 to 10 October 2013. A SeaBird Electronics SBE 21 thermosalinograph, which recorded data every 30 seconds, was used throughout the cruise. Data records in physical units are reported in an ascii text file. The variables are presented in the following order, with missing values indicated by "-9.990e-29": Julian Day Latitude [deg] Longitude [deg] Pressure [dbar] Temperature [ITS-90, deg C] Conductivity [S/m] Salinity, Practical [PSU] Sigma-t [kg/m^3] Data were calibrated and quality controlled at the Servicio de Hidrografía Naval, Argentina ([e-mail]). A readme.txt file containing this description is also included.
