Dataset: In situ measurements of Oxygen, Temperature, and Salinity: Surface

This data are Argo floats deployed by the Emerson group at the University of Washington. The floats are standard Argo APEX floats with a variety of sensors in addition to those for pressure, temperature, and salinity.  Most of the data (from 46 floats that we call SOS-Argo floats) have an Aanderaa pO2 sensor (optode) installed on a 61 cm stalk above the end cap of the float, which allows the float to capture uncontaminated atmospheric pO2 for the purpose of in-situ calibration while the float is at the surface.  In addition to the SOS-Argo floats there are five equatorial floats with sensors for nitrate and pH in addition to a pO2 sensor on a stalk that is 10 cm high rather than the 61 cm on the SOS-Argo floats.  We refer to these floats as BGC Floats.  There are an additional six standard Argo floats.

Float data are organized into the different ocean basins in which they were deployed and the individual sensor data are listed along with the float serial number.  The data also appear on the University of Washington Google website (https://sites.google.com/a/uw.edu/sosargo/) along with maps of the float locations and preliminary sections and figures of selected data.  

Data archived here are: time, location, hydrostatic pressure, temperature, salinity, the partial pressure of O2 and occasionally nitrate and pH. This dataset contains the profile data (referred to as ####_output.csv at the University of Washington website).
