Each Wire Flyer dive profiles over a 400-m depth range between 0-800 m in the water column. Transects span between 30-120 km over a duration of 5-20 hours. Four files are associated with each Wire Flyer dive: one file with all measured quantities interpolated to the same timestamp (all_4_Hz) and one for each sensor recording data (ecopuck, optode, and CTD). The all_4_Hz.csv files are the best version of the data after processing, while the csv files for each sensor contain raw data. For more information on the Wire Flyer, see Roman et al. (2019). Data are in CSV format. Time is in seconds since January 1, 1970, 00:00:00 UTC (unix timestamp). This dataset is available to the public for a wide variety of uses including scientific research and analysis.

Parameter or Variable: SALINITY (calculated); Units: psu; Observation Category: in situ; Sampling Instrument: Sea-Bird 49 FastCAT Conductivity, Temperature, Depth; Sampling and Analyzing Method: In *_sbe49.csv: Raw salinity data calculated from conductivity, temperature, and pressure with the TEOS-10 toolbox (McDougall and Barker, 2011); Data Quality Method: In *_all_4_Hz.csv: To correct for salinity spiking, the conductivity data are smoothed over a window of 21 data points (~2 m) to account for thermal lag of the temperature sensor. The upcasts have significantly more spiking at the base of the mixed layer compared to downcasts due to the Wire Flyer's upward vertical speed being ~1 m/s faster than its downward speed at the top of its profiling depth range. Hence, an additional correction was made to the upcasts, allowing conductivity to be shifted in depth relative to temperature to account for the time lag associated with a parcel of water traveling between the temperature and conductivity sensors. Parameter or Variable: CONDUCTIVITY (measured); Units: siemens per meter; Observation Category: in situ; Sampling Instrument: Sea-Bird 49 FastCAT Conductivity, Temperature, Depth; Sampling and Analyzing Method: In *_sbe49.csv: Raw conductivity measured by the CTD; Data Quality Method: In *_all_4_Hz.csv: A temporal offset of O(1) s is applied to the data to account for a minor measurement lag due to the vehicle profiling up and down.

Per recommendation by the Aandeera optode manual (https://www.aanderaa.com/media/pdfs/oxygen-optode-4330-4835-and-4831.pdf), a salinity and pressure correction are made to the oxygen data.
