ORCAS Medusa Flask Sampler Flask Data
https://data.eol.ucar.edu/dataset/490.019

Summary
The Medusa Flask Sampler flask data contains measurements of O2/N2, CO2, and
Ar/N2. The data were collected by the NSF/NCAR GV HIAPER (Gulfstream-V
High-performance Instrumented Airborne Platform for Environmental Research)
aircraft (Tail Number N677F) during the ORCAS (O2/N2 Ratio and CO2 Airborne
Southern Ocean Study) campaign.

Versions
  0.1
  1.0: Final release data.
  2.0: The AO2 and Medusa data sets have been updated to coincide with the
publication of Stephens et al., Atmospheric Measurement Techniques,
2021. For Medusa O2 data, this has included some additional flask
screening, updates to the Ar/N2 correction. For AO2 O2 data, this has
included more extensive QAQC and filtering updates, revisions to the
time-or-flight and mean offset corrections, and implementation of an
empirical ascent/descent correction, as described in the paper. For both
AO2 and Medusa, the O2 data have been updated for a span correction to
the SIO O2 Scale.
