Dataset: Marsh Pond temperature salinity and oxygen
Deployment: Plum_Island

Temperature, salinity, and oxygen saturation state data were collected using a YSI Exo2 water quality sonde, calibrated before and after each deployment, with no significant change in instrument response to any variable identified by pre and post calibration over the reported time periods, as well as good agreement with discrete subsampling of period using a handheld YSI ProODO temperature and oxygen saturation state sonde and salinity from a handheld refractometer. All temperature, salinity, and O2 saturation state uncertainties reported per manufacturer specifications. However, Environmental variability in temperature at locations around the pond was s.d. 1 degree C, and salinity was s.d. 0.5 on PSS-78. This environmental variability was used to determine the uncertainty in the saturation states for each noble gas in Datasheet 2. O2 saturation state varied locally around the pond, see Howard et al. (submitted, Limnol. Oceanogr. Letters). Ancillary meteorological data collected in close proximity to the sample data reported here is accessible from the LTER database (Giblin and Forbrich 2016; http://dx.doi.org/10.6073/pasta/14eb405f583ae2384b2c6c5714776214), and includes windspeed and atmospheric pressure.
