High-resolution measurements of salinity, temperature, and partial pressure of carbon dioxide (pCO2) taken at Whiskey Creek Shellfish Hatchery, Netarts Bay, Oregon, from 2014 - 2019 are provided in this data set. Briefly, a permanently submerged pipe draws in bay water to supply the shellfish hatchery tanks. Unmodified water is branched into an adjacent laboratory where determination of salinity and temperature are measured using a SeaBird Electronics 45 MicroTSG (SBE45) at a rate of approximately 1 Hz. Incoming water passes through the TSG and immediately into a modified enclosed-headspace shower-head equilibration chamber. Water flows over a porous bubbler tube where the recirculated headspace gas is introduced into the equilibration chamber. High water flow rates and vigorous bubbling ensures complete equilibration of the headspace gas CO2 with the dissolved CO2 in the sample stream. Headspace gas is recirculated in a closed loop, passing through a detector unit (LI-840A), where CO2 is measured via infrared spectrometry. Temperature, salinity, and pCO2 were binned in 30-second running medians. This dataset covers all temperature, salinity, and pCO2 data from 2014-2019. Data were quality controlled for anomalous system variables and various system malfunction. Gaps in data coverage represent such failures including but not limited to, detector failure, blocked liquid flow, atmospheric leaks, and power outages. This dataset also includes hourly post-processed (quality assurance / quality controlled) for salinity, temperature, pCO2, and TCO2 measurements taken at Whiskey Creek Shellfish Hatchery, Netarts Bay, Oregon, from 2014 - 2019. Variables such as pH, alkalinity, and saturation state are calculated using a modified version of CarbCalc (similar to CO2Sys). : High-resolution in-situ measurements of salinity, temperature, and pCO2 were collected at a resolution of ~1Hz from 2014 - 2019. pCO2 was measured by equilibrating estuarine water with an enclosed, recirculating headspace that loops through a LiCOR-840, detecting mixing ratio via infrared. To measure hourly TCO2, a seawater sample stream was acidified (0.01ml/min, 30% HCl), and the evolved gas measured via infrared. We paired hourly TCO2 measurements with temperature, salinity, and a time-interpolated value for pCO2. In-filling the carbonate variables at the resolution of the pCO2 measurements is accomplished by implementing a forward-moving, piecewise linear regression (minimum 6 hours with a dynamic salinity range of at least 0.25) for the months of November - March. Slope and intercept output was used to re-calculate alkalinity (Alkalinity = slope*salinity + intercept). From here, variables such as pH, saturation state, and TCO2 were calculated with a custom CarbCalc software (similar to CO2Sys). For the summer months, a simple time-interpolation between hourly alkalinity is calculated onto the pCO2 measurements. For more detail please see the associated thesis.
