2017 seasonal high frequency monitoring of Upper Clark Fork River (Montana, USA) dissolved carbon dioxide, pH, and electrical conductivity

General Information

Data Package:
Local Identifier:	edi.204.9
Title:	2017 seasonal high frequency monitoring of Upper Clark Fork River (Montana, USA) dissolved carbon dioxide, pH, and electrical conductivity
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	These data were collected by the University of Montana and Montana State University to support the Upper Clark Fork River restoration monitoring project supported by the US NSF Long Term Research in Environmental Biology (LTREB) program. The original analytical intent for these data was to assess the response of river metabolic regime to the floodplain restoration via inference of whole-ecosystem metabolism from the daily variation in carbon dioxide concentrations. Data are primarily measurements of dissolved carbon dioxide, pH, electrical conductivity, and temperature in well-mixed river thalweg water. Additional miscellaneous data were collected for quality control. Data are from late in the 2017 field season. Data were collected on the Upper Clark Fork River (USGS HUC 17010201) at the Galen and Racetrack sites northeast of Anaconda, Montana, USA. High frequency carbon dioxide and pH data were collected using field deployments SAMI sensors from Sunburst Sensors (Missoula, Montana, USA). Electrical conductivity data was collected with a HOBO sensor from Onset Computer Corporation (Bourne, Massachusetts, USA).
Purpose:	These data were collected by the University of Montana and Montana State University to support the Upper Clark Fork River restoration monitoring project supported by the US NSF Long Term Research in Environmental Biology (LTREB) program. The original analytical intent for these data was to assess the response of river metabolic regime to the floodplain restoration via inference of whole-ecosystem metabolism from the daily variation in carbon dioxide concentrations.

Methods and protocols used in the collection of this data package

Description:

## 1. Measurement methods Each description below is cross-referenced with the brief methods caption provided in the descriptions of the table columns. ### 1.1 Sensor deployments The following summarizes the methods for deployed sensors. Sensors were cleaned at approximately the same time as quality assurance samples were collected (see below). _Deployed SAMI CO2 probe_: A Submersible Autonomous Moored Instrument (SAMI) CO2 probe (Sunburst Sensors, Missoula, Montana, USA) was deployed directly in the channel thalweg and measured the partial pressure of dissolved CO2 in river water. The pH of the indicator fluid measured by colorimetric absorbance can then be calibrated to the influence of dissolved carbon dioxide gas on the buffering system of the indicator. Calibrations were carried out in the DeGrandpre lab at University of Montana. The probe also records the water temperature and time of measurements. _Deployed SAMI pH probe_: A Submersible Autonomous Moored Instrument (SAMI) pH probe (Sunburst Sensors, Missoula, Montana, USA) was deployed directly in the channel thalweg and measured pH in the river water. Samples of river water are automatically pumped into the SAMI and are passively mixed with indicator dye. A spectrophotometric measurement of the mixture provides a value for pH. The probe also records the water temperature and time of measurements. _Deployed HOBO EC probe_: An Onset Hobo electrical conductivity probe (Onset Computer Corporation, Bourne, Massachusetts, USA) was deployed directly in the channel thalweg and measured the temperature-corrected electrical conductivity in river water. The electrical conductivity is measured by applying a voltage across leads with a specific geometry of connection with river water and measuring the resistance between those leads to conducting an electrical current. The probe also records the water temperature and time of measurements. The software from the manufacturer of the probe (Hobo Onset) provides a post-processor that performs the temperature-correction of the conductivity to 25 degrees Celsius. The factory calibration was used on the instrument. _Deployed HOBO pressure probe_: An Onset Hobo pressure transducer (Onset Computer Corporation, Bourne, Massachusetts, USA) was deployed with the SAMI CO2 probe to track the relative variation in river depth during the deployment. The pressure transducers derives absolute pressure by measuring the deformation of a ceramic diaphragm. The probe also records the water temperature and time of measurements. ### 1.2 Quality assurance sampling The following methods apply to data collected for quality assurance. Sensor deployment data have not been altered based on these measurements, and they are provided for information to users of these data. _Colorimetry with indicator dye_: For quality assurance purposes, pH of discrete river water samples was measured in a laboratory setting following the procedures in Lai et al. (2016). Briefly, indicator dyes were added to river samples stored in a 10-cm cylindrical optical cell. Values of pH for the samples were obtained by monitoring the spectrum of the dye-sample mixture via a Cary 300 spectrophotometer (Varian, Inc.). Measurements are routinely performed at ~20 degrees Celsius and corrected to in situ temperature (i.e. temperature when samples were taken) using the CO2Sys Excel spreadsheet model for the inorganic carbon system (Pierrot et al., 2006). _Gran titration_: Alkalinity samples were measured by acidimetric open-cell titration (Gran 1952). Alkalinity is inferred from non-linear regression analysis from a titration curve between pH values of 3.5 and 3.0. Results of Gran titration are presented as molarity and can be interpreted as the molarity of hydrogen ions neutralized by proton accepting compounds dissolved in the water. _CO2Sys calculated from alkalinity and pH_: The CO2Sys model (Pierrot et al., 2006) was used to calculate the partial pressure of carbon dioxide in sampled river water from the measured alkalinity and pH. Partial pressure of carbon dioxide was calculated for both bottle temperature at time of lab analysis and in situ river water temperature at the time of sample collection. ## 2. Data processing methods This data product is designed to provide the provenance of final tables in a pipeline format, to the degree that provenance is available. Raw data files from instruments and manufacturer software are available in the 01\_input.zip file. The coding used to process the data is available in the 02\_protocol.zip file. In this case, final processing was carried out with R scripts and R markdown files. Incremental files created for the purpose of data processing are available in the 03\_incremental.zip file. Ready-to-use analytical data are available at the data package's root level (on the dataset landing page under the "Resources" section) and are described in the full metadata. ### 2.1.
