Tillamook Estuary, OR Ocean Acidification Monitoring Dataset: 2017-2020
On this page:
This dataset is composed of coastal acidification monitoring observations from the Tillamook Estuary, OR, USA conducted by EPA’s Pacific Coastal Ecology Branch (PCEB). The measurements span from September 2017 to June 2020, and consist of quality-controlled data from YSI sondes, Sea-Bird SeaFET and SeapHOx, and Sunburst SAMI CO2 sensors. Sensor measurements consisted of salinity, temperature, water depth, dissolved oxygen, pH, and partial pressure of CO2 (pCO2) in seawater. Coastal acidification monitoring in Tillamook Estuary is planned to continue, and this dataset represents the first batch of quality-controlled data resulting from the monitoring effort. Results from this effort will be used as part of PCEB's research efforts to improve coastal acidification monitoring and attribution of acidification drivers in Pacific Northwest estuaries. This dataset will be shared with EPA Office of Water for an assessment of coastal acidification monitoring in EPA National Estuary Program sites around the United States, and submitted to the Oregon Department of Environmental Quality for their 2022 Integrated Report and relevant water quality assessments.
