Dissolved inorganic carbon (DIC), total alkalinity (TA), temperature, salinity, oxygen, nutrient, and CTD data collected from discrete profile measurements for Chá Bă mooring time-series validation on cruise TN267 off La Push, Washington (EXPOCODE 325020110729) on R/V Thomas G. Thompson on 2011-08-08 (NCEI Accession 0206905)

This dataset contains data collected from Chá Bă time-series mooring maintenance cruise TN267, representing validation samples for moored time-series observations of ocean acidification water chemistry. This dataset includes temperature and salinity data from CTD sensors and dissolved inorganic carbon concentration, total alkalinity, and nutrient data from Niskin bottle samples collected at the same times and places. Samples were collected on a cruise conducted aboard R/V Thomas G. Thompson to service the Chá Bă ocean acidification mooring off La Push, Washington, on 2011-08-08. This dataset is a subset of a larger dataset of observations collected from Washington coastal waters, in the Strait of Juan de Fuca, and within Puget Sound. The larger dataset spans the time window of February 2008 to October 2018. CTD casts were conducted to measure temperature, conductivity, pressure, and oxygen concentrations using CTD and oxygen sensors. Discrete water samples were collected throughout the water column at all stations in Niskin bottles. Laboratory analyses were run to measure dissolved inorganic carbon (DIC), oxygen, and nutrient concentrations and total alkalinity. More information--including a map of stations occupied during this cruise (and other Salish cruises), full-resolution CTD downcast data for all stations sampled, chlorophyll and phaeopigment concentrations, and other sensor data--can be found at nvs.nanoos.org/CruiseSalish by exploring the Map, Data, and Plots tabs. This effort was conducted in support of the estuarine and coastal monitoring and research objectives of the UW PRISM program and the U.S. National Oceanic and Atmospheric Administration's Ocean Acidification Program and conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network (goa-on.org). The official R/V Thomas G. Thompson code for this cruise is TN267, with support for shiptime provided by the University of Washington (UW) School of Oceanography and the Puget Sound Regional Synthesis Model (PRISM) program at UW.
