Dissolved inorganic carbon (DIC), total alkalinity (TA), temperature, salinity, oxygen, nutrient, and CTD data collected from discrete profile measurements during Puget Sound cruise RC001 (EXPOCODE 33IY20180407) on R/V Rachel Carson from 2018-04-07 to 2018-04-11 (NCEI Accession 0206802)

This dataset contains data collected from the Puget Sound cruise that took place from 2018-04-07 to 2018-04-11 aboard as the inaugural cruise of the University of Washington's R/V Rachel Carson. Twenty seven time-series stations were occupied in the Salish Sea and adjoining coastal waters in Washington State marine waters. The cruise was designed to obtain a synoptic snapshot of key carbon, physical, and other biogeochemical parameters as they relate to ocean acidification (OA) in Washington's estuarine and coastal environments. At all sampling stations, 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 Washington Ocean Acidification Center (WOAC) and conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network (goa-on.org) and the U.S. National Oceanic and Atmospheric Administration's Ocean Acidification Program. The official R/V Rachel Carson code for this cruise is RC001, with shiptime supported by WOAC.
