Various water column variables, including salinity, dissolved inorganic nutrients, pH, total alkalinity, dissolved inorganic carbon, radio-carbon isotopes were measured in samples collected using a Niskin-bottle rosette at selected depths from sites offshore of California and Oregon from October to November 2019 during NOAA Ship Lasker R-19-05 (USGS field activity 2019-672-FA). CTD (Conductivity Temperature Depth) data were also collected at each depth that a Niskin-bottle sample was collected and are presented along with the water sample data. This data release supersedes version 1.0, published in August 2020 at https://doi.org/10.5066/P9ZS1JX8. Versioning details are documented in the accompanying VersionHistory_P9JKYWQU.txt file.

This dataset contains the CTD measurements collected by Dr. Gregory C. Johnson of the Pacific Marine Environmental Laboratory during the West Coast Ocean Acidification cruises in 2013. Leg 1 was surveyed onboard NOAA Ship Fairweather from August 5 to 10, 2013. The original cruise names for Leg 1 are: WCOA-13, CC1-13-FA. Leg 2 was surveyed onboard R/V Point Sur from August 21 to 28, 2013. The original cruise names for Leg 2 are: WCOA-13, CC2-13-PS.

Cruise RL-24-04 by NOAA Ship Reuben Lasker in March/April 2024 had the objective to service moorings for the CCE (California Current Ecosystem) project, as well as the CORC (Consortium on the Ocean's Role in Climate) project. To calibrate and validate the mooring data, CTD casts with water samples were taken. The CTD data are reported here. The CTD data have been quality-controlled and adjusted using the water sample data. The raw instrument data (*.xmlcon and *.hex files from the software by Sea-Bird Scientific) are provided as well. Additional cruise data files are available through the NOAA Rolling Deck to Repository program (R2R, also at NCEI, see 'references'), and the water sample data will be published separately through the Ocean Carbon and Acidification Data Portal at NCEI. Processed data are in NetCDF.

This dataset contains water temperature, salinity, and other parameters collected by CTD from NOAA Ship Ronald H. Brown in the north Pacific Ocean off California. Cruise RB-21-02 in June 2021 had the objective to service moorings for the CCE (California Current Ecosystem) project, as well as the CORC (Consortium on the Ocean's Role in Climate) project. To calibrate and validate the mooring data, CTD casts with water samples were done. The CTD data are reported here. The CTD data have been quality-controlled and adjusted using the water sample data. Additional cruise data files are available through the NOAA Rolling Deck to Repository program (R2R, see references under 'Documentation' bullet on this dataset landing page), and the water sample data are published separately through the Ocean Carbon and Acidification Data Portal at NCEI (also in references). The raw instrument data (*.xmlcon and *.hex files from the software by Sea-Bird Scientific) are also available. Processed data are in NetCDF and also in CNV format.

The Southeast Area Monitoring and Assessment Program (SEAMAP) is a State/Federal/university program for collection, management and dissemination of fishery-independent data and information in the southeastern United States. This dataset consists of profile data collected by CTD casts during cruises in 2021.
