CTD (Conductivity Temperature Depth) data were collected offshore of California and Oregon from October to November 2018 during NOAA cruise SH-18-12 on the R/V Bell M. Shimada (USGS field activity 2018-663-FA). This data release supersedes version 2.0, published in September 2021 at https://doi.org/10.5066/P99DIQZ5.

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 2018 during NOAA cruise SH-18-12 on the R/V Bell M. Shimada (USGS field activity 2018-663-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 2.0, published in September 2021 at https://doi.org/10.5066/P99DIQZ5. Versioning details are documented in the accompanying VersionHistory_P99MJ096.txt file.

CTD (Conductivity Temperature Depth) data were collected along the Cascadia margin for the FK190612 expedition in June 2019

CTD (Conductivity Temperature Depth) data were collected October-November 2019 offshore of California and Oregon as part of the ongoing EXPRESS: Expanding Pacific Research and Exploration of Submerged Systems project. The data were collected using an SBE 49 FastCAT V 1.2a CTD profiler attached to the “Yogi” ROV launched from the National Oceanic and Atmospheric Administration’s (NOAA’s) R/V Reuben Lasker (NOAA cruise R-19-05).

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.

Following in a long tradition of hydrographic studies of the California Current system, the data in this report were collected during the 27-30 March 2012 cruise of the Pacific Coast Ocean Observing System (PaCOOS) program aboard the R/V Point Sur. The PaCOOS program was organized in 2003/2004 as the NOAA west coast contribution to the national Integrated Ocean Observing System (IOOS), and is charged with "providing ocean information for the sustained use of the California Current Large Marine Ecosystem under a changing climate. PaCOOS cruises generally subsample the standard California Cooperative Oceanic Fisheries Investigations (CalCOFI) grid of hydrographic stations. This PaCOOS cruise did exactly that, sampling along CalCOFI line 67 from Moss Landing, California, to station 90 (CTD casts 1-19). To increase the resolution of the hydrographic data and to maintain the convention of similar recent PaCOOS cruises, eight CTD casts were also inserted between the standard CalCOFI sites along line 67. Participants on the cruise came from the Naval Postgraduate School (Physical Oceanography, Nutrient Analysis), the Monterey Bay Aquarium Research Institute (Nutrient Analysis, Primary Productivity), University of California at Santa Cruz (Zooplankton Analysis), and Moss Landing Marine Laboratories (Nutrient Analysis).
