Four bay-wide cruises were conducted in the Chesapeake Bay on R/V Rachel Carson on May 4–6, June 6–10, August 8–12, and October 10–13, 2016, and one bay-wide cruise was on a commercial boat on February 21–22, 2019. The surface underway data from these cruises are archived at NCEI as Accession 0191507. The field research was supported by the U.S. National Oceanic and Atmospheric Administration, NOAA (NA15NOS4780190).

This dataset includes chemical data from discrete samples and accompanying physical data from a profiling CTD collected during the M/V Norseman II and M/V Tiglax Seward Line cruises N2S10 and TXF10 (EXPOCODEs: 32QO20100503 and 33A020100914) in the Gulf of Alaska, North Pacific Ocean from 2010-05-03 to 2010-09-18. These data include dissolved inorganic carbon (DIC), total alkalinity (TA), temperature, salinity, oxygen, nutrients (Nitrate, Nitrite, Phosphate, and Silicate) and other parameters. The cruise was funded by the North Pacific Research Board (NPRB), the National Oceanic and Atmospheric Administration (NOAA), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council (EVOSTC). The carbon data were collected and analyzed by personnel at the Ocean Acidification Research Center (OARC) at the University of Alaska Fairbanks (UAF). The CTD operations on the cruise were managed by personnel from the College of Fisheries and Ocean Sciences (CFOS) at UAF. The nutrient data were analyzed by the Whitledge Laboratory at CFOS-UAF. Data files are in .csv format and titled with the ship code (e.g., TX), the season (S = Spring and F = Fall), and the year (e.g., 08-17).

This dataset consists of data collected during the CCGS John P. Tully cruise 2019.23 (EXPOCODE 18DD20190829) in the Salish Sea and off the west coast of Vancouver Island of the North American Pacific coast from 2019-08-29 to 2019-09-06 as part of the La Perouse Water Properties Survey. Discrete dissolved inorganic carbon (DIC), total alkalinity (TA), salinity, and nutrient samples were taken from rosette casts with 10L Niskin bottles and analysed at the Institute of Ocean Sciences. Discrete samples of dissolved oxygen were also collected and analysed onboard the vessel. CTD profiles were recorded with each rosette cast. DIC and TA samples were placed in cold storage for 1-4 weeks before analysis. A total of 61 DIC and TA pairs were sampled with a 22 percent replication rate. Replicates are not averaged in this dataset and appear individually, indicated by decimal sample ID's (e.g. 26.1, 26.2). The pooled standard deviations (of difference between replicate pairs) were calculated to be 6 umol/kg and 5 umol/kg respectively. Replicates with a QC flag = 3 were included in the pooled standard deviation calculation but replicate pairs with at least one QC flag = 4 (n = 1) were excluded.

The World Ocean Circulation Experiment (WOCE) was a major component of the World Climate Research Program with the overall goal of better understanding the ocean's role in climate and climatic changes resulting from both natural and anthropogenic causes. The CO2 survey took advantage of the sampling opportunities provided by the WOCE Hydrographic Program (WHP) cruises during this period between 1990 and 1998. The final collection covers approximately 23,000 stations from 94 WOCE cruises.

Near-shore estuarine and coastal regions are where most recreational fishing and tourism occur, yet they are vastly under-sampled. Their susceptibility to OA is not well understood due to their high biogeochemical variability. These regions are affected by land-side processes such as river discharge and run-offs and ocean-side processes through slope water exchange. A full determination of the carbonate system in these regions in conjunction with open ocean measurements is needed to increase our understanding of the effects of OA on ocean health and fisheries and our ability to predict them. In this project, we propose to augment several observational campaigns by 1) adding a carbonate component to the harmful algal blooms (HABs) monitoring cruises conducted periodically on the Western Florida Shelf in order to study potential links between HABs and OA, 2) renewing our collaboration with select National Parks to complement and enhance our near-shore data collection on the Northern Gulf of America and US East Coast, and 3) complementing our underway surface pCO2 measurements in the Gulf of America and US East Coast with underway total alkalinity measurements to help us improve our fundamental understanding of nearshore OA processes. The addition of these measurements to the current assets already present in the region would enhance our understanding of the linkage between nearshore and open ocean processes and better assess the mechanisms and impacts of OA on the biogeochemistry, biology and their economic consequences.
