This dataset contains CTD profiles of temperature, salinity, and oxygen from the 2022 Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) Northeast Extension cruise RB-22-04 on board of the NOAA ship Ronald H. Brown. Data are in NetCDF.

This dataset contains CTD profile data of dissolved oxygen, CDOM, chlorophyll a, temperature and salinity data that were collected during the East Coast Ocean Acidification (ECOA) Cruise on board NOAA Ship Gordon Gunter from Newport, took place in the Gulf of Maine and then along the East US coast to Miami. The effort was in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP). The cruise was designed to obtain a snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. The cruise included a series of 11 transects approximately orthogonal to the Gulf of Maine and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.

This dataset contains water temperature, salinity, and oxygen profiles taken by CTD and water sampling. Cruise RB-20-06 by NOAA Ship Ronald H. Brown in 2020 had the objective to service moored platforms for the NTAS and MOVE projects (Northwest Tropical Atlantic Station and Meridional Overturning Variability Experiment). To calibrate and validate the mooring data, CTD casts with salinity water samples were collected; these data are reported here. The CTD sensor data have been quality-controlled and adjusted using the water sample data. The raw CTD data are available as separate files. Data are in NetCDF.

This dataset includes chemical, discrete sample, physical and profile data collected from NOAA Ship OCEANOGRAPHER in the Coral Sea, North Pacific Ocean, Solomon Sea and South Pacific Ocean from 1987-06-06 to 1987-07-05. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, Potential temperature (theta), SALINITY, WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include CTD and bottle. These data were collected by Stanley P. Hayes of NOAA Pacific Marine Environmental Laboratory (PMEL) as part of the GLODAPv2_31OC19870606 dataset. CDIAC associated the following cruise ID(s) with this dataset: TEW_WST2 The GLobal Ocean Data Analysis Project (GLODAP) is a cooperative effort to coordinate global synthesis projects. The central objective of this project is to generate a unified dataset, a uniformly calibrated open ocean data product on inorganic carbon and carbon-relevant variables, to help determine the global distributions of both natural and anthropogenic inorganic carbon, including radiocarbon. These estimates provide an important benchmark against which future observational studies will be compared. They also provide tools for the direct evaluation of numerical ocean carbon models.

The second Gulf of Mexico and East Coast Carbon (GOMECC-2) Cruise on board NOAA Ship Ronald H. Brown from Miami, took place in the Gulf of Mexico and then along the East US coast to Boston. The effort was in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP). The cruise was designed to obtain a snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. This was the second occupation, with the first occurring in 2007, and complemented mooring time series and other regional OA activities. The cruise included a series of 8 transects approximately orthogonal to the Gulf of Mexico and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.

This dataset contains water temperature, salinity, and oxygen data taken by CTD and water sampling from NOAA Ship Ronald H. Brown in the North Atlantic Ocean. Cruise RB-20-07 in 2020 had the objective to service a number of moored platforms for the MOVE project (Meridional Overturning Variability Experiment). To calibrate and validate the mooring data, CTD casts with salinity and oxygen water samples were collected; these data are reported here. The CTD sensor data have been quality-controlled and adjusted using the water sample data. The raw CTD data are available as separate files. Data are in NetCDF.

Oceanographic temperature, salinity, oxygen, transmissivity, and PAR measurements collected using CTD from NOAA Ship McArthur II during 2007 as part of PACOOS.

The fourth Gulf of Mexico Ecosystems and Carbon Cycle (GOMECC-4) Cruise took place on board the NOAA Ship Ronald H. Brown, from September 13–October 21, 2021. The cruise departed from Key West, FL into the Gulf of Mexico and then around the coastal waters of the Gulf of Mexico in a counter-clockwise direction, ending in St. Petersburg, FL. The effort was in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP). The cruise was designed to obtain a snapshot of key carbon, physical, biogeochemical and biological parameters as they relate to ocean acidification (OA) in the coastal realm. This was the fourth occupation of the Gulf of Mexico as part of OAP’s monitoring efforts in the region, with the previous ones occurring in 2007, 2012, and 2017. The cruise included a series of 15 transects approximately orthogonal to coast of the Gulf of Mexico and a 16th partial transect along the 27°N line, between Florida and the Bahamas, as well as a comprehensive set of underway measurements. This dataset includes the processed, 1db-binned CTD profile data collected in the 141 stations.

This dataset consists of CTD profile measurements of water temperature, salinity, dissolved oxygen concentration, stimulated fluorescence of chlorophyll A, CDOM colored dissolved organic matter and other hydrographic and chemical parameters obtained during the East Coast Ocean Acidification (ECOA-3) Cruise on board the NOAA Ship Ronald H. Brown in the East Coast US, North Atlantic Ocean from 2022-08-06 to 2022-09-23. The effort was in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP). The cruise was designed to obtain a snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. The cruise included a series of 24 transects approximately orthogonal to the Gulf of Maine and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.

This product was developed as part of the project supported by the grant from and the National Oceanic and Atmospheric Administration’s Ocean Acidification Program under award NA18OAR0170430 to the Virginia Institute of Marine Science. The data product consists of water quality data for tidal 98 stations for 1984–2018. The source data used to generate this product were downloaded from the Chesapeake Bay Program’s (CBP) data hub. Out of the total of 255 monitoring stations in the Tidal Monitoring Program, we selected 98 with the long monitoring record (30 years or longer). The following variables were downloaded from the data hub at the native temporal and vertical resolution (between one and four cruises per month and approximately 10 depth levels sampled between 0 and 37 m) for 1984–2018: water temperature (T), salinity (S), pH, total alkalinity (TA), dissolved oxygen (DO) , and chlorophyll (Chl). All pH data prior to 1998 were removed because of the data quality concerns (Herrmann et al., 2020). Briefly, we found a dramatic difference in long-term trends between stations measured by institutions in the state of Virginia and stations measured by the state of Maryland, particularly from late spring to early fall. The boundary between the station groups runs east–west within the mesohaline portion of the bay, where the Potomac River estuary intersects the mainstem bay. The boundary separates strong negative linear trends to the south (Virginia stations) from neutral and weakly positive linear trends to the north (Maryland stations). For all variables, data entries marked with CBP’s “Problem” and “Qualifier” flags were removed. Additionally, all variables were scanned for extreme outliers: for each variable, data from all stations, depths, and times were combined into a single composite sample for which the 75th and 25th percentiles (i.e., the upper and lower quantiles) and the interquartile range (the difference between the upper and lower quantiles) were calculated. Extreme outliers were defined as the values falling outside of a certain number (censoring criterion) of interquartile ranges from the upper and lower quantiles.
