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.

These datasets consist of profile data collected by CTD casts in the northern Gulf of Mexico that are collected as part of the annual summer groundfish survey supported by the Southeast Area Monitoring and Assessment Program (SEAMAP). SEAMAP is a State/Federal/university program for collection, management and dissemination of fishery-independent data and information in the southeastern United States. Data are in Sea-Bird CNV format.

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.

This dataset contains Water temperature, salinity, and oxygen data from CTD and water sampling taken from NOAA Ship Ronald H. Brown, cruise RB-22-04, in the Northwestern Tropical Atlantic. Cruise RB-22-04 by research vessel Ronald H. Brown in 2022 had the objective to service a number of moored platforms for the NTAS and MOVE projects (Northwest Tropical Atlantic Station and Meridional Overturning Variability Experiment, resp.). 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. Data are in NetCDF. The raw CTD data are available as separate files.

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.

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.

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.

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.

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.
