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. To measure key carbon, physical and biogeochemical parameters in coastal waters of the US in relation to Ocean Acidification and monitor changes over time.

CTD/rosette casts were performed with a package consisting of a 24-place, 12-liter rosette frame, a 24-place water sampler/pylon (SBE32) and 24, 11-liter Bullister/Niskin-style bottles. This package was deployed on all stations/casts. Underwater electronic components consisted of a Sea-Bird Electronics (SBE) 9 plus CTD with dual pumps and the following sensors: dual temperature (SBE3plus), dual conductivity (SBE4C), dual dissolved oxygen (SBE43), reference temperature (SBE35), a Wet Labs EDO-AFL/FL fluorometer, a Wet Labs CSTAR transmissometer, a Valeport VA500 altimeter. The CTDs supplied a standard Sea-Bird format data stream at a data rate of 24 frames/second. The SBE9plus CTD was connected to the SBE32 24-place pylon providing for single-conductor sea cable operation. Power to the SBE911plus CTD, SBE32 pylon, auxiliary sensors, and altimeter was provided through the sea cable from the SBE11plus deck unit in the computer lab.

The CTDs supplied a standard Sea-Bird format data stream at a data rate of 24 frames/second. The SBE9plus CTD was connected to the SBE32 24-place pylon providing for single-conductor sea cable operation. Power to the SBE911plus CTD, SBE32 pylon, auxiliary sensors, and altimeter was provided through the sea cable from the SBE11plus deck unit in the computer lab. Shipboard CTD data processing was performed automatically at the end of each deployment using SEABIRD SBE Seasave software version 7.23.2 and AOML Matlab processing software.

Table 3 in the cruise report provides serial numbers for instruments used at each station.; Uncertainty: Two SBE43 dissolved O2 (DO) sensors were used on this cruise. Both sensors tracked each other well. The sensors show a median difference of -0.51 μmol/kg and a standard deviation of 1.04 μmol/kg.; Researcher name: Molly Baringer; Researcher institution: Atlantic Oceanographic and Meteorological Laboratory, National Oceanic and Atmospheric Administration asNeeded Metadata are developed, maintained and distributed by NCEI.
