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. To measure key carbon, physical and biogeochemical parameters in coastal waters of the Gulf of Maine and eastern coast of the US in relation to Ocean Acidification.

CTD/rosette casts were performed with a package consisting of a 24-place, 10-liter rosette frame (AOML's yellow frame), a 24-place water sampler/pylon (SBE32) and 24, 10-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 (SBE3), dual conductivity (SBE4), dual dissolved oxygen (SBE43), and a Simrad 807 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 SBE9plus CTD, SBE32 pylon, auxiliary sensors, and altimeter was provided through the sea cable from the SBE11plus deck unit in the computer lab.

Post cruise data processing was completed on a Windows 7 machine running SEABIRD SBE DATA Processing version 7.22.5; Uncertainty: Conductivity sensor calibration coefficients derived from the pre-cruise calibrations were applied to raw primary and secondary conductivities. Comparisons between the primary and secondary sensors and between each of the sensors to check sample conductivities. Post cruise calibration of the primary sensor determined the sensor drift to be 0.0008 PSU/month.; Method reference: http://www.aoml.noaa.gov/ocd/gcc/ECOA1/Cruise_Report.pdf.; Researcher name: Joe Salisbury; Researcher institution: Ocean Processes Analysis Laboratory, University of New Hampshire Parameter or Variable: CTD oxygen; Abbreviation: oxygen; Unit: % Sat, umol/kg, mg/l; Observation type: profile; In-situ / Manipulation / Response variable: in-situ observation; Measured or calculated: measured; Calculation method and parameters: SBE 43; Sampling instrument: Sea-Bird SBE-911plus CTD system; Detailed sampling and analyzing information: A detailed and more complete description is available in the cruise report at: http://www.aoml.noaa.gov/ocd/gcc/ECOA1/Cruise_Report.pdf.
