This archival package contains dissolved inorganic carbon, pH, oxygen, and other variables collected from surface discrete and surface underway observations during the East Coast Ocean Acidification (ECOA) Cruise. The East Coast Ocean Acidification (ECOA) Cruise on board the R/V Gordan 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.

  • Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: DIC; Unit: umol kg-1; Observation type: Surface discrete measurement; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Sampling instrument: Pump seawater from underway system ; Analyzing instrument: Two Picarro Cavity Ring-Down Spectroscopy instruments; Detailed sampling and analyzing information: The method is based on dual isotope dilution and cavity ring-down spectroscopy (DID-CRDS). In this method, seawater is continuously sampled and mixed with a flow of NaH13CO3 solution that is also enriched in deuterated water (the spike). The isotopic composition of CO2 (delta 13C spiked_sample) derived from the DIC in the mixture, and the D/H ratio of the mixed water (delta D spiked_sample), are measured by CRDS analyzers. The D/H of the water in the mixture allows accurate estimates of the mixing ratio of the sample and the spike. [DIC] of the sample is then calculated from the mixing ratio, [DI13C] of the spike, and delta 13C spiked_sample. ; Uncertainty: less than 0.03%; Quality flag convention: 2: good data 3.Questionable data; Method reference: An Ultrahigh Precision, High-Frequency Dissolved Inorganic Carbon Analyzer Based on Dual Isotope Dilution and Cavity Ring-Down Spectroscopy Kuan Huang, Nicolas Cassar, Bror Jonsson, Wei-jun Cai, and Michael L.

  • Parameter or Variable: pH; Abbreviation: PH_RAW, PH_TOT; pH scale: NBS, Total; Observation type: Surface underway; In-situ / Manipulation / Response variable: in-situ; Measured or calculated: measured; Analyzing instrument: Honeywell Durafet III Non-Glass pH electrode with Vario Pin Connector; Temperature of pH measurement: In engine room, ~2 m after the seachest, before the seawater pumps, SBE-38; Detailed sampling and analyzing information: Raw output of pH (in NBS scale) was presented without a calibration. Spectrophotometric pH analyses on discrete samples were used for the calibration of raw data. Corrected pH = Measured pH + delta pH, where delta pH = Spec pH (total, at Durafet temperature) - Durafet pH (NBS scale, at water temperature in the flow through cell) = -0.005268 X Temperature + 0.01551. Slope and intercept came from the linear regression of delta pH and the water temperature in the flow through cell. Then the pH at sea surface temperature condition was calculated via CO2SYS using SST and SSS from SBE 38 and SBE 45 and the total alkalinity estimated from the linear relationship with SSS (TA_EST = 49.027 X SSS + 598.73, R2 = 0.98, this relationship was developed from the discrete surface bottle samples collected from the ECOA cruise).; Researcher name: Yuan-Yuan Xu; Researcher institution: University of Delaware.

Equilibrated gasses diffused into a fused-silica capillary (2 m in length and 0.05 mm in diameter) that connects to a quadruple mass spectrometer (Pfeiffer vacuum) for ion current intensity and ratio measurements. Calibration was conducted automatically every 3 hours for 20-min using ambient air, which has a stable O2/Ar. The analysis procedure for O2Ar: 1. Remove abnormal data due to instrument stop, unacceptable pressure, and unstable flow rate; 2. Remove 8-min data (e-folding time) after switching between air and water inlets; 3. In every 2-min, O2 Ar ratio were measured about 120 times. Only data within 95% confidence interval were averaged; 4. delta_O2Ar = [(O2/Ar)warter - (O2/Ar)air]/(O2/Ar)air; Uncertainty: precision of EIMS: plus/minus 0.2%; Quality flag convention: 2: good data 3.Questionable data; Method reference: Cassar, N., B.
