Sea Surface fCO2 data measured in the English Channel and North Sea onboard R/V Simon Stevin during the coastal cruises in 2017 (NCEI Accession 0170032)
PACKAGE DESCRIPTION: This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Simon Stevin during the coastal cruises in the English Channel and North Sea from 2017-04-03 to 2017-06-21. These data include partial pressure (or fugacity) of carbon dioxide in water, sea surface temperature, sea surface salinity and pressure in the equilibrator. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer, SeaBird temperature and salinity sensor. These data were collected by Thanos Gkritzalis (Flanders Marine Institute, Belgium)

Detailed sampling and analyzing information: | System design: System is using a showerhead packed equilibrator using the design proposed by Frankignoulle (Frankignoulle et al. 2001). Seawater temperature is measured at the intake of the UW system (ship’s bow) using a SBE38 inline temperature sensor. Temperature is also measure before the equilibrator using a SBE21 thermosalinograph and at the equilibrator using a Fluke 45 multimeter and a Pt100 temperature probe. Information of calibration for all sensors is presented below. The system is using a Licor LI7000 NDIR analyser. The sample is partially dried using a Nafion column (Perma Pure MD- 070-48S-4). The seawater flow rate is approx. 2 lpm and and the gas flow rate to the NDIR is approx. 1.8 nlpm. The equilibrator is vented to the atmosphere using a 6m long 1⁄4” OD x 1/8” ID Bev-a-line tubing. |
