North East Atlantic, primarily around 20° W

Dissolved oxygen parameters in the water column; Wind strength and direction; Partial pressure (pCO2) and fugacity (fCO2) of carbon dioxide in the water column; Salinity of the water column; Temperature of the water column

Anemometers; thermosalinographs; discrete water samplers; gas chromatographs; dissolved gas sensors

Data were collected on UK BOFS cruises during 1989, 1990 and 1991. The system provides surface pCO2, at in-situ temperature. It can also be used in 'discrete' mode to measure pCO2 in water bottle samples at a constant temperature of 12° C. Primary data collection is via the ship's non-toxic sea water supply, obtained from a depth of 2-3m. Sea water is pumped into a 300l volume header tank situated above the main laboratory, then fed by gravity through darkened tubing to the instruments. Other supporting data collected simultaneously include temperature, salinity, dissolved oxygen and wind speed and direction.
