PACKAGE DESCRIPTION: This dataset includes Surface underway, chemical, meteorological and physical data collected from CEFAS ENDEAVOUR in the North Sea and South Atlantic Ocean from 2013-07-28 to 2013-07-31. These data include AIR-SEA DIFFERENCE - PARTIAL PRESSURE (OR FUGACITY) OF CARBON DIOXIDE, BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer and Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.
These data were collected by Dr. Naomi Greenwood and Dr. David J. Pearce of The Centre for Environment, Fisheries and Aquaculture Science as part of the Coastal_CEND_14_13 data set. CDIAC associated the following cruise ID(s) with this data set: 74E920130728
