PACKAGE DESCRIPTION: This dataset includes chemical, meteorological, physical and surface underway data collected from Investigator in the Indian Ocean, South Pacific Ocean and Tasman Sea from 2015-03-21 to 2015-03-29. 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, SEA SURFACE TEMPERATURE, WIND DIRECTION and WIND SPEED. The instruments used to collect these data include Barometric pressure sensor and Carbon dioxide (CO2) gas analyzer.
These data were collected by Bronte Tilbrook, John Akl and Craig Neill of Commonwealth Scientific and Industrial Research Organization as part of the SOCCOM_096U20150321_UW data set. CDIAC associated the following cruise ID(s) with this data set: 096U20150321
