PACKAGE DESCRIPTION: This dataset includes Surface underway, chemical, meteorological and physical data collected from R/V Investigator in the Indian Ocean, South Pacific Ocean, Southern Oceans from 2017-01-14 to 2017-09-17. These data include 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.
