Observation Status	Temporarily suspended
Description	Underway measurements of CO2 in surface seawater (pCO2_w) and overlying air (pCO2_a) were carried out with the system consisting of a non-dispersive infra-red gas analyzer (NDIR gas analyzer), a shower-head type equilibrator, diaphragm pumps, electric dehumidifiers, Nafion tubing (Perma Pure Inc.), a chemical desiccant column (Mg(ClO4)2), and a data acquisition unit connected to a PC and associated instrumentation.
Meteorological Data Availability (1: Available)	Wind direction: 1 Wind speed: 1 Relative humidity: 1 Precipitation amount: 0 Air pressure: 1 Air temperature: 1 Dew point temperature: 0 Sea water temperature: 0 Sea surface water temperature: 1 Sea water salinity: 0 Sea surface water salinity: 1
Meteorological Data Description	Meteorological data may remain as first provided, even when greenhouse gas data are updated. The file was made using the former WDCGG data file.
