A study on the distribution characteristics of dissolved inorganic carbon (DIC) in the Amundsen Sea in 2011.
Listed in NASA Earthdata CMR
To investigate the controls that affect inorganic carbon in the water column of the Amundsen Sea, hydrographic survey using IBRV Araon was carried out from December 20, 2010 to January 22, 2011.
Description
At each site, 377 samples for dissolved inorganic carbon (DIC) were collected from Niskin bottle to 500 ml boro-silicate glass bottles on board. And 374 samples for seawater pH were drawn to 250 ml polypropylene bottle.
In addition to these investigation, to understand the distribution of the various component of carbonic system, underway observation of CO2 parameters was carried out along the cruise track from King George Island to Christchurch. 141 samples were taken from the water inlet that was about 7m below the surface for the IBRV Araon. Accurate measurement concerning spatio-temporal variability in CO2 in the water column is highly important to understanding of global carbon cycle and reliable prediction for the future atmospheric concentration of CO2.

From flux study perspective of CO2, the Amundsen Sea of the Southern Ocean has known as sink for atmospheric CO2 owing to high biological production. But there wasn't enough data, and sea ice have an ambiguous role of air-sea CO2 exchange so that further research must be conducted.
