Surface water underway pCO2 autumn data in the Eastern Weddel Gyre, coast of Dronning Maud Land, Kong Håkon VII Hav, Antarctica, and the Southern Ocean Atlantic sector, to Cape Town, in Feb-April 2019

Sea surface fugacity/partial pressure of carbon dioxide (fCO2ssw/pCO2ssw) was measured in autumn, 26 February-10 April 2019, from Punta Arenas, Chile, across the Weddell gyre and the eastern sector in the Atlantic sector of the Southern Ocean, coast off the Dronning Maud Land, Kong Håkon VII Hav, An...

Description
Summary:Sea surface fugacity/partial pressure of carbon dioxide (fCO2ssw/pCO2ssw) was measured in autumn, 26 February-10 April 2019, from Punta Arenas, Chile, across the Weddell gyre and the eastern sector in the Atlantic sector of the Southern Ocean, coast off the Dronning Maud Land, Kong Håkon VII Hav, Antarctica, to Cape Town, South Africa. The study transect was passing through the ice-covered Astrid Ridge region near the Antarctic coast at 68˚S and in the Maud Rise region south of 66˚S in the Weddell Sea. CO2 data coverage during autumn is sparse and this dataset contributes with new surface water xCO2, pCO2 and fCO2 data with focus on the coast off the Dronning Maud Land, Antarctica, to Cape Town, South Africa ( lat 69.007S to 33.9865S long -52.7716E to 18.2651E) . This dataset highlights the importance of increasing seasonal CO2 observations especially during autumn/winter to improving the coverage of surface CO2 data and flux estimates in the seasonal sea ice-covered regions of the Southern Ocean.
