Halocarbons in surface water from SWEDARP97/98
A number of parameters of biogeochemical interest were monitored along a north–southerly transect (S 43-S 63°) in the Atlantic Sector of the Southern Ocean from the 8th to the 20th of December 1997. Changes in total dissolved inorganic carbon (CT) and total alkalinity (AT) were mostly dependent on t...
