By analyzing more than one million surface ocean observations from the Drake Passage, the researchers detected subtle differences between the CO₂ trends in the surface ocean and the atmosphere that suggest a strengthening of the carbon sink that is most pronounced during winter. Although the researchers aren’t sure of the exact mechanism driving these changes, it’s likely related to winter mixing with deep waters that have not had contact with the atmosphere for several hundred years. These results contrast with previous findings that showed that the Southern Ocean’s CO₂ sink had been stagnant or weakening from the early 1990s to the early 2000s. “Given the importance of the southern Ocean to the global oceans’ role in absorbing atmospheric CO₂, these studies suggest that we must continue to expand our measurements in this part of the world despite the challenging environment,” says Colm Sweeney, lead investigator on the Drake Passage study.
Which choice best states the main purpose of the text?
A) To emphasize the difficulty of collecting accurate data from the Southern Ocean
B) To illustrate the problems with amassing an adequate database on the Southern Ocean
C) To place the results of the Drake Passage study in the wider context of other studies
D) To highlight the need to correct the problem of CO₂ absorption before it is too late
