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 withprevious findings that showed that the Southern Ocean's CO2  sink had been stagnant or weakening from the early 1990s to the early 2000s. "Giventhe importance of the Southern Ocean to the global oceans' role in absorbing atmospheric CO2, these studies suggest that we must continueto expand our measurements in this part of the world despite the challenging environment," says Colm Sweeney, lead investigator on the Drake Passage study .5Which choke best states the main purpose of the text?ATo emphasize the difficulty of collecting accurate data from the Southern OceanBTo illustrate the problems with amassing an adequate database on the Southern OceanCTo place the results of the Drake Passage study in the wider context of other studiesDTo highlight the need to correct the problem of CO2 absorption before it is too late

Recall the pattern of depth integrated anthropogenic carbon accumulation in the ocean.What is the main process that explains the pattern you see and what two factors will explain any feedbacks in a changing climate over the coming decades? [100 words maximum]

An increase in the amount of carbon dioxide in the atmosphere can cause atmospheric temperatures to increase.  Which statement explains how this could affect the ocean as a carbon sink?ResponsesLess atmospheric carbon dioxide would be available to phytoplankton.Less atmospheric carbon dioxide would be available to phytoplankton.Dissolved carbon dioxide gas in the ocean would increase because surface winds would cause a deeper circulation pattern, making more room for the gas. Dissolved carbon dioxide gas in the ocean would increase because surface winds would cause a deeper circulation pattern, making more room for the gas. Less carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean. Less carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean. Less carbon dioxide would be dissolved in the ocean because increasing atmospheric temperatures would cause ocean temperatures to increase.

According to atmospheric temperature and CO2 concentration records derived from Antarctic ice cores, Earth’s climate has undergone significant changes over the past 200,000 years. Click on the image on the right to see two graphs. The upper graph shows the variation in atmospheric CO2 concentration, and the lower graph shows the variation in air temperature. Both graphs cover the same time period from approximately 200,000 years ago up until the year 1950, which is represented as year 0 on the graphs.Describe TWO major causes for the predicted 200 ppm increase in atmospheric CO2 concentration between 1950 and 2050.

The high concentrations of carbon dioxide during the northern hemisphere winter are due to:
