There is compelling evidence that the Earth has been warming dramatically since the end of the 19th century as a consequence of increasing atmospheric CO2. This study aims to understand the long-term role of the Southern Ocean as a 'store-house' for CO2, and its significance in controlling changes in the Earth's climate. We will use coral skeletons from the deep oceans as archives of ocean circulation and nutrient levels. This information will help unravel how biological activity in the Southern Ocean has responded during previous episodes of climate change, and how this has controlled the levels of CO2 in the Earth's atmosphere. This will provide a better understanding of greenhouse warming and its effect on our future climate.

有令人信服的证据表明，自 19 世纪末以来，由于大气中二氧化碳含量的增加，地球急剧变暖。 这项研究旨在了解南大洋作为二氧化碳“储存库”的长期作用及其在控制地球气候变化方面的重要性。 我们将利用深海的珊瑚骨骼作为海洋环流和营养水平的档案。 这些信息将有助于揭示南大洋的生物活动在之前的气候变化过程中是如何反应的，以及它是如何控制地球大气中二氧化碳水平的。这将使人们更好地了解温室变暖及其对未来气候的影响。
