项目摘要
The East Antarctic ice sheet became fully established in the middle Miocene, about 14 million years ago. It is not known why the ice sheet grew at this time, although it is believed that the ice sheet expansion happened in 'fits and starts', over 2 to 3 million years. This time interval is known as the middle Miocene climate transition. Geochemical records show that levels of atmospheric carbon dioxide were not noticeably lower after the climate transition than before. However, this does not necessarily imply that this important greenhouse gas did not influence the climate at this crucial time in Earth's history. Indeed, large changes in the isotopic composition of carbon in the ocean suggest that there were large changes in the global carbon cycle associated with the intervals of rapid ice sheet growth within the climate transition. This proposal aims to determine whether levels of atmospheric carbon dioxide changed within the climate transition, in association with the bursts of ice sheet growth and decay. We will construct records of carbon dioxide trends (i.e., increasing/decreasing carbon dioxide) and sea surface temperatures. We will also generate detailed stratigraphies from different sites, which will enable us to link these records with other records of ice volume, deep sea temperatures and weathering. This will provide the first truly integrated record of the middle Miocene climate transition. This will provide valuable information on the causes and effects of the establishment of the Antarctic ice sheet. The records should shed light on the erratic nature of the climate transition. The long term climate transition appears to have punctuated by intervals of climatic amelioration and deglaciation. The processes operating during such intervals have direct relevance to our understanding of the modern day Antarctic ice sheet and its behaviour under future global warming scenarios.
东南极冰盖在大约1400万年前的中新世中期完全形成。目前尚不清楚冰盖为什么在这个时候增长,尽管人们相信冰盖的扩张是在200万到300万年间断断续续地发生的。这一时间间隔被称为中中新世气候过渡。地球化学记录显示,气候过渡后,大气中的二氧化碳水平并没有明显低于气候过渡前。然而,这并不一定意味着这种重要的温室气体在地球历史上的这个关键时刻没有影响气候。事实上,海洋中碳的同位素组成的巨大变化表明,在气候过渡期间,全球碳循环发生了与冰盖快速增长的间隔期相关的重大变化。这项提议旨在确定大气二氧化碳水平是否在气候过渡期间发生了变化,与冰盖的生长和衰退有关。我们将建立二氧化碳趋势(即二氧化碳增加/减少)和海面温度的记录。我们还将生成不同地点的详细地层,这将使我们能够将这些记录与其他关于冰量、深海温度和风化的记录联系起来。这将提供中新世中期气候转变的第一个真正完整的记录。这将为南极冰盖形成的前因后果提供有价值的信息。这些记录应该会揭示气候过渡的反复无常的性质。长期的气候过渡似乎被气候改善和冰川消融的间歇所打断。在这种时间间隔内运行的过程与我们对现代南极冰盖及其在未来全球变暖情景下的行为的理解有直接关系。
