项目摘要
The West Antarctic Ice Sheet presently holds enough ice to raise global sea level by up to five meters if it all melted. Information from satellites demonstrates that the West Antarctic Ice Sheet is losing ice faster than any other region in the Antarctic. However, how much of the West Antarctic Ice Sheet will melt and how quickly it will happen when average global temperature exceeds 2 degrees celsius is currently unknown. At the current rate of CO2 emissions to the atmosphere, average global temperatures will be 1.5 degrees celsius and 2.0 degrees celsius above preindustrial levels in 10 and 20 years, respectively. Sea level rise is one of the clearest planet-wide signals of this human-induced climate change. Global mean sea level has increased by ~22 cm since 1880 and will continue to rise well beyond the 21st century. Given the far-reaching and international consequences of Antarctica’s future contribution to global sea level rise, the SWAIS 2C Project was developed through an international collaboration of scientists from nine countries in order to better forecast the size and timing of future changes. The international SWAIS 2C Project scientists will collect and study geological (rocks, sediments), glaciological (ice), and geophysical (Earth physical properties) data and provide new information to guide the development of climate and ice sheet numerical models to better understand and predict how the ice sheet on West Antarctica will contribute to future sea level rise. The project aims to interpret the state of past environmental conditions in West Antarctica (warm open marine seas, cold ice-covered ocean, or grounded ice sheet) during recent periods in Earth’s history when the average global temperature reached or exceeded 2 degrees celsius, a level anticipated within the next two decades. These types of geological studies will help us understand how much and how fast the ice melted during past warm periods and what processes are involved. Modeling studies will use this new information regarding past and present ice sheet behavior to make better predictions of how much and how fast the West Antarctic Ice Sheet will melt in the future. This proposal will support German members of the SWAIS 2C project to study the chemical and physical properties of sediments deposited at different times in the past in order to determine what the climate was like and what environmental conditions prevailed at the drilling site during the past and if a trans-Antarctic seaway opened.
南极洲西部冰盖目前拥有足够的冰,如果全部融化,将使全球海平面上升5米。来自卫星的信息表明,南极洲西部冰盖的冰损失速度比南极洲任何其他地区都快。然而,当全球平均气温超过2摄氏度时,南极西部冰盖会融化多少,以及融化的速度有多快,目前尚不清楚。按照目前二氧化碳向大气排放的速度,10年和20年后,全球平均气温将分别比工业化前水平高出1.5摄氏度和2.0摄氏度。海平面上升是人类引起的气候变化的最明显的全球信号之一。自1880年以来,全球平均海平面上升了约22厘米,并将在21世纪世纪以后继续上升。鉴于南极洲未来对全球海平面上升的影响深远,SWAIS 2C项目是通过来自9个国家的科学家的国际合作开发的,以便更好地预测未来变化的规模和时间。国际SWAIS 2C项目科学家将收集和研究地质(岩石,沉积物),冰川(冰)和地球物理(地球物理特性)数据,并提供新的信息来指导气候和冰盖数值模型的开发,以更好地了解和预测南极洲西部冰盖将如何有助于未来海平面上升。该项目的目的是解释南极洲西部过去的环境条件(温暖的开阔海洋,寒冷的冰层覆盖的海洋或地面冰盖)在地球历史上的最近时期,当全球平均气温达到或超过2摄氏度时,预计在未来二十年内达到这一水平。这些类型的地质研究将帮助我们了解在过去的温暖时期,冰融化的数量和速度以及所涉及的过程。建模研究将利用这些关于过去和现在冰盖行为的新信息,更好地预测未来南极西部冰盖融化的程度和速度。该提案将支持SWAIS 2C项目的德国成员研究过去不同时期沉积的沉积物的化学和物理性质,以确定过去钻探地点的气候和环境条件,以及是否有跨南极海道开放。
