项目摘要

The rise in atmospheric CO2, caused largely by the burning of fossil fuel, is the most important factor driving the recent change in our planet's climate. Direct measurements of atmospheric CO2 only started in the 1950s - so how do we know that the rise in atmospheric CO2 is unprecedented? To look into the past we use a unique geologic archive: the bubbles of air trapped in ice cores from the polar ice sheets. Ice cores from specially selected sites, can yield, detailed yearly records for recent centuries, or records spanning the last 800 thousand years (the time that anatomically modern humans first appeared). Uniquely among natural archives of change, ice cores contain samples of the three major greenhouses gases (carbon dioxide, methane and nitrous oxide) captured a little after the snow fell, and an isotopic record of atmosphere temperature. Ice cores thus provide the most compelling evidence that the changing concentration of greenhouse gases is driving natural climate change, which has taken the planet through many cycles of glaciation and warmth. In coming years, ice cores will answer key questions. 1) What is the lag between rising greenhouse gas (GHG) concentrations and global temperature? 2) Why did the Earth enter a regular cycle of glacial to interglacial transitions 500 thousand years ago that dominated planetary change until the industrial era? 3) How did the higher than pre-industrial concentrations of GHG affect our planet in the last interglacial period 120 thousand years ago? Existing and planned ice cores, collected from Antarctica, Greenland and high-mountain glaciers, are a unique window into the past changes in the atmosphere. Providing crucial data to drive and test computer models exploring how and why climate changed in the past. This in turn informs projections of how the climate will change in the future. We propose to develop a facility, UK-RArE-GAS, at the British Antarctic Survey (BAS), to help scientists from around the UK, and their collaborators, to extract and analyse ancient air samples from ice. The custom system will incorporate an extraction method, facilities to ensure proper stewardship of these precious ancient air samples, and analysis with a novel laser spectrometer. No such facility is currently available in the UK, and this limits our scientists to collaborating and paying for analyses in one or two laboratories in the EU or US. UK-RArE-GAS will be augmented into the existing ice core laboratory at BAS, the centre of ice core science in the UK and a leader in the international community. The existing ice core lab hosts a large laboratory freezer, state-of-the-art ice chemistry instrumentation (ICP-mass spectrometry and Fast-ion chromatography), and a continuous flow analysis system to measure a suite of chemistry and stable water isotopes in ice. BAS also provides a suite of rapid-access, shallow, intermediate and deep ice-core drills that are widely used by the UK community and our collaborators. The innovative 'gas-line' will considerably enhance the existing capabilities, providing an unparalleled capability to UK science. Dr Thomas Bauska, who joined BAS as a Royal Society Fellow has direct experience in development of similar ice-core gas methods, and will oversee design and development of the facility.The UK-RArE-GAS laboratory will create a centre for collaboration among UK and International partners who can use the laboratory to extract gases in glacial ice samples.
大气中二氧化碳的增加,主要是由化石燃料的燃烧引起的,是推动我们这个星球最近气候变化的最重要因素。对大气二氧化碳的直接测量在20世纪50年代才开始--那么我们怎么知道大气二氧化碳的上升是前所未有的呢?为了回顾过去,我们使用了一种独特的地质档案:极地冰盖冰芯中的气泡。来自特别选择的地点的冰芯,可以产生近几个世纪的详细年度记录,或者跨越过去80万年(解剖学上的现代人第一次出现的时间)的记录。在自然变化档案中,冰芯独一无二地包含了降雪后捕获的三种主要温室气体(二氧化碳、甲烷和一氧化二氮)的样本,以及大气温度的同位素记录。因此,冰芯提供了最令人信服的证据,表明温室气体浓度的变化正在推动自然气候变化,而自然气候变化已经使地球经历了多次冰川和变暖周期。在接下来的几年里,冰芯将回答关键问题。1)温室气体(GHG)浓度上升和全球温度之间的滞后时间是什么?2)为什么地球在50万年前进入了一个从冰川到间冰期的规则周期,直到工业时代为止,这种周期一直主导着地球的变化?3)在12万年前的最后一个间冰期,高于工业化前的温室气体浓度是如何影响我们的地球的?从南极洲、格陵兰岛和高山冰川收集的现有和计划中的冰芯是了解过去大气变化的独特窗口。为驾驶和测试探索过去气候变化方式和原因的计算机模型提供关键数据。这反过来又为未来气候如何变化的预测提供了信息。我们计划在英国南极调查局(BAS)开发一个名为英国稀有气体的设施,以帮助来自英国各地的科学家和他们的合作者从冰中提取和分析古代空气样本。定制系统将包括一种提取方法,确保这些珍贵的古代空气样本得到适当管理的设施,以及使用新型激光光谱仪进行分析。英国目前还没有这样的设施,这限制了我们的科学家只能在欧盟或美国的一个或两个实验室合作并支付分析费用。英国-稀有天然气将被扩大到BAS现有的冰芯实验室,BAS是英国的冰芯科学中心,也是国际社会的领先者。现有的冰芯实验室拥有一台大型实验室冷冻机、最先进的冰化学仪器(电感耦合等离子体质谱仪和快速离子色谱仪),以及一套连续流动分析系统,用于测量冰中的一套化学和稳定的水同位素。BAS还提供了一套快速、浅、中、深冰芯钻机,被英国社区和我们的合作者广泛使用。创新的“天然气管道”将极大地增强现有的能力,为英国科学提供无与伦比的能力。托马斯·鲍斯卡博士作为皇家学会会员加入BAS,他在开发类似的冰芯气体方法方面拥有直接经验,并将监督该设施的设计和开发。英国-稀有气体实验室将在英国和国际合作伙伴之间建立一个合作中心,这些合作伙伴可以使用该实验室从冰川冰样中提取气体。
