ICE2SEA

这项拟议的研究将填补关于北极海冰、冰川和气候条件在过去12,000年来的当前间冰期如何变化的知识空白。北冰洋正在经历戏剧性的变化，因为夏季和冬季海冰变薄并进一步向北后退。这次海冰退缩极大地影响了北冰洋周边陆地的气候条件。位于这些陆地上的冰盖正逐渐暴露在气候变暖的条件下，引发表面融化和质量损失的增加，使冰盖也随之后退。我的研究项目冰海的长期愿景是调查冰在目前的间冰期如何影响气候系统。我将利用我在冰核心科学方面的专业知识，并将其与马尼托巴大学地球观测科学中心的海冰专业知识相结合，通过与加拿大大学和与冰和气候有关的研究小组合作，组成一个强大的加拿大研究团队。长期目标是利用过去的知识来改进对气候变化和冰冻圈未来将如何改变朝鲜条件的预测。在第一个五年期间，我将使用穿过阿克塞尔·海贝格岛上的米勒斯冰帽的冰芯钻探仪器来形成一个研究计划。该计划将在加拿大建立新的创新研究领域，并培养新一代HQP。五年研究计划的具体问题是：1)北冰洋海冰条件在过去数千年里是如何变化的？2)北冰洋冰帽在过去数千年里经历了什么气候条件？3)冰川、海冰变化和气候变化之间有什么关系？主要的假设是，在深冰芯中发现的卤素溴可以提供北冰洋海冰过去延伸的信息。在冰海的第一个五年计划将包括一个PDF，三个博士，一个司钻，以及几个硕士和本科水平的项目。这些项目将与其他大学的研究人员共同监督，以形成一个强大的国家和国际HQP环境网络。阿克塞尔·海贝格岛位于加拿大北部，我与格雷斯峡湾社区(Aujuittuq)有联系，都有重要的传统和当地知识可用。我将在这里聘请个人进行实地工作，并为本科生、研究生、博士和博士后职位寻找北方申请者。对加拿大来说，了解海冰对气候的依赖是非常重要的。8000到5000年前的气候最佳期的温度和现在一样温暖，所以这个时候的海冰面积将会告诉我们未来气候变暖的情况。这对北方社区来说是非常重要的知识，对在北冰洋开通航道的愿景也很重要。

The proposed research will fill a knowledge gap on how the Arctic sea ice, glaciers, and climate conditions have changed through the present Interglacial period, the last 12,000 years. The Arctic Ocean is undergoing dramatic changes as sea ice thins and retreats further north during both summer and winter seasons. This sea ice retreat greatly affects the climatic conditions of the landmasses surrounding the Arctic Ocean. Ice caps situated on these landmasses are gradually being exposed to warmer climatic conditions, triggering an increase in surface melting and a loss of mass, making the ice caps retreat as well. The long-term vision of my research program ICE2SEA is to investigate how ice has influenced the climate system during the present interglacial period. I will use my expertise in ice core science and combine it with the sea ice expertise found in the Centre for Earth Observation Science at the University of Manitoba to form a strong Canadian research team through collaboration with Canadian universities with ice- and climate-related research groups. The long-term goal is to use the knowledge from the past to improve predictions on how the changing climate and cryosphere will change conditions in the North in the future. For the first five-year period, I will use the instrument of ice-core drilling through the Müllers Ice Cap on Axel Heiberg Island to form a research program. The program will build new and innovative research fields in Canada and train a new generation of HQP. The specific questions for the five-year research program are: 1) How did sea ice conditions change in the Arctic Ocean during past millennia ? 2) What climatic conditions did the Arctic ice caps experience during past millennia ? 3) What is the relationship between glaciers, sea ice change, and climate change ? The main hypothesis is that the halogen Bromine found in a deep ice core can inform on the past extension of sea ice in the Arctic Ocean. The inaugural five-year program in ICE2SEA will include one PDF, three PhDs, one driller, and several Master's- and undergraduate-level projects. The projects will be co-supervised with researchers from other universities to form a strong national and international network for the HQP environment. Axel Heiberg Island is in Northern Canada and I have contact with the Grise Fjord community (Aujuittuq) were important traditional and local knowledge is available. I will hire personal here for the field work and will look for Northern applicants for the undergraduate, graduate, PhD's an PostDoc positions. Knowledge of the dependence of sea ice on climate is of strong interest for Canada. Temperatures were as warm as present 8000 to 5000 years ago in the Climatic Optimum so the sea ice extent at this time will inform us on what to expect in the future warming climate. This is very important knowledge for the Northern communities, and has importance for the visions of opening of shipping routes in the Arctic Ocean.
