ICE2SEA

这项拟议中的研究将填补关于北极海冰、冰川和气候条件在过去12,000年的间冰期中如何变化的知识空白。北冰洋正在经历戏剧性的变化，海冰变薄，并在夏季和冬季进一步向北撤退。这种海冰的退缩极大地影响了北冰洋周围陆地的气候条件。位于这些大陆上的冰盖正逐渐暴露在更温暖的气候条件下，引发表面融化和质量损失的增加，使冰盖也退缩。 我的研究项目ICE 2SEA的长期愿景是调查冰如何影响气候系统在目前的间冰期。我将利用我在冰核科学方面的专门知识，并将其与马尼托巴大学地球观测科学中心的海冰专门知识相结合，通过与加拿大各大学的冰和气候相关研究小组合作，组建一支强大的加拿大研究团队。长期目标是利用过去的知识，更好地预测不断变化的气候和冰冻圈将如何改变北方未来的状况。 在第一个五年期间，我将使用冰芯钻探仪器穿过阿克塞尔海伯格岛的米勒冰帽，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，并培养新一代的HQP。五年研究计划的具体问题是： 1)在过去的几千年里，北冰洋的海冰状况是如何变化的？ 2)在过去的几千年里，北极冰盖经历了什么样的气候条件？ 3)冰川、海冰变化和气候变化之间的关系是什么？ 主要的假设是，在深冰芯中发现的卤溴可以告知过去北冰洋海冰的扩展。 ICE 2SEA的首个五年计划将包括一个PDF，三个博士学位，一个钻井工和几个硕士和本科生级别的项目。这些项目将与其他大学的研究人员共同监督，为HQP环境形成一个强大的国家和国际网络。阿克塞尔海伯格岛是在北方加拿大和我有联系的格里斯峡湾社区（Aujuittuq）是重要的传统和当地知识是可用的。我将聘请个人在这里的实地工作，并将寻找北方申请人的本科生，研究生，博士学位的博士后职位。 加拿大对了解海冰对气候的依赖性非常感兴趣。在8000到5000年前的气候最适期，温度和现在一样温暖，所以此时的海冰范围将告诉我们未来气候变暖的预期。这对北方社区来说是非常重要的知识，对开辟北冰洋航线的愿景具有重要意义。

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.
