项目摘要
In pursuit of its goal "to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean, and to establish the sensitivity of these distributions to changing environmental conditions", in 2015 the International GEOTRACES Program will embark on several years of research in the Arctic Ocean. In a region where climate warming and general environmental change are occurring at amazing speed, research such as this is important for understanding the current state of Arctic Ocean geochemistry and for developing predictive capability as the regional ecosystem continues to warm and influence global oceanic and climatic conditions. The three investigators funded on this award, will manage a large team of U.S.scientists who will compete through the regular NSF proposal process to contribute their own unique expertise in marine trace metal, isotopic, and carbon cycle geochemistry to the U.S. effort. The three managers will be responsible for arranging and overseeing at-sea technical services such as hydrographic measurements, nutrient analyses, and around-the-clock management of on-deck sampling activites upon which all participants depend, and for organizing all pre- and post-cruise technical support and scientific meetings. The management team will also lead educational outreach activities for the general public in Nome and Barrow, Alaska, to explain the significance of the study to these communities and to learn from residents' insights on observed changes in the marine system. The project itself will provide for the support and training of a number of pre-doctoral students and post-doctoral researchers. Inasmuch as the Arctic Ocean is an epicenter of global climate change, findings of this study are expected to advance present capability to forecast changes in regional and globlal ecosystem and climate system functioning.As the United States' contribution to the International GEOTRACES Arctic Ocean initiative, this project will be part of an ongoing multi-national effort to further scientific knowledge about trace elements and isotopes in the world ocean. This U.S. expedition will focus on the western Arctic Ocean in the boreal summer of 2015. The scientific team will consist of the management team funded through this award plus a team of scientists from U.S. academic institutions who will have successfully competed for and received NSF funds for specific science projects in time to participate in the final stages of cruise planning. The cruise track segments will include the Bering Strait, Chukchi shelf, and the deep Canada Basin. Several stations will be designated as so-called super stations for intense study of atmospheric aerosols, sea ice, and sediment chemistry as well as water-column processes. In total, the set of coordinated international expeditions will involve the deployment of ice-capable research ships from 6 nations (US, Canada, Germany, Sweden, UK, and Russia) across different parts of the Arctic Ocean, and application of state-of-the-art methods to unravel the complex dynamics of trace metals and isotopes that are important as oceanographic and biogeochemical tracers in the sea.
为了实现其目标“确定过程并量化控制海洋中关键痕量元素和同位素分布的通量,并确定这些分布对不断变化的环境条件的敏感性”,2015年,国际地理领域计划将在北极海洋中进行数年的研究。在一个以惊人的速度发生气候变暖和一般环境变化的地区,随着区域生态系统的流动,研究对了解当前的现状和发展预测能力至关重要 由该奖项资助的三名调查人员将管理一大批的美国成员团队,他们将通过常规的NSF提案过程进行竞争,以贡献自己在海洋微量金属,同位素和碳循环地球化学方面的独特专业知识。 这三位经理将负责安排和监督AT-SEA技术服务,例如水文测量,营养分析以及所有参与者依靠的甲板采样活动的固定管理,并组织所有前和后灌木前和后的技术前和后技术支持和科学会议。 管理团队还将为阿拉斯加诺姆和巴罗的公众领导教育外展活动,以解释研究对这些社区的重要性,并从居民对海洋系统中观察到的变化的见解中学习。 该项目本身将提供许多博士前学生和博士后研究人员的支持和培训。由于北极海洋是全球气候变化的震中,因此这项研究的发现有望提高目前的能力,以预测区域和上一流的生态系统和气候系统运作的变化。由于美国对北极海洋倡议的贡献,这项项目将成为一项努力的一部分,以进一步的海洋知识。 这项美国探险队将在2015年北极夏季重点关注西方北极海洋。科学团队将由通过该奖项资助的管理团队以及来自美国学术机构的科学家团队组成,他们将成功竞争并获得NSF资金,并在及时获得特定科学项目的NSF资金,以便在巡航计划的最终阶段参加。 巡航轨道细分市场将包括白令海峡,丘奇架和深加拿大盆地。 几个电台将被指定为所谓的超级站,用于对大气气溶胶,海冰和沉积物化学以及水柱工艺进行严格研究。 In total, the set of coordinated international expeditions will involve the deployment of ice-capable research ships from 6 nations (US, Canada, Germany, Sweden, UK, and Russia) across different parts of the Arctic Ocean, and application of state-of-the-art methods to unravel the complex dynamics of trace metals and isotopes that are important as oceanographic and biogeochemical tracers in the sea.
