United States Participation in the Activities of the International Arctic Science Committee

一名在国际北极科学委员会（IASC）中代表美国北极科学界利益的美国北极研究高级科学家，并担任IASC理事会主席，将加强美国对国际北极科学的参与和领导。 北极在科学上非常重要，在全球包括气候变化中发挥着重要作用。 然而，在北极进行研究会带来许多实际问题，例如，这是一个恶劣和偏远的环境;在该地区的大部分地区没有永久性设施;八个不同的国家控制着北冰洋的各个部分和邻近的陆地地区。 因此，北极地区的国际合作不仅有益，而且往往至关重要。 机构间常设委员会成立于1990年，旨在鼓励和促进这种合作，为科学家之间以及科学家与政府之间就各种北极科学主题交流信息提供了一个论坛。 机构间常委会还通过支持小型的重点科学规划会议/讲习班，支持各国北极研究工作的国际协调。 美国参加并领导机构间常委会及其理事会，将协助机构间常委会优先处理以下问题：评估气候和气候变化对北极及其人民的影响;绘制北冰洋国际测深图;研究人类在驯鹿/驯鹿放牧系统中的作用;研究北极冻原生态系统的生物复杂性和生物多样性;并向北极理事会提供科学咨询意见，北极理事会是一个政府间组织，其重点是北极环境与土著人民之间的互动。

United States participation in and leadership of international Arctic science will be strengthened by a senior U.S. Arctic research scientist representing the interests of the U.S. Arctic science community in the International Arctic Science Committee (IASC) and by serving as President of the IASC Council. The Arctic is very important scientifically and plays a strong role in global, including climate, change. However the conduct of research in the Arctic poses many pragmatic problems, e.g., it is a harsh and remote environment; no permanent facilities can be located in much of the region; and eight different countries control various parts of the Arctic Ocean and adjacent land areas. Thus, international cooperation in the Arctic is not only useful, but often essential. IASC, established in 1990 to encourage and promote such cooperation, provides a forum for exchange of information among scientists and between scientists and governments on a wide variety of Arctic science topics. IASC also supports international coordination of national Arctic research efforts by supporting small focused scientific planning meetings/workshops. U.S. participation and leadership in IASC and its Council will assist IASC to address on a priority basis: an assessment of the impact of the climate and climatic changes on the Arctic and its peoples; development of an international bathymetric chart of the Arctic Ocean; a study of the role of humans in caribou/reindeer grazing systems; a study of biocomplexity and biodiversity in Arctic tundra ecosystems; and providing scientific advice to the Arctic Council, an intergovernmental organization that focuses on interaction between the Arctic environment and its indigenous peoples.
