This Arctic Observing Network (AON) project will continue Beaufort Gyre Observing System (BGOS) operations begun in 2003 during 2013-2018 to document the unprecedented changes in sea ice and ocean parameters that are presently occurring in the Beaufort Gyre (BG) region. The BG is a unique circulation component within the Arctic Ocean physical environmental system reflecting a set of specific atmospheric, sea-ice, and oceanic conditions that have significant interrelationships with the Arctic-wide as well as global climate systems. We will continue measuring time series of temperature, salinity, currents, geochemical tracers, sea ice draft, and sea level using bottom-anchored moorings and shipboard measurements. BGOS moorings plus two Japanese moorings (at no cost to this project) will acquire precise data on the variations of the vertical distribution of seawater properties, bottom pressures, sea ice draft and surface waves (during open water conditions) at scientifically important sites within the BG system. Ship-based synoptic sampling covering the Beaufort Gyre will continue to be performed each summer in collaboration with scientists in Canada and Japan, with shared logistics expenses, to augment the year-round mooring measurements. Temperature, salinity, oxygen, nutrients, barium, and 18O will continue to be measured and analyzed at standard locations along sections at 140W, 150W, ~ 75N and ~78N using a shipboard CTD/rosette to continue the long-term time series started in 2003. Samples that provide information on longer time-scales, such as CFCs and carbon tetrachloride, alkalinity, total CO2, dissolved inorganic carbon and tritium/3He, will be collected less frequently. Between CTD/rosette casts, expendable CTDs that profile to 1100 m depth will continue to be used to increase spatial resolution of the temperature and salinity fields. The proposed work will be coordinated with the basic elements of AON to enhance effectiveness and interconnections of observational activities, and the field program will continue to accommodate other AON and NSF funded projects when able. Data will be made available on the project website with a metadata pointer in ACADIS.

该北极观测网络（AON）项目将在2013-2018年期间继续开展2003年开始的博福特环流观测系统（BGOS）业务，以记录博福特环流（BG）区域目前发生的海冰和海洋参数的前所未有的变化。BG是北冰洋物理环境系统中一个独特的环流组成部分，反映了一套特定的大气、海冰和海洋条件，这些条件与整个北极以及全球气候系统有着重要的相互关系。我们将继续使用底锚系泊和船上测量来测量温度、盐度、海流、地球化学示踪剂、海冰吃水和海平面的时间序列。BGOS系泊系统加上两个日本系泊系统（本项目不承担任何费用）将在BG系统内具有重要科学意义的地点获得关于海水特性、海底压力、海冰吃水和表面波（在开放水域条件下）垂直分布变化的精确数据。每年夏天将继续与加拿大和日本的科学家合作，在博福特环流范围内进行船基天气取样，分摊后勤费用，以加强全年的系泊测量。温度、盐度、氧气、营养物、钡和18 O将继续在标准位置沿着140 W、150 W、~ 75 N和~ 78 N的剖面上使用船上CTD/玫瑰花形图进行测量和分析，以继续2003年开始的长期时间序列。提供较长时间尺度信息的样品，如氟氯化碳和四氯化碳、碱度、二氧化碳总量、溶解无机碳和氚/3 He，将不经常收集。在CTD/玫瑰花形模型之间，将继续使用剖面达1 100米深度的一次性CTD，以提高温度场和盐度场的空间分辨率。拟议的工作将与AON的基本要素进行协调，以增强观测活动的有效性和相互联系，并且现场计划将继续在可能的情况下容纳其他AON和NSF资助的项目。 数据将在项目网站上提供，并在ACADIS中提供元数据指针。
