项目摘要

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.

这个北极观察网络（AON）项目将继续Beaufort Gyre观察系统（BGOS）运营始于2003年在2013 - 2018年期间，以记录目前在Beaufort Gyre Gyre（BG）地区发生的海冰和海洋参数的前所未有的变化。 BG是北极海洋物理环境系统中的独特循环成分，反映了一组特定的大气，海冰和海洋状况，与北极范围内以及全球气候系统具有显着相互关系。我们将使用底部锚定的系泊设备和船上的测量值继续测量温度，盐度，电流，地球化学示踪剂，海冰草稿和海平面的时间序列。 BGOS系泊以及两个日本系泊设备（无需支付该项目）将获取有关BG系统中科学重要地点的海水特性，底部压力，海冰草稿和表面波（在开放水域条件下）垂直分布的垂直分布变化的精确数据。涵盖Beaufort Gyre的基于船舶的概要抽样将与加拿大和日本的科学家合作，并以共同的物流费用进行，以增强全年的系泊测量。使用船上CTD/rosette沿着140W，150W，〜75n和〜78N的沿沿沿沿沿标准的标准位置进行温度，盐度，氧气，养分，钡和18O将继续测量和分析。无机碳和tritium/3HE的收集频率较低。在CTD/玫瑰花塞铸件之间，将继续使用该剖面为1100 m的消耗性CTD继续用于增加温度和盐度场的空间分辨率。拟议的工作将与AON的基本要素协调，以增强观察活动的有效性和互连，并且现场计划将继续在能够的情况下适应其他AON和NSF资助的项目。数据将在项目网站上使用Acadis的元数据指针提供。
