项目摘要

Abstract This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Arctic Observing Network (AON) project will conduct Beaufort Gyre Observational System (BGOS) operations begun in 2003 during 2009-2014 to document the unprecedented changes in sea ice and ocean parameters that are presently occurring in the Beaufort Gyre (BG) region. The project will measure time series of temperature, salinity, currents, geochemical tracers, sea ice draft, and sea level using bottom-tethered moorings and shipboard measurements. Three moorings will acquire precise data on the variations of the vertical distribution of seawater properties, bottom pressures and sea ice draft at sites: 75N and 150W; 78N and 150W; and 77N and 140W. Ship-based sampling covering the entire BG, will be performed 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 delta-18O will be measured and analyzed at 30 standard locations along 140W, 150W, ~ 75N and ~78N sections using shipboard CTD/rosette to provide 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 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.
该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。该北极观测网络(AON)项目将在2009-2014年期间进行博福特环流观测系统(BGOS)的操作,该操作始于2003年,以记录目前在博福特环流(BG)地区发生的海冰和海洋参数的前所未有的变化。该项目将利用系留系泊系统和船上测量,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。三个系泊装置将获取有关现场海水性质垂直分布、底部压力和海冰吃水变化的精确数据:75 N和150 W; 78 N和150 W;以及77 N和140 W。将与加拿大和日本的科学家合作进行覆盖整个BG的船基取样,分担后勤费用,以加强全年的系泊测量。从2003年开始,将使用船上CTD/rosette在沿着140 W、150 W、~ 75 N和~ 78 N剖面的30个标准位置测量和分析温度、盐度、氧、营养盐、钡和δ-18 O,以提供长期时间序列。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,将使用1 100米深度剖面的一次性CTD,以提高温度场和盐度场的空间分辨率。拟议的工作将与大气臭氧的基本要素相协调,以提高观测活动的有效性和相互联系。
