Long-term oceanic observatories (moorings) in the Beaufort Sea during the Canadian Arctic Shelf Exchange Study, 2002-2004

Eight moorings were deployed in the Beaufort Sea during autumn 2002 and were recovered in autumn 2003. In autumn 2003, 16 moorings were deployed and recovered in autumn 2004. Mooring sites included: Mackenzie Shelf (North-Western to North-Eastern), Mackenzie Shelf slope, Kugmallit Valley, Canada Basin, Mackenzie Canyon, Amundsen Gulf (West to East), and Franklin Bay/cape Bathurst area. Bottom depth of deployment sites varied between 63 and 1234 m. Mooring lines were equipped with various oceanographic instruments attached at different depths from 27 m to a maximum of 1234 m. Moored instruments included ALEC conductivity-temperature-turbidity-chlorophyll-PAR sensors, SeaBird SB37 conductivity-temperature sensors, RMC7 and RCM11 current meters, WH-ADCP (300kHz) current profilers, and NIPR and Technicap sediment traps. The datasets available were quality controlled, and have been used in several publications. Variables available include water temperature, conductivity (salinity), density, PAR, Chla, turbidity, oxygen and current velocity (speed and direction). Sediment trap collections were used to estimate downward fluxes of particles, and datasets are described in Metadata CCIN 1076 (Vertical particle flux data in the Beaufort Sea: 2002-2010). Data are also available at the Institute of Ocean Sciences (DFO-Canada).

2002年秋季于波弗特海（Beaufort Sea）部署8套锚系潜标，并于2003年秋季完成回收；2003年秋季再次部署16套锚系潜标，且于2004年秋季回收。本次锚系观测的站点涵盖：麦肯齐陆架（Mackenzie Shelf，西北至东北方向）、麦肯齐陆架坡折带、库格马利特谷（Kugmallit Valley）、加拿大海盆（Canada Basin）、麦肯齐峡谷（Mackenzie Canyon）、阿蒙森湾（Amundsen Gulf，西至东方向）以及富兰克林湾/巴瑟斯特角（Franklin Bay/Cape Bathurst）区域。各部署站点的海底水深介于63米至1234米之间。锚系缆绳在27米至最大1234米的不同深度位置搭载了多类海洋学观测仪器，所使用的仪器包括：ALEC型电导-温度-浊度-叶绿素-光合有效辐射（Photosynthetically Active Radiation, PAR）传感器、SeaBird SB37型电导-温度传感器、RMC7与RMC11型海流计、WH-ADCP（300kHz）剖面海流计，以及日本国立极地研究所（National Institute of Polar Research, NIPR）与Technicap公司生产的沉积物捕集器。本数据集已完成质量控制，且已被多篇学术出版物采用。可获取的观测变量涵盖水温、电导率（盐度）、海水密度、光合有效辐射（PAR）、叶绿素a（Chlorophyll a, Chla）、浊度、溶解氧以及海流流速（含速度与方向）。沉积物捕集器的采集数据用于估算颗粒物质的向下通量，相关数据集的详细信息已在元数据（Metadata）CCIN 1076《波弗特海垂直颗粒通量数据集：2002-2010》中予以说明。数据亦可从加拿大渔业与海洋部海洋科学研究所（Institute of Ocean Sciences, DFO-Canada）获取。
