Nansen and Amundsen Basins Observational System (NABOS) 2023 Mooring Design and Cruise Support

南森和阿蒙森盆地观测系统(NABOS)是一项多学科观测计划，包括对海洋、大气和冰的物理和化学观测，并辅之以系泊服务和漂流浮标的部署，以评估海洋在气候变化中的作用。这些观测对北冰洋观测网络至关重要。NABOS项目的目标是了解欧亚盆地东部，包括它的陆架，在重新分配冰和北极东部和西部之间的大部分北极河流水域方面所起的作用。对欧亚盆地东部淡水分配的监测使研究人员能够研究不同大气状况在将淡水分配到盆地不同部分以及进一步向北冰洋中部下游分配方面的作用。目前的项目将支持恢复九个现有的系泊设施，并设计、制造、运输和部署九个新的系泊设施，以支持额外的时间序列观测。伍兹霍尔海洋研究所(WHOI)的系泊作业和工程(MOE)小组将提供专业知识和技术服务，以完成南森和阿蒙森盆地观测系统(NABOS)项目使用的九(9)个深水、冰下、地下系泊设备的设计和制造。这些系泊设施将在2023年夏末的一次巡航期间部署在北冰洋。这项奖励将有助于在出发港口将九个系泊设备动员到指定的船只上。在前往北冰洋东部欧亚盆地的邮轮上，这些系泊设施将可供快速部署。系泊地点提供了一系列东西向的观测，旨在更好地了解淡水在调节横跨该地区和沿该地区的垂直海洋混合方面的作用，以及从海洋内陆向欧亚和马卡洛夫盆地以及拉普特夫北部和东西伯利亚海的海冰地区输送热量的作用。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The Nansen and Amundsen Basins Observational System (NABOS) is a multidisciplinary observational program that includes physical and chemical oceanographic, atmospheric, and ice observations, complemented by servicing of moorings and deployments of drifting buoys to assess the ocean's role in climate change. These observations are critical to the Arctic Ocean observational network. The NABOS project’s goal is to understand the role of the eastern Eurasian Basin, including its shelves, in redistributing ice and the bulk of Arctic riverine waters between the eastern and western Arctic. Monitoring of the partitioning of freshwater in the eastern Eurasian Basin allows researchers to study the role of different atmospheric regimes in distributing freshwater to different parts of the basins and further downstream to the central Arctic Ocean. The current project will support the recovery of nine existing moorings and the design, fabrication, shipping, and deployment of nine new moorings to support an additional period of time-series observations. The Woods Hole Oceanographic Institution’s (WHOI) Mooring Operations and Engineering (MOE) group will provide expertise and technical services to accomplish the design and fabrication of nine (9) deep-water, under-ice, subsurface moorings for use by the Nansen and Amundsen Basins Observation System (NABOS) Project. These moorings will be deployed in the Arctic Ocean during a cruise that will take place in the late summer of 2023. This award will facilitate the mobilization of nine moorings onto the designated vessel at the departure port. The moorings will be available for rapid deployment during a cruise to the Eastern Eurasian Basins of the Arctic Ocean. The mooring locations provide an east-west array of observations designed to better understand the role of fresh waters in regulating vertical ocean mixing across and along this region and the transport of heat from the ocean interior towards areas of sea ice in the Eurasian and Makarov basins and the northern Laptev and East Siberian seas.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
