Collaborative Reaseach: BEST - A service proposal to examine impacts of sea-ice on the distribution of chlorophyll-a over the eastern Bering Sea shelf

为收集、质量控制、分析和分发给所有BEST调查人员的叶绿素-a核心数据的服务项目提供资金。这个项目将支持一个人在每个夏季巡航。数据将在PMEL、NODC和阿拉斯加海洋观测系统（AOOS）的数据库中免费提供。除了本提案的服务部分，pi将利用该提案的生物数据，结合a)春季和夏季BEST巡航收集的物理和化学数据b) 9月NPCREP巡航收集的数据c)系泊和卫星跟踪的漂浮物收集的数据来解决一个假设：较远洋的南部大陆架和较底栖的北部大陆架之间的显著差异是海冰边缘在从冬季强风到夏季温和条件过渡期间的位置造成的。

Funds are provided for a service project to collect, quality control, analyze and distribute to all BEST investigators the core chlorophyll-a data. This project will support one person on each summer cruise. Data will be freely available on databases at PMEL, NODC, and the Alaska Ocean Observation System (AOOS). In addition to the service portion of this proposal, the PIs will use the biological data from this proposal combined with a) physical and chemical data collected on spring and summer BEST cruises b) data from a September NPCREP cruise c) data from moorings and from satellite-tracked drifters to address one hypothesis:The marked difference between the more pelagic southern shelf and the morebenthic northern shelf is a result of the position of the sea-ice edge during thetransition from strong winter winds to milder summer conditions.
