Collaborative Research: Development of an Ice-Tethered Winch for the Seasonal Ice Zone

冰系绞车（ITW）将结合联合收割机的设计两个既定的技术，冰系剖面仪和北极绞车。将这些技术结合起来，将通过创造一种新的仪器来扩展它们各自的能力，这种仪器既可以遥测冰下的地下数据，也可以在不同深度上描绘水柱。ITW将补充其他现有的北极观测工作（例如，通过提供相对高分辨率的全年近地表物理和生物特性（包括温度、盐度、压力、浊度和叶绿素）时间序列（每天四个剖面图，垂直分辨率低于10厘米），利用破冰船勘测、滑翔机和系泊设备进行监测。ITW将在系留于陆固冰的欧拉平台和处于开放水域的半拉格朗日漂流物之间过渡。将根据北极观测网络提供的准则，通过新创建的国际热带气象工作组网站和北极数据和信息合作服务免费实时提供国际热带气象工作组的全年数据。 ITW网站不仅将提供数据门户，还将包括针对公众的项目和地区概述。在部署前，将在阿拉斯加的巴罗举行一次公开演讲。ITW数据将纳入设在百慕大海洋科学研究所的日本财团-POGO观测海洋学英才中心的物理海洋学课程。ITW数据的分析将用于一个学生的研究项目，在CNOE。

The ice-tethered winch (ITW) will combine the design of two established technologies, the Ice-Tethered Profiler and Arctic Winch. Merging these technologies will expand upon their individual capabilities by creating a new instrument that can both telemeter subsurface data from beneath the ice and profile the water column over variable depths. The ITW will complement other existing Arctic observational efforts (e.g., icebreaker surveys, gliders, and moorings) by providing relatively high resolution (four profiles daily with less than 10 cm vertical resolution) time series of year-round, near-surface physical and biological properties, including temperature, salinity, pressure, turbidity, and chlorophyll. The ITW will transition between a Eulerian platform when tethered to landfast ice and a semi-Lagrangian drifter when in open water. Year-round data from the ITW will be freely provided in realtime via a newly created ITW website and the Cooperative Arctic Data and Information Service in accordance with the guidelines provided by the Arctic Observing Network. The ITW website will not only provide a portal for data, but will also include an overview of the project and region targeted to the general public. A public talk will be given in Barrow, Alaska prior to deployment. ITW data will be integrated into the Physical Oceanography curriculum of the Nippon Foundation-POGO Centre of Excellence in Observational Oceanography (CofE) hosted at the Bermuda Institute of Ocean Sciences. Analysis of ITW data will be used in a student research project during CofE.
