Design and Initialization of an Ice-Tethered Profiler Array Contributing to the Arctic Observing System

这是一项关于在北冰洋继续开发和部署新的冰系绳剖面浮标的建议，该浮标是一种自动剖面CTD仪器，能够在大约3年的生命周期内返回所有季节海冰下800米上层海洋的每日高垂直分辨率测量结果。该提案是国际范围内的合作项目，计划最终将这项工作的范围扩大到最多17个项目工作队。理想情况下，它们将与一套其他自动化仪器一起部署。这种来自所有季节和多年的高垂直分辨率CTD数据的新来源将以前所未有的数量增加对北冰洋状态和变异性的了解。拟议的国际海洋观测计划的公开数据将为过程研究和模式验证/同化研究提供基础，这两项工作最终将有助于更好地了解北冰洋在全球气候变化中的作用。此外，该项目将与极地研究界协商，根据国际讲习班与会者的讨论和建议，制定一项计划，以便在国际海洋观测组织对北冰洋可持续观测系统作出贡献的范围内建立和维持国际海洋观测计划。

This is a proposal to continue development and deployment in the Arctic Ocean of new ice-tethered profiling (ITP) buoys that are an automated profiling CTD instrument capable of returning daily high-vertical-resolution measurements of the upper 800 m ocean underneath sea-ice during all seasons over an approximately 3-year life time. The proposal is collaborative on an international scale and the plan is to eventually extend the scope of this work to involve up to 17 IPTs. Ideally they would be deployed in conjunction with a suite of other automated instruments.This new source of high-vertical-resolution CTD data from all seasons and from multiple years will increase knowledge of the state and variability of the Arctic Ocean by an unprecedented amount. The publicly available data from the proposed ITPs will provide the basis for both process studies and model validation/assimilation research, work that will ultimately lead to better understanding of the Arctic Ocean's role in global climate change.In addition, the project will, in consultation with the polar research community, use this information to develop a plan for establishing and maintaining ITPs within a full array of IBO's contributing to a sustained Arctic Ocean observing system, as was discussed and recommended by participants of the international workshop Arctic Observing Based on Ice-Tethered Platforms.
