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.

这是一项继续在北冰洋开发和部署新的冰系剖面浮标的提议，这些浮标是一种自动剖面CTD仪器，能够在大约3年的使用寿命内，在所有季节每天返回海冰下800米海洋上部的高垂直分辨率测量数据。这项建议是在国际范围内进行合作的，计划最终将这项工作的范围扩大到17个投资促进小组。 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化的了解。从拟议的国际试验计划中获得的公开数据将为过程研究和模式验证/同化研究提供基础，这些工作将最终导致更好地了解北冰洋在全球气候变化中的作用。利用这些信息制定一项计划，以便在一系列国际文凭组织的范围内建立和维护独立的试验点，为持续的北冰洋观测系统做出贡献，根据冰系平台北极观测国际讲习班与会者的讨论和建议，
