To address the "Arctic gap" in the ocean observing system, the National Science Foundation funded an instrument-development project in July 2003 entitled: "An Ice-tethered Instrument for Sustained Observation of the Arctic Ocean." This new instrument concept is for an expendable, ice-tethered variation of the now-operational Moored Profiler (MP) instrument developed at the Woods Hole Oceanographic Institution (WHOI) with NSF support. A loose array of these Ice-Tethered Profilers (ITP's) is envisioned, repeatedly sampling the upper ocean below the perennial ice pack and telemetering the data back in real time to the users ashore. Long lifetime and modest cost will permit coarse, basin-scale coverage to be maintained through regular seeding of replacement systems as necessary, similar to the surface ice buoys of the International Arctic Buoy Program (IABP). Operationally, the ITP array will serve as the Arctic analogue of the ARGO float program now being initiated in the lower-latitude oceans. Ideally, an array of such ice-tethered platforms can serve as an effective observing system of the polar surface atmosphere and sea ice conditions as well as the upper-Arctic Ocean. Moreover, addition to the ice platforms of a telecommunications link through the surface ice pack would allow the array to serve as the backbone for two-way transmissions to buoys, AUVs, and subsurface moorings in the Arctic Ocean as well as acoustic tomographic receivers. In order to optimize the capabilities of future Arctic observing systems and to coordinate international efforts in Arctic observing, this group will hold a workshop entitled "Arctic Observing Based on Ice- Tethered Platforms" at WHOI, June 23-25, 2004. This workshop will be a logical continuation of an earlier Arctic Instrumentation Workshop. It is expected that approximately 40 key experts plus interested scientists and students from the USA, Canada, Germany, Great Britain, Norway, Russia, and possibly other countries will attend to brainstorm ideas of ice-tethered observing systems. Support is included here to cover the travel and lodging expenses of meeting participants, the meeting logistics, and report preparation and dissemination. Intellectual Merits: The proposed workshop will contribute significantly to the design and implementation of a full Arctic atmosphere, sea ice, and ocean observing system. It is expected that this workshop will push the boundaries in environmental measurements and telemetry capabilities, as well as the collection, acquisition, integration, analysis, synthesis, access, and long-term preservation of the observations. Broader Impacts: This workshop will bring together experts from different countries to coordinate the efforts of various countries in Arctic studies. Results of the workshop will be widely distributed through the internet and scientific publications. Additionally, the workshop will have educational impact through the involvement of graduate students.

为了解决海洋观测系统中的“北极差距”，美国国家科学基金会于2003年7月资助了一个仪器开发项目，题为：“用于持续观测北冰洋的冰系仪器”。“这个新的仪器概念是一个消耗性的，冰系的变化，现在的业务停泊剖面仪（MP）仪器开发的伍兹霍尔海洋研究所（WHOI）与NSF的支持。这些冰系剖面仪（ITP）的松散阵列的设想，反复采样常年冰层下的上层海洋和遥测数据在真实的时间回到岸上的用户。寿命长，成本低，将允许通过必要时定期投放替代系统来维持粗略的流域规模覆盖，类似于国际北极浮标计划（IABP）的表面冰浮标。在操作上，ITP阵列将作为目前正在低纬度海洋启动的实时地转海洋学阵列浮标方案的北极模拟。理想的情况是，一系列这样的冰系平台可以作为极地表面大气和海冰状况以及北冰洋上部的有效观测系统。此外，除了冰平台外，通过表面冰层建立电信联系将使该阵列成为向北冰洋浮标、自动潜航器和地下系泊装置以及声波层析成像接收器进行双向传输的骨干。 为了优化未来北极观测系统的能力并协调北极观测方面的国际努力，该小组将于2004年6月23日至25日在世界卫生组织举办一次题为“基于冰系平台的北极观测”的讲习班。该讲习班将是早先的北极仪器仪表讲习班的合理延续。预计将有来自美国、加拿大、德国、英国、挪威、俄罗斯和可能的其他国家的大约40名主要专家和感兴趣的科学家和学生参加，集思广益，探讨冰系观测系统的设想。支助包括与会者的旅费和住宿费、会议后勤以及报告的编写和分发。 智力优势：拟议的讲习班将大大有助于设计和实施一个完整的北极大气、海冰和海洋观测系统。预计该讲习班将推动环境测量和遥测能力以及观测数据的收集、获取、综合、分析、合成、获取和长期保存方面的界限。 更广泛的影响：这次研讨会将汇集来自不同国家的专家，协调各国在北极研究方面的努力。讲习班的成果将通过互联网和科学出版物广泛传播。此外，讲习班将通过研究生的参与产生教育影响。
