An Ice-Tethered Profiling Instrument for Sustained Observation of the Arctic Ocean

P.I.Toole(WHOI)提案#：0324233提案标题：用于持续观测北冰洋项目摘要的冰绳剖面仪PI提议设计、建造和测试一台自动化的、易于部署的冰绳剖面仪(ITP)，该剖面仪能够返回三年生命周期内所有季节北冰洋上层海洋温度和盐度的每日高垂直分辨率测量结果。浮标将近乎实时地传输数据，而且成本低，允许系统被视为消耗性系统，避免了昂贵的回收操作的需要。ITP将被设计为支持第三方插件模块，如地面气象传感器和声学系统。这一发展将建立在支持多个离散地下仪器的冰绳漂浮器以及世界卫生组织开发的系泊剖面仪的过去成功的基础上。PIS设想在整个北冰洋建立一个由大约20个ITP组成的松散阵列，用于观测上层海洋的年度和年际变化。两个系统将在2004年年中建造并部署在计划中的巡航上。根据这些单元的性能，仪器设计将在必要时进行修改，并将建造另外两个系统，以便在2005年的一次机遇巡航中部署。在此期间，和平研究所将与极地研究界协商，制定一项建立和维护一系列国际空间站的计划，这将有助于建立一个可持续的北冰洋观测系统。

P.I. Toole (WHOI) Proposal #: 0324233Proposal Title: An Ice-Tethered Profiling Instrument for Sustained Observation of the Arctic Ocean Project SummaryThe PIs propose to design, build, and test an automated, easily deployed Ice-Tethered Profiler (ITP) capable of returning daily high-vertical-resolution measurements of upper ocean temperature and salinity in the Arctic Ocean during all seasons over a three-year lifetime. The buoy will transmit data in near-real time and be low-cost, allowing systems to be considered expendable, avoiding the need for expensive recovery operations. The ITP will be designed to support third-party plug-in modules such as surface meteorological sensors and acoustic systems. This development will build on the past success of ice-tethered drifters supporting multiple discrete subsurface instruments as well as the WHOI-developed Moored Profiler. The PIs envision a loose array of approximately 20 ITPs throughout the Arctic Ocean for observation of annual and interannual variations of the upper ocean. Two systems will be fabricated and deployed on a planned cruise in mid-2004. Based on the performance of these units, the instrument design will be modified if necessary and two more systems will be constructed for deployment on a cruise of opportunity in 2005. During this time, in consultation with the polar research community, the PIs will develop a plan for establishing and maintaining an array of ITPs that will contribute to a sustained Arctic Ocean observing system.
