UpTempO: Measuring the Upper Layer Temperature of the Arctic Ocean

该项目将继续在北冰洋开发和部署UpTempO浮标。UpTempO浮标漂浮在海面上，配备(i)海平面压力传感器，（ii）由12个热敏电阻组成的60米长串，以及（iii） 20米和60米深度的两个海洋压力传感器。在项目的下一阶段，研究小组将通过在一些浮标的表面附近增加高精度的电导率/温度对来改进浮标，这将提供校准数据以及在快速变冷的北冰洋中首次提供拉格朗日近表面盐度数据。他们还将进行几项技术改进，包括使用电感调制解调器技术，该技术提供了更灵活的架构。两个短?每年将建造浮标，部署在楚科奇海。每小时记录一次数据，几乎实时地上传到铱星通信网络，然后下载到全球电信系统（GTS）和与国家数据中心相连的调查人员的当地网站。浮标部署使用现有资产，如计划作为其他项目一部分的船舶巡航。该项目解决了几个主要的目标问题，例如，？变暖和海冰覆盖减少对海洋物理系统的影响是什么？然后呢?海冰/海洋系统正在发生变化吗？史无前例地过渡到一个不同的政权？，观察优先级，例如？观察大气和海洋边界层的能量平衡？，以及《？》确定的高度优先区域（例如波弗特海和楚科奇海）。观察海洋和海冰？2005搜索实施研讨会。该团队将计划在西雅图举行的年度极地科学周末（polar Science Weekend）上展示一个关于极地浮标的大型新展览。（ii）与太平洋科学中心合作，作为该项目的一部分，将开发一个新的“当前研究门户”的季节性展览。

This project will continue the development and deployment of UpTempO buoys in the Arctic Ocean. UpTempO buoys float at the ocean surface, equipped with (i) a sea level pressure sensor, (ii) a 60 m long string of 12 thermistors, and (iii) two ocean pressure sensors at 20 m and 60 m depth. In this next phase of the project, the research team will improve the buoy by adding a high precision conductivity/temperature pair near the surface on some buoys, which will provide calibration data as well as the first-ever Lagrangian near-surface salinity data in the rapidly freshening Arctic Ocean. They will also make several technical improvements, including the use of inductive modem technology which provides for a more flexible architecture. Two ?short? buoys will be built per year, for deployment in the Chukchi Sea. Data are recorded hourly, uploaded in near real time to the Iridium satellite communications network and then downloaded to the Global Telecommunications System (GTS) and to the investigators' local web site which is linked to national data centers. Buoy deployment uses existing assets such ship cruises planned as part of other projects. This project addresses several major targeted questions such as, ?What is the impact of warming and reduced sea ice cover on the physical marine system?? And ?Is the sea ice/ocean system undergoing an ?unprecedented transition into a different regime??, observing priorities such as to ?observe the energy balance of the atmospheric and oceanic boundary layers?, and high-priority regions (e.g, the Beaufort and Chukchi Seas) identified in the ?Observing Ocean and Sea Ice? 2005 SEARCH Implementation Workshop. The team will plan a major new exhibit about polar buoys to be shown at (i) the annual Polar Science Weekend at Seattle?s Pacific Science Center and (ii) a new Portal to Current Research season-long exhibit to be developed as part of this project, in collaboration with the PacSciCenter.
