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浮标漂浮在海洋表面，配备有（i）海平面压力传感器，（ii）60米长的12个电阻串，以及（iii）20米和60米深度的两个海洋压力传感器。在该项目的下一阶段，研究小组将通过在一些浮标的表面附近添加高精度电导率/温度对来改进浮标，这将提供校准数据以及快速清新的北冰洋中首次拉格朗日近表面盐度数据。他们还将进行几项技术改进，包括使用感应调制解调器技术，提供更灵活的架构。两个人？短的？每年将建造浮标，部署在楚科奇海。每小时记录一次数据，以接近真实的时间上传到铱卫星通信网络，然后下载到全球电信系统和与国家数据中心相连的调查人员当地网站。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，如？气候变暖和海冰覆盖减少对海洋系统的影响是什么？然后呢？海冰/海洋系统是否正在经历一个？前所未有的过渡到不同的政权？？，注意优先事项，如？观察大气和海洋边界层的能量平衡，和高度优先区域（例如，博福特和楚科奇海）确定的？观察海洋和海冰？2005年《公约》执行讲习班。 该小组将计划在（i）西雅图的年度极地科学周末？的太平洋科学中心和（ii）一个新的门户网站，目前的研究季节长的展览将开发作为该项目的一部分，与PacSciCenter合作。

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.
