Ocean-Ice Interaction Measurements using Autonomous Ocean Flux Buoys in the Arctic Observing System

这是一项建议，继续在北极中部部署，并将自主海洋通量浮标（AOFB）的部署扩展到北极西部，在浮冰上部署协同位置的仪器，测量T/S剖面、冰通量和表面强迫，包括大气体积通量和辐射项。对海洋内部和海洋表面之间的热、盐和动量的垂直通量的观测对于我们理解和模拟维持北极常年冰覆盖的过程非常重要，特别是在冰覆盖和体积变化如此迅速的时候。北极系统正在发生的变化，特别是其热力学平衡的变化，可能是未来更广泛变化的前兆。然而，缺乏充分记录这些过程的观察结果。为了开始解决这一测量差距，建议在四年的时间里每年部署4个海洋通量浮标。该奖项为第一年的扩展部署提供资金，同时网络设计在SEARCH和国际极地年（2007-2008）的支持下进行。这项工作将与其他研究人员一起进行，他们将提供免费的、在同一地点进行的观察，并分担后勤费用，否则后勤费用将是压倒性的。基于冰系平台的北极观测国际研讨会的与会者讨论并推荐了这种合作方式。

This is a proposal to continue deployment in the Central Arctic and to extend deployment to the Western Arctic of Autonomous Ocean Flux Buoys (AOFB) on ice floes with co-located instruments measuring T/S profiles, ice fluxes and surface forcing including atmospheric bulk fluxes and radiative terms. Observations of vertical fluxes of heat, salt and momentum between the ocean interior and surface are important to our understanding and modeling of processes that maintain perennial ice cover in the Arctic, particularly at a time of such rapid changes in ice coverage and volume. Underway alterations of the Arctic system, in particular of its thermodynamic balance, may be precursory indicators of more widespread changes to come. Yet the observations to fully document such processes are lacking. To begin to address this measurement gap, it is proposed to deploy 4 ocean flux buoys each year for a four years. This award funds the first year of the expanded deployment while the network design takes place under the auspices of SEARCH and the International Polar year (2007-2008). The work will be conducted with other researchers who will make complimentary, co-located observations and share logistic costs which would otherwise be overwhelming. This co-operative approach was discussed and recommended by participants of the international workshop Arctic Observing Based on Ice-Tethered Platforms.
