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.

这是一项继续在北极中部部署的建议，并将在浮冰上的自主海洋通量浮标的部署扩大到西部北极，使用共置的仪器测量T/S剖面、冰通量和包括大气总体通量和辐射项在内的地表强迫。对海洋内部和表面之间的热量、盐分和动量垂直通量的观测对于我们理解和模拟维持北极常年冰盖的过程非常重要，特别是在冰盖和冰量迅速变化的时候。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先兆。然而，缺乏对这些过程进行全面记录的观察。为了开始解决这一测量差距，建议在四年内每年部署4个海洋通量浮标。该奖项为扩大部署的第一年提供资金，而网络设计是在Search和国际极地年(2007-2008)的赞助下进行的。这项工作将与其他研究人员一起进行，他们将进行免费的、共同定位的观察，并分担后勤成本，否则这将是压倒性的。基于冰系留平台的北极观测国际讲习班的与会者讨论并建议采取这种合作办法。
