Profiling Floats in the Arctic Ocean: Development and Field Test During the Beringia 2005 Cruise

调查人员将开发和测试能够在北冰洋的离散深度或恒定密度水平上跟随洋流的剖面浮标。漂浮物将在他们取样的水柱的哪个部分是灵活的。在夏末，当线索充足时，浮标将上升到水面，通过卫星传输存储的数据，之后它们可能会下降，进行下一年的任务，重复这个循环长达3-5年。在这项拨款期间，漂浮和遥测技术将作为2005年泛北极白令陆桥巡航的一部分进行测试。开发和实地测试将是对概念的验证，一旦成功，将为今后国际极地年及以后在整个北冰洋上开发浮标开辟道路。

The investigators will develop and test profiling floats capable of following currents in the Arctic Ocean at a discrete depth or on a level of constant density. The floats will be flexible in what part of the water column they sample. In late summer, when leads are plentiful, the floats will rise to the surface to transmit the stored data via satellite, after which they may descend for another year's mission, repeating this cycle for up to 3-5 years. During the period of this grant, float and telemetry techniques will be tested as part of the pan-Arctic Beringia 2005 cruise. The development and field test will be a proof of concept, and upon success, will lead the way to future developments of floats throughout the Arctic Ocean for the International Polar Year and beyond.
