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.

调查人员将开发和测试能够在离散深度或恒定密度水平上跟踪北冰洋洋流的剖面浮标。在对水柱的哪一部分进行采样方面，浮标将是灵活的。在夏末，当铅丰富时，浮标会浮到水面，通过卫星传输存储的数据，之后它们可能会下降到另一年的任务中，重复这个周期长达3-5年。在这笔赠款期间，浮标和遥测技术将作为2005年泛北极贝林吉亚邮轮的一部分进行测试。开发和实地测试将是对概念的验证，一旦成功，将引领整个北冰洋未来开发国际极地年及以后的浮标。
