位于阿拉斯加巴罗海岸和巴罗峡谷东侧之间的近海地区是太平洋水流从轴承海峡流向北极盆地的重要位置。在冬季，该地区被冰覆盖，很难用常规技术进行水文观测。该区域的长度尺度和水深非常适合小型螺旋桨驱动的自主水下航行器（auv）的能力。为了准备使用水下航行器在冬季测量冰下的水文条件，进行了一系列的活动：2005年夏天，在为期两周的时间里，研究人员利用AUV测量了巴罗点近海的温度、盐度和洋流，并进行了导航试验，以记录AUV的航位推断性能，并于2008年3月进行了一次实地调查，以评估表面冰况和地下声波测距性能。
The region offshore of Barrow, Alaska, between the coast and the eastern flank of Barrow Canyon is an important location along the pathway of Pacific Water flowing from the Bearing Strait to the Arctic Basin. In winter, the region is ice covered and hydrographic observations are difficult to obtain using conventional techniques. The length scales and water depths in this region are well suited to the capabilities of small, propeller driven autonomous underwater vehicles (AUVs). A series of activities were undertaken in preparation for use of an AUV to measure hydrographic conditions beneath the ice in winter: A pilot study using an AUV to measure temperature, salinity and currents offshore of Point Barrow was carried out over a period of two weeks in the summer of 2005, navigation trials were conducted to document the dead-reckoning performance of the AUV, and a field survey was conducted in March 2008 to assess surface ice conditions and subsurface acoustic ranging performance.
