巴罗附近的积雪结构在2009年3月至4月进行了研究。测量了冻原、湖泊和陆固冰的密度、比表面积(SSA)和热导率的垂直剖面。冻土层平均厚度为41厘米,固定冰平均厚度为21厘米。观察到的地层为顶部的金刚石尘或近期风积物、覆盖的风板、偶尔出现的刻面晶体和融冻结壳,以及底部深度为45 - 224 m的灰白层
The structure of the snowpack near Barrow was studied in March–April 2009. Verticalprofiles of density, specific surface area (SSA) and thermal conductivity were measuredon tundra, lakes and landfast ice. The average thickness was 41 cm on tundra and 21 cmon fast ice. Layers observed were diamond dust or recent wind drifts on top, overlayingwind slabs, occasional faceted crystals and melt-freeze crusts, and basal depth hoar layers.ThetoplayerhadaSSAbetween45and224m
