This proposal is part of an integrated scientific investigation to study the properties of the Arctic ocean, atmosphere, and sea- ice on a transect between Murmansk, USSR and Nome, Alaska. It will assess the quantity and character of sediments contained in the ice canopy of the Arctic Basin. This investigation will evaluate the effects of sediment on the reflectivity, thermal balance, transmissivity, and sub-ice biology. The presence and nature of sediments on sea ice may also shed light on the dynamics of ice movement and the relationships between sea-ice cover and sediment accumulations on the ocean floor.

该提案是一项综合科学研究的一部分，该研究研究了北极海洋，大气和海冰在阿拉斯加的穆尔曼斯克和诺姆姆之间的样品上的特性。 它将评估北极盆地冰篷中包含的沉积物的数量和特征。 这项研究将评估沉积物对反射率，热平衡，透射率和亚冰生物学的影响。 沉积物在海冰上的存在和性质也可能阐明冰的动力以及海冰覆盖物与沉积物在海底积聚之间的关系。
