The fear is that melting ice, along with increased snow and rain, could reduce the density and salinity of the top layers of the sea, making them more buoyant.

人们担忧的是正在融化的冰和不断增加的雨雪可能降低海洋表层水体的密度和盐度，导致其更容易滞留在海洋表层。

The higher the ratio (known, confusingly, as the density, even though bigger Numbers mean the snow is actually less dense), the drier and more powdery the snow.

该比率越高，积雪会越干燥和越像粉状(虽然该比率被称为是密度，但是其数字越大代表密度越低)。

The density of white shingles is greatest towards the top of the climbing tower, suggestive of snow, while grey and brown shingles surround the base.

白色瓦片的密度在攀岩塔的顶部是最大的，象征着雪，而灰色和棕色的瓦片环绕在底部。

One-hundred-and-two holes have been dug so far and 1, 100 measurements have been made of ice thickness, snow density and other features - data deemed vital by scientists evaluating the future of the Arctic sea-ice.

Climatologists say 12 inches of snow is equivalent to about 1 inch of rain, depending on the density of the snow.
