描述了德文郡岛冰帽的堆积模式。冰帽最高处周围有一个最小堆积区，高度为100 - 200米。在这一区域之下，积累逐渐增加，在冰盖边缘附近达到最大值。整体格局与下降风的降雪运输有关。高积累的区域积累模式（约。40.0厘米水当量）在冰盖的东南部和低积累区（约。110厘米。（水）在西北部。这种由东-东南-东向西-西北-西的累积梯度与巴芬湾东部的气旋活动有关，可能由于同一地区存在开阔水域而加剧。
The pattern of accumulation on the Devon Island ice cap is described. There is an area of minimum accumulation encircling the highest part of the ice cap and 100–200 m. below it. Below this zone, accumulation gradually increases to a maximum near the ice-cap edge. The overall pattern is related to snow transport by katabatic winds. There is a regional accumulation pattern of high accumulation (ca. 40.0 cm. water equivalent) in the south-east part of the ice cap and an area of low accumulation (ca. 11 0 cm. water equivalent) in the north-west. This east-south-east to west-north-west accumulation gradient is related to cyclonic activity to the east in Baffin Bay, and it is probably intensified by the presence of open water in the same area.
