基于我国第七次北极科学考察—2016年夏季北极海冰厚度观测与特征分析
Arctic sea ice observation and characteristic analysis based on the seventh National Arctic Research Expedition in summer 2016
摘要
Abstract
The National Marine Environmental Forecasting Center has participated in the Seventh National Arctic Research Expedition in summer 2016 and completed 36 sections observation at 7 ice stations.The investigation work includes EM31 ice thickness observation,snow thick manual observation and artificial drilling ice thickness observation.Compared the sea ice thickness that measured by EM31 with by manual drilling measurement,the average error of EM31 measured ice thickness is 14.5 cm which is at the allowable error range,indicating that EM31 is suitable for ice thickness observation.The average sea ice thickness of seven ice stations is from 57 cm to 246 cm.The spatial distribution of ice thickness is very uneven.The relief degree of sea ice surface between each ice stations is varied greatly.Research results in the paper indicates that the Arctic sea ice is affected mainly by external force.When the ice reached at a certain thickness,the sea ice roughness and relief degree of sea ice surface is depended mainly on the extent of external squeezing and its intrinsic hardness.关键词
