摘要

摘要: 渤海一年冰的组构和晶体结构表现出的冰的非连续生长速率使得冰层底部具有气泡含量不同的许多分层;静水生长的灰冰具有典型的粒状冰和柱状冰;融化-重冻结冰和重叠冰具有特定的晶体结构.位于北冰洋72°24.037'N,153°33.994'W,长2.2m的冰心样为三年冰,并且发现其内有一种新的晶体类型,定义为碎屑凝聚冰.由位于北冰洋74°58.614'N,160°31.830'W,长4.86m的冰心样的晶体结构分析发现它过去为冰脊,后经融化-冻结改造形成冰丘的证据.

Abstract: The fabrics and crystals of one year ice in the Bohai Sea show that the noncontiguous ice growth rate makes an ice sheet have level layers with different amount of air bubbles in lower part of the ice sheet; typical grain ice and columnar ice occur in the gray ice which grows in stable water; thaw-refrozen ice and rafted ice have their crystal characteristics.On the Arctic sea ice, the 2.2 m long ice core located at 72°24.037'N, 153°33.994'W is a three year ice floe, and a new sort of crystal is found, which is defined as refrozen clastic pieces.The crystal profile of the ice core (its length is 4.86 m) located at 74°58.614'N, 160°31.830'W shows the evidence of an ice ridge changed into hummock.
