补充资料:海冰
海冰 sea ice 海洋中冻结而成的咸水冰 。广义的海冰还包括在海洋中的河冰、冰山等。最初形成的海冰是针状的或薄片状的,随后聚集和凝结,并在风力、海流、海浪和潮汐的作用下,互相堆叠而成重叠冰和堆积冰。一般情况下都浮于海面,形状规则的海冰露出水面的高度为总厚度的1/7~1/10,尖顶冰露出的高度达总厚度的 1/4~1/3。反射率为0.50~0.70,抗压强度约为淡水冰的3/4。海冰可分为两类:①固定冰。多分布在大陆沿岸或岛屿附近,与海岸、岛屿,甚至与海底冻结在一起。②浮冰或冰山。随风、浪、流而漂移。 海冰在极地的分布具有显著的季节性变化和年际变化。①北半球。冰界以3~4月最大,8~9月最小。北冰洋几乎全为冰所覆盖,流冰群主要绕洋盆边缘流动,多为3~4米厚的多年冰。②南半球。多为2~3米厚的、到了夏天就能融化的冰,大致呈纬向分布,冰区以9月(属冬天)最大,3月(属夏天)最小。固定冰分布南极大陆周围和威德尔海。浮冰冰界在南太平洋、南印度洋和南大西洋。分别在南纬50°~55°、南纬45°~55°和南纬43°~55°。 |
