| 摘 要： | 基于2008年中国第三次北极科学考察的CTD数据,研究了北冰洋加拿大海盆的双扩散现象.双扩散对流导致的阶梯状均匀混合在加拿大海盆广泛存在,在加拿大中央海盆及门捷列夫海脊观测到了明显的双扩散阶梯.阶梯结构在深度分布上有显著的空间差异,在100～500 m深度范围内都可能存在双扩散阶梯,稳定的阶梯结构位于温跃层所在深度,阶...

| Abstract: | Double-diffusive staircase structure is investigated with CTD profile data in the Canadian Basin obtained from the third Chinese Arctic Expedition in summer of 2008.There exist extensive double-diffusive mixed phenomena in the Canadian Basin.Double-diffusive staircase is observed in the central Canada Basin and Mendeleyev Ridge.The distribution of double-diffusive staircase has significant spatial difference.There exists double-diffusive staircase through the depth range of 100~500 m.The 1 m to 5 m high sta... |
