拉普特夫陆架冬季海冰净生产量(NSIP)是根据20世纪60年代至90年代连续的夏季至冬季历史盐度记录推断的。虽然NSIP强烈依赖于假定的新形成冰的盐度，但NSIP的准年代际变化可以与拉普特夫海区的风生环流异常联系起来。当北极涛动(AO)为正值时，拉普特夫海岸线以外的风驱动的平流增加，这意味着沿海波尼亚海冰的生产和陆架水中卤水的释放增加。当AO为负值时，NSIP和季节盐度幅度有减弱的趋势。这些结果与海冰观测和模拟结果是合理一致的。
The winter net sea‐ice production (NSIP) over the Laptev Sea shelf is inferred from continuous summer‐to‐winter historical salinity records of 1960s–1990s. While the NSIP strongly depends on the assumed salinity of newly formed ice, the NSIP quasi‐decadal variability can be linked to the wind‐driven circulation anomalies in the Laptev Sea region. The increased wind‐driven advection of ice away from the Laptev Sea coast when the Arctic Oscillation (AO) is positive implies enhanced coastal polynya sea‐ice production and brine release in the shelf water. When the AO is negative, the NSIP and seasonal salinity amplitude tends to weaken. These results are in reasonable agreement with sea‐ice observations and modeling.
