南极西部半岛（WAP）是一个生产力很高的海洋生态系统，在那里观察到冰川退缩、海冰覆盖减少和海洋种群变化等形式的长期变化。众所周知，大陆架上的物理环境受到下列因素的强烈影响：沿大陆架斜坡流动并携带温暖、营养丰富的水的南极绕极流、从威德尔海涌入布兰斯菲尔德海峡北部的冷水、广泛的冰川和冰架网络、海冰形成和海气相互作用的强烈季节性和年际变化。受到El Niño-Southern涛动和南环模等气候模式的显著调制。然而，在了解开放海洋与大陆架之间的交换过程、海水入侵的途径和命运、大陆架热盐收支以及大陆架性质和环流的长期演变方面仍存在重大差距。在这里，我们回顾了长期监测计划、过程研究和新开发的数值模型的最新进展如何帮助弥合这些差距，并为WAP系统设定了未来的研究挑战。本文是“南极半岛西部海洋体系：快速变化地区的现状与发展战略”主题的一部分。
The West Antarctic Peninsula (WAP) is a highly productive marine ecosystem where extended periods of change have been observed in the form of glacier retreat, reduction of sea-ice cover and shifts in marine populations, among others. The physical environment on the shelf is known to be strongly influenced by the Antarctic Circumpolar Current flowing along the shelf slope and carrying warm, nutrient-rich water, by cold waters flooding into the northern Bransfield Strait from the Weddell Sea, by an extensive network of glaciers and ice shelves, and by strong seasonal to inter-annual variability in sea-ice formation and air–sea interactions, with significant modulation by climate modes like El Niño–Southern Oscillation and the Southern Annular Mode. However, significant gaps have remained in understanding the exchange processes between the open ocean and the shelf, the pathways and fate of oceanic water intrusions, the shelf heat and salt budgets, and the long-term evolution of the shelf properties and circulation. Here, we review how recent advances in long-term monitoring programmes, process studies and newly developed numerical models have helped bridge these gaps and set future research challenges for the WAP system. This article is part of the theme issue ‘The marine system of the West Antarctic Peninsula: status and strategy for progress in a region of rapid change’.
