溶解氧不足（缺氧）的季节性发展代表了对地球仪周围沿海生态系统的生态动态和渔业可持续性的急性系统级扰动（1-3）。尽管人为营养负荷增加了河口和半封闭海缺氧的频率和严重程度（3，4），但开放海岸上升流系统中缺氧的发生反映了控制向大陆架输送贫氧和富营养深水的海洋条件（1）。上升流系统支撑着世界上很大一部分的渔业（5），因此了解海洋气候变化，上升流驱动的缺氧和生态扰动之间的联系至关重要。在这里，我们报告了前所未有的发展严重内架（
Seasonal development of dissolved-oxygen deficits (hypoxia) represents an acute system-level perturbation to ecological dynamics and fishery sustainability in coastal ecosystems around the globe(1-3). Whereas anthropogenic nutrient loading has increased the frequency and severity of hypoxia in estuaries and semi-enclosed seas(3,4), the occurrence of hypoxia in open-coast upwelling systems reflects ocean conditions that control the delivery of oxygen-poor and nutrient-rich deep water onto continental shelves(1). Upwelling systems support a large proportion of the world's fisheries(5), therefore understanding the links between changes in ocean climate, upwelling-driven hypoxia and ecological perturbations is critical. Here we report on the unprecedented development of severe inner-shelf (
