Abstract

A hypoxic zone with dissolved oxygen concentrations of 3.0–3.6 mL/L (42–51% saturation) was first discovered in the bottom depression in the Srednyaya Cove (between the Pushchin and Pashinnikov capes) in Vostok Bay in July–September 2021. It existed from mid-July to mid-September. It was revealed that the surveyed area was characterized by high concentrations of phosphates at bottom horizons and organic carbon in sediments. It was shown that the formation of the hypoxic zone occurred as the result of an increase in the anthropogenic impact on this sea area.

首次发现东方湾（日本海）缺氧现象

摘要 2021 年 7 月至 9 月，在沃斯托克湾的斯雷德尼亚海湾（普什琴海角和帕申尼科夫海角之间）海底洼地首次发现了溶解氧浓度为 3.0-3.6 mL/L（饱和度为 42-51%）的缺氧区。它存在于 7 月中旬至 9 月中旬。调查显示，调查区域的特点是底层磷酸盐浓度高，沉积物中有机碳含量高。研究表明，缺氧区的形成是该海域人为影响增加的结果。
