The rapid expanding oxygen minimum zones in global oceans over the past 60 years has been observed
Date:2022/04/01

Recently, Yuntao Zhou’s research group has published a research paper entitled “Responses of Horizontally Expanding Oceanic Oxygen Minimum Zones to Climate Change Based on Observations” in Geophysical Research Letters.

Expanding oxygen minimum zones (OMZs, low dissolved oxygen [DO] zones) in the open ocean have been the topic of intense interest, which greatly affect marine organisms, community composition, habitats, as well as change biogeochemical cycles. Previous studies have examined the OMZ range on regional scales or vertical sections. However, annual OMZ areas, trends in OMZ areas, and causes of OMZ expansions remain unclear. Our paper explores the locations and annual areas of global and regional OMZ areas based on observations from 1960 to 2019.
