Hypoxia - Gulf of Mexico (GCOOS)

Hypoxia in aquatic systems refers to waters where the dissolved oxygen concentration is below 2 mg/L. Most organisms avoid, or become physiologically stressed, in waters with oxygen below this concentration. Also known as a dead zone, hypoxia can also kill marine organisms which cannot escape the low-oxygen water, affecting commercial harvests and the health of impacted ecosystems. Data are from the Gulf of Mexico Hypoxia Watch (https://www.ncddc.noaa.gov/hypoxia/products/)水生系统中的低氧（Hypoxia）指溶解氧浓度低于2 mg/L的水体。绝大多数水生生物会规避此类低氧水体，或在此环境下产生生理应激反应。低氧又被称为死亡区（dead zone），无法逃离低氧水环境的海洋生物会因此死亡，进而影响商业捕捞业以及受影响生态系统的健康。本数据集数据源自墨西哥湾低氧观测项目（Gulf of Mexico Hypoxia Watch），数据链接为：https://www.ncddc.noaa.gov/hypoxia/products/
