Climate and human-driven variability of summer hypoxia on a large river-dominated shelf as revealed by a hypoxia index
Because these indirect factors influence hypoxia via direct pathways, we must disentangle the contributions of the direct drivers in order to quantify the contributions of climate change and human activities and to delineate the pathways impacting the long-term variation of coastal hypoxia. The mean thickness of the hypoxia area is the averaged vertical distance between β
