Past occurrences of hypoxia in the Baltic Sea and the role of climate variability, environmental change and human impact
TL;DR: The hypoxic zone in the Baltic Sea has increased in area about four times since 1960 and widespread oxygen deficiency has severely reduced macro benthic communities below the halocline in the Balti...
