Dead zones formed repeatedly in North Pacific during warm climates
An analysis of sediment cores from the Bering Sea has revealed a recurring relationship between warmer climates and abrupt episodes of low-oxygen ‘dead zones’ in the subarctic North Pacific Ocean over the past 1.2 million years. The findings provide crucial information for understanding the causes of low oxygen or ‘hypoxia’ in the North Pacific and for predicting the occurrence of hypoxic conditions in the future. …read more
