Low-oxygen 'dead zones' in North Pacific linked to past ocean warming
Low-oxygen dead zones North Pacific ocean warming
2015/12/7
A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic, conditions that led to vast marine dead zones.Results of the re...
