Climate model predictions1,2 and observations3,4 reveal regional declines in oceanic dissolved oxygen, which are probably influenced by global warming5. Studies indicate ongoing dissolved oxygen depletion and vertical expansion of the oxygen minimum zone (OMZ) in the tropical northeast Atlantic Ocean6,7. OMZ shoaling may restrict the usable habitat of billfishes and tunas to a narrow surface layer8,9. We report a decrease in the upper ocean layer exceeding 3.5ml l−1 dissolved oxygen at a rate… CONTINUE READING
