要旨 Abstract：Some models predict expansion of oceanic oxygen minima
 with future global warming.  Seasonal or interannual dead zones
 have been discovered recently off Chile and Oregon, although it is
 unclear whether these are unique new phenomena or a recent
 manifestation of natural variations.  Paleoceanographic records
 reveal episodes of hypoxia around the Pacific Rim, offer insight
 into mechanisms and natural variations of changing oxygen
 concentration in the oceans related to watermass ventilation and
 biological productivity, and provide useful targets for testing and
 improving models that include biogeochemical processes.
