Pacific Coast Dead Zones

Pacific Coast Dead Zones

Climate change affects coastal currents that moderate ocean temperatures and the productivity of ecosystems. As such, it is believed to be a factor in the low-oxygen “dead zone” that has appeared along the coast of Washington and Oregon in recent years.1 In the maps above, blue indicates low-oxygen areas and purple shows areas that are the most severely oxygen depleted.  Image References: PISCO; NOAA-NWFSC; OSU/COAS2
