Coastal Researchers, Fishermen Concerned About More Frequent Low Oxygen Zones
Description: Scientists in Oregon and Washington are noticing a disruptive ocean phenomenon is becoming more frequent and extreme. It involves a suffocating ribbon of low oxygen seawater over our continental shelf. The technical term is hypoxia, sometimes called "dead zones." It's an unwelcome variation on normal upwelling of cold, nutrient rich water from the deep ocean. When the dissolved oxygen drops too low, it drives away fish and can suffocate bottom dwellers such as crabs and sea worms who can't scurry away fast enough.
