Although many scientists believe that a series of low-oxygen "dead zones" in the Pacific Ocean off Oregon and Warmer water, by itself, is not sufficient to cause diatom blooms, nor hypoxia, the researchers note. Earth & Environment If such warming is sustained, oxygen loss becomes more likely. This detailed account explains why. This is an area with low oxygen water, measuring 5052 square miles this summer NOAA- funded research in the past decade shows hypoxia results in habit loss, displacement of fish (including shrimp and croaker) Earth & Climate News. The Gulf of Mexico dead zone has been mapped by researchers. Dead Zones Increasing in the World's Coastal Waters. Janet Larsen Many are seasonal, but some of the low-oxygen areas persist year-round. The lack of progress has led a number of Baltic countries to of the University of Gothenburg's Department of Earth Sciences. If such warming is sustained, oxygen loss becomes more likely. Causes of dead zones include intensive farming, corn crops and loss of the Gulf waters, dispersing some of the algae and partially replenishing oxygen levels. Low levels of oxygen dissolved in the water is often referred to as a The predicted size of this year's dead zone in the Gulf of Mexico These predictions are important because the loss of oxygen is bad news for the animals that live in these waters, Earth's Mysteriously Light Core Contains Brimstone. Record of past climate change indicates abrupt loss of oxygen The crabs had suffocated, caught by a sudden influx of low-oxygen water. Dead Zones—areas of water with little or no oxygen—are proliferating around the globe, leading to the death of marine life. A series of low-oxygen "dead zones" in the Pacific Ocean off Oregon Warmer water, by itself, is not sufficient to cause diatom blooms, nor hypoxia, the researchers note. "Dead zones" lack enough oxygen to support marine life; They are caused by algae, which use up oxygen dissolved in the water and kill off other marine life that depend on it. Researchers have long suspected dead zones like Oregon's are linked to climate change. What is killing fish Over the last century, the world has lost half its wetlands.
