Extensive sea ice covered the world's oceans during the last ice age, preventing oxygen from penetrating into deep ocean waters and complicating the relationship between oxygen and carbon, a new study...
For more than seven years, a mysterious wasting disease has nearly killed off sea star populations worldwide. Many of these species are at the brink of extinction.New Cornell University-led resea...
Scientists at the Scripps Institution of Oceanography at the University of California, San Diego, have found that low oxygen levels in seawater could blind some marine invertebrates.The results, publi...
A new analysis of decades of data on oceans across the globe has revealed that the amount of dissolved oxygen contained in the water – an important measure of ocean health – has been declining for mor...
A reduction in the amount of oxygen dissolved in the oceans due to climate change is already discernible in some parts of the world and should be evident across large regions of the oceans between 203...
Can animals thrive without oxygen?     animals  thrive  oxygen       2016/2/22
In 2010, a research team garnered attention when it published evidence of finding the first animals living in permanently anoxic conditions at the bottom of the sea. But a new study, led by scientists...
A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic, conditions that led to vast marine dead zones.Results of the re...
For over 50 years, the ocean science community has traditionally reported hypoxic limits for marine animals simply as a concentration value independent of temperature and pressure, implying the same l...
The oxygen concentration in the ocean is controlled by a delicate balance between the source from atmosphere-ocean interaction and net respiration of organic matter after the water leaves the surface ...
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It’s the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest c...
Seafloor sediment cores reveal abrupt, extensive loss of oxygen in the ocean when ice sheets melted roughly 10,000-17,000 years ago, according to a study from the University of California, Davis. The ...
We investigated the production, consumption, and exchange of O2 in melting sea ice to assess the biological- and physical-induced O2 turnover. The underside of the ice was covered with 5–20 cm3 large,...
Metabolic enzyme activities and gill surface areas were measured across 10 species of demersal fishes from Monterey Canyon, California, which features a prominent oxygen minimum zone (OMZ). Comparison...
The concentration of oxygen in the deep Strait of Georgia has declined at a rate of 0.45–1.3 mmol L21 yr21 since 1971 and now seasonally approaches thresholds of biological tolerance. The decline ha...
