Sea ice oxygen reaching deep ocean during ice age
2021/2/25
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...
Decades of Data on World’s Oceans Reveal a Troubling Oxygen Decline
Decades of Data World’s Oceans Oxygen Decline
2017/5/3
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...
Widespread loss of ocean oxygen to become noticeable in 2030s
Widespread loss ocean oxygen noticeable in 2030s
2016/4/27
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...
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...
Low-oxygen 'dead zones' in North Pacific linked to past ocean warming
Low-oxygen dead zones North Pacific ocean warming
2015/11/18
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...
A Plea for Temperature in Descriptions of the Oceanic Oxygen Status
Temperature in Descriptions Oceanic Oxygen Status
2015/7/17
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...

Smothered oceans Extreme oxygen loss oceans accompanied past global climate change
2015/1/28
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 ...
Biological- and physical-induced oxygen dynamics in melting sea ice of the Fram Strait
Biological- and physical-induced oxygen dynamics melting sea ice Fram Strait
2014/7/10
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,...
