Sentences with phrase «ocean anoxia»

«These low oxygen levels (called ocean anoxia) help trigger the conditions needed for making fossil fuels like oil and coal in the first place.

Typically, scientists determine ocean anoxia levels by looking at the abundance of pyrite, commonly known as «fool's gold,» and other elements and minerals in ancient mud rocks.

Thus, metal toxicity, and its expressions in fossilized malformations, could provide the «missing link» that relates organism extinctions to widespread ocean anoxia.

It seems accumulating CO2 unleashed positive feedbacks, causing ocean anoxia and water temps which could have supported «hypercanes.»

In particular, the team wanted to see if separate episodes of extinction that happened during the long period of recovery were driven by episodes of ocean anoxia and other environmental changes.

These low oxygen levels (called ocean anoxia) help trigger the conditions needed for making fossil fuels like oil and coal in the first place.

They were able to show that episodes of extinction coincided with pulses of ocean anoxia, driven by changes in ocean circulation and nutrient levels.

That would be wonderful if at least Atlantic TC reduce or do not increase with GW, since GW is and will be doing so much greater harm thru droughts, floods, disappearing glaciers, disease spread, ocean anoxia (with HS outgassing likely to follow), species loss, heat deaths,... am I leaving anything out?

Hence CO2 ramped up ever faster in the atmosphere, further accelerating warming, until you have the same symptoms of a global - warming - mass - extinction like the end Triassic or even Permian (ocean acidification, jump in global temperatures, ocean anoxia, etc).

Enormous disruptions of the carbon cycle led to climate change, ocean acidification and ocean anoxia — and with an estimated 90 percent of all species dying out Earth almost... Continue reading →

The team's analysis published in full in the journal Science Advances has revealed that the episodes of mass extinction coincided with episodes of ocean anoxia, which resulted from changes in ocean circulation and nutrient levels in the Early Triassic.

For more than 25 years, ocean anoxia has been invoked a major cause of the Late Permian mass extinction event, and it is also inferred to have been a key control on the patterns and duration of biosphere recovery.
