Variations in atmospheric oxygen levels shaped Earth’s climate through the ages
oxygen levels Earth’s climate
2015/6/18
Variations in the amount of oxygen in Earth's atmosphere significantly altered global climate throughout the planet's history. Efforts to reconstruct past climates must include this previously overloo...
The period of extended low oxygen, which spanned from roughly 2 to less than 1 billion years ago, was a time of remarkable chemical stability in the Earth's oceans and atmosphere. A University of Cali...
Atmospheric oxygen and carbon dioxide observations from two European coastal stations 2000–2005: continental influence, trend changes and APO climatology
Atmospheric oxygen carbon dioxide European coastal APO climatology
2010/2/21
Seeking for baseline conditions has biased the atmospheric carbon dioxide (CO2) and later on also oxygen (O2) monitoring networks towards remote marine stations, missing part of the variability that i...
Detection of regional scale sea-to-air oxygen emission related to spring bloom near Japan by using in-situ measurements of the atmospheric oxygen/nitrogen ratio
sea-to-air oxygen emission spring bloom Japan atmospheric oxygen/nitrogen ratio
2008/11/11
We have been carrying out in-situ monitoring of atmospheric O2/N2 ratio at Cape Ochi-ishi (COI; 43°10' N, 145°30' E) in the northern part of Japan since March 2005 by using a modified gas chromatograp...
Anomalous flow below 2700 m in the EPICA Dome C ice core detected using δ18O of atmospheric oxygen measurements
EPICA Dome C ice core atmospheric oxygen
2008/11/6
While there are no indications of mixing back to 800 000 years in the EPICA Dome C ice core record, comparison with marine sediment records shows significant differences in the timing and duration of...
