Sci Rep
. 2020 Nov;
10(1):20671.
PMID: 33244124
The relevance of CO emissions from geological sources to the atmospheric carbon budget is becoming increasingly recognized. Although geogenic gas migration along faults and in volcanic zones is generally well...

Sci Rep
. 2020 Aug;
10(1):13187.
PMID: 32764641
Sources of particulate organic carbon (POC) play important roles in aqueous carbon cycling because internal production can provide labile material that can easily be turned into CO. On the other...
