DOI: 10.1016/j.orggeochem.2021.104287
Abstract: Abstract Amazon rivers and flooded areas can be categorized into three types of water: white, black, and clear. These categories present unique physical–chemical characteristics that influence the characteristics and distribution of sedimentary organic matter (SOM).… read more here.

DOI: 10.1038/ncomms14379
Abstract: It is unclear why atmospheric oxygen remained trapped at low levels for more than 1.5 billion years following the Paleoproterozoic Great Oxidation Event. Here, we use models for erosion, weathering and biogeochemical cycling to show… read more here.
