Article Synopsis
- The ocean has lost significant oxygen over the past decades, impacting marine life and fisheries, with historical events like the Paleocene-Eocene Thermal Maximum (PETM) providing valuable insights into future deoxygenation patterns.
- Research from South Atlantic sediment cores indicates a decrease in foraminifera-bound nitrogen and an increase in marine barite sulfur, suggesting a shift towards more oxygen-deficient zones (ODZs) during the PETM, characterized by ammonium and sulfide build-up.
- Modeling shows that warming in the Southern Ocean and heightened productivity led to "ammonium-type" ODZs, while different oxygenation conditions in the Pacific suggest that the consequences of global warming on ocean deoxygenation
Despite the harsh environmental conditions in the world's oldest and driest desert, some salt flat or 'salar' environments in the Atacama Desert host standing bodies of water known as saline lakes. Evaporite minerals deposited within saline lakes result from the equilibrium of environmental, sedimentological, and biogeochemical processes that occur in the salar; consequently, these minerals are sensitive records of human activities and ecological, evolutionary, and geological changes. The objective of this study was to evaluate feedbacks between physical, chemical, and microbial processes that culminate in distinct trends in brine chemistry, saline lake morphology, and associated evaporite sediments.
