Oxygen rise in the tropical upper ocean during the Paleocene-Eocene Thermal Maximum
The global ocean's oxygen inventory is declining in response to global warming, but the
future of the low-oxygen tropics is uncertain. We report new evidence for tropical …

Expansion of ocean anoxia during glacial periods recorded in the cobalt flux to pelagic sediments
NJ Hawco, RK Foreman - Geophysical Research Letters, 2023 - Wiley Online Library
The expansion of oxygen deficient zones (ODZs) within the ocean's interior is anticipated to
be a major consequence of anthropogenic climate change, but past changes in ODZs are …

Coral photosymbiosis on Mid-Devonian reefs
The ability of stony corals to thrive in the oligotrophic (low-nutrient, low-productivity) surface
waters of the tropical ocean is commonly attributed to their symbiotic relationship with …
