A new study suggests that some of the world’s oxygen-deprived oceans could eventually regain higher oxygen levels in the ...

Projections of our future under climate change paint a picture of extreme weather and acidified oceans, a world many of today’s animals — including humans — may struggle, or fail, to survive. Yet ...

PLATE 1. Figures 1–4: Carcharhinus amblyrhynchoides (DGCUSB/BB-115,112), upper antero-lateral, Figures 5–6: Carcharhinus brevipinna (DGCUSB/BB-136), upper tooth, Figures 7–10: Carcharhinus perezi ...

This revelation challenges the conventional wisdom that more heat equals less oxygen in marine environments. The study indicates that ocean circulation patterns and local winds, such as monsoons, may ...

These fossils, collected from sediment cores provided by the Ocean Drilling Program, contain chemical signatures that allow scientists to estimate historical oxygen levels in seawater over millions of ...

Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though ...

The Miocene is a geologic epoch of the Neogene Period, spanning approximately 23.03 to 5.33 million years ago, characterized by significant tectonic, climatic, and biotic transitions. It saw continued ...
