New Study Reveals Asynchronous Land–ocean Responses To Ancient Ocean Anoxia
Earth experienced a period of intense, large-scale volcanism during the early Aptian. Around that time, it also experienced widespread ocean deoxygenation during the Oceanic Anoxic Event 1a (OAE1a) as well […]

The Water Makeup Of Jupiter’s Galilean Moons Was Set At Birth
While Io, the most volcanically active moon in the solar system, appears completely dry and devoid of water ice, its neighbor Europa is thought to harbor a vast global ocean […]
