Virtually all oxygen on Earth was and is produced by photosynthesis, which was invented by tiny organisms, the cyanobacteria, when our planet was still a rather uninhabitable place.
On May 14, the National Oceanic and Atmospheric Administration (NOAA) ship Okeanos Explorer will depart from Port Canaveral in Florida on a two-week expedition led by NOAA Ocean Exploration, featuring […]
Oxygen is essential for the development of higher life. However, it was hardly present in the oceans of the young Earth. It was not until the evolution of photosynthetic bacteria […]
A team led by University of Minnesota researchers has discovered that deep-sea bacteria dissolve carbon-containing rocks, releasing excess carbon into the ocean and atmosphere. The findings will allow scientists to […]
In Kevin Hand’s “Alien Oceans: The Search For Life In The Depths Of Space” we learn that Earth is just one example of a myriad ways that a world can […]
Dale Andersen: A quick video tour of Lake Untersee using drone footage I captured including views of our camp, a drive across the lake from our camp to the pressure […]
Around 120 million years ago, the earth experienced an extreme environmental disruption that choked oxygen from its oceans. Known as oceanic anoxic event (OAE) 1a, the oxygen-deprived water led to […]
With no dissolved oxygen to sustain animals or plants, ocean anoxic zones are areas where only microbes suited to the environment can live. “You don’t get big fish,” said UC […]
The hypothesis that one or more biodiversity drops in the Phanerozoic eon, evident in the geological record, might have been caused by the most powerful kind of stellar explosion so […]
We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar properties.
