Scientists examined rock cores taken from the Chicxulub crater in Mexico, site of the asteroid impact that triggered dinosaur extinction, and found iridium, a telltale sign of asteroids.
(University of Rhode Island) Research conducted by scientists at the University of Rhode Island published today in Nature Communications found that microbes living in ancient sediment below the seafloor are sustained primarily by chemicals created by the natural irradiation of water molecules. Results of this research may have implications for life on Mars.
As more and more plastic trash permeates the oceans, microplastics are making their way into fish and shellfish, and potentially into humans.
Seismologists studying earthquake activity off the US coast recorded fin whale songs, which they found can be used to tell the thickness and makeup of Earth’s crust
(University of Hawaii at Manoa) A team of scientists from NOAA’s Pacific Islands Fisheries Science Center, the University of Hawai’i at Mānoa, Arizona State University and elsewhere have discovered that a diverse array of marine animals find refuge in so-called ‘surface slicks’ in Hawai’i. These ocean features create a superhighway of nursery habitat for more than 100 species of commercially and ecologically important fishes, such as mahi-mahi, jacks, and billfish. Their findings were published today in the journal Scientific Reports.
(Massachusetts Institute of Technology) MIT geologists have produced a new timeline of Earth’s Paleozoic climate changes. The record shows ancient temperature variations coinciding with shifts in planet’s biodiversity.
Paleontologists use ancient marine faunas to test long-term changes in our warming oceans.
Oceanographers fully reconciled climate and carbon cycle trends of the past 50 million years — solving a controversy debated in the scientific literature for decades.
