Rocks at the bottom of the deep ocean provide marine food chains with vital nutrients

Rocks at the bottom of the deep ocean provide marine food chains with vital nutrients

Science
March 27 (UPI) -- Marine food chains are fueled by nutrients from decaying rocks located thousands of feet below the surface of the ocean. According to a new study, published this week in the journal PNAS, phytoplankton and marine algae, which form the bases of aquatic food webs, rely on nitrogen released from sediments on the floor of the deep ocean. Advertisement Previously, scientists have argued oxygen in the deep ocean prevents dissolved iron from escaping eroded seabed rocks. The latest findings suggest the opposite is true -- oxygen and organic matter in the deep ocean may actually aid the release of nitrogen from marine sediments. "Our findings reveal that the shallow surface of the deep seafloor provides an important source of iron -- a scarce micronutrient -- for the ocean," le...
Traces of primordial Earth’s magma ocean found hiding in Greenland’s rocks

Traces of primordial Earth’s magma ocean found hiding in Greenland’s rocks

Science
March 12 (UPI) -- Hidden in the ancient rocks of Greenland, scientists have found the geochemical signatures of Earth's early history, a time when the planet was one big ocean of magma. At some point during Earth's infancy, the molten ocean that covered the planet began to cool and crystalize, yielding Earth's earliest rocks and landforms. This process set the stage for Earth's tectonic evolution and the development of the planet's atmosphere. Advertisement Unfortunately, this process isn't well understood, as most all of the planet's rocks older than 4 billion years have been subsumed by Earth's interior and recycled. In a breakthrough discovery, however, the authors of a new study -- published Friday in the journal Science Advances -- claim to have found remnants of primordial Earth's m...
