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...

Oct. 20 (UPI) -- The top commander of the U.S. Marine Corps in Europe and Africa, under investigation for his use of a racial slur, has been fired. Maj. Gen. Stephen Neary was relieved of his command on Monday, after a little over three months in the post.

Loud rap music was playing, including lyrics with racial epithets. Neary, who is White, asked junior troops how they would feel if he said the N-word, according to a Marine who was there, speaking to Stripes on the condition of anonymity. NBC, quoting unnamed military officials, also reported the probe was centered on allegations that Neary used th...

Sept. 3 (UPI) -- The Marine Corps this week stood up a dedicated group to upgrade its ability to prevent and counter cyberattacks -- and minimize disruptions and shortages. The Network Activity - National Capital Region in Quantico, Virginia is the second network-focused unit and will follow the model pioneered by the 1st Network Battalion out of Camp Pendleton in California, according to a Marine Corps press release.

"This will realign the workforce and all of its resources; I'm talking about people and money," said Col. Edward J. Debish, the commanding officer of Marine Corps Cyberspace Operations Group during an activation ceremony Wednesday. In total, the Marine Corp...
Paleontologists find giant lizard in stomach of a prehistoric marine carnivore

Paleontologists find giant lizard in stomach of a prehistoric marine carnivore

Science
Aug. 20 (UPI) -- Until now, scientists thought ichthyosaurs -- the large, dolphin-like marine reptiles that cruised the seas of the Mesozoic -- mostly ate cephalopods. "Many of the large ichthyosaurs have blunt teeth that look more suited for squid-eating than megapredation," researcher Ryosuke Motani, professor of paleobiology at the University of California, Davis, told UPI in an email. "That is why we thought they were squid eaters." Advertisement But recently, Motani and his research partners discovered the well-preserved remains of a lizard-like aquatic reptile called a thalattosaur inside the stomach of Middle Triassic ichthyosaur. The fossil, described Thursday in the journal iScience, represents the oldest record of megafaunal predation by a marine reptile. "We have to readjust ou...
