The North Atlantic northern right whale, considered to be the most endangered large whale species, is headed for extinction unless human intervention improves survival, according to a new study by researchers at Woods Hole Oceanographic Institution and the University of Massachusetts.
Potential landslides on the outer continental shelf and slope along the Mid-Atlantic coast could trigger tsunamis that might have devastating effects on populated coastal areas; newly discovered cracks along the edge of the continental shelf could be an early warning sign that the seafloor is unstable in these areas (Geology, 5-00).
A team of scientists investigating whether possible cracks along the outer continental shelf off the mid-Atlantic coast might lead to a tsunami-causing landslide has discovered that the entire area is charged with gas.
Scientists who fertilized a small patch of the Southern Ocean near Antarctica in 1999 to determine if the iron would stimulate growth of algae that consume carbon dioxide, a major greenhouse gas, say their results show that iron supply does control algal growth during the summer but that the long-term fate of the carbon remains unknown.
Scientists exploring a remote area of the central Indian Ocean seafloor two and one-half miles deep have found animals that look like fuzzy snowballs and chimney-like structures two stories tall spewing super-heated water full of toxic metals.
For nearly 25 years, scientists have wondered how giant red-tipped tube worms and other exotic marine life found at hydrothermal vents on the deep sea floor get from place to place and how long their larva survive in a cold, eternally dark place. Now a Woods Hole Oceanographic Institution Biologist and colleagues have helped answer those questions.
The "Rose Garden" - one of the most well-visited and lush communities of seafloor vent life - may have been paved over by a recent volcanic eruption. But scientists on a just-completed expedition near the Galapagos Islands have discovered a thriving new community of very young tubeworms, clams, and mussels, which they have called "Rosebud."
Thirty years after approximately 175,000 gallons of No. 2 fuel oil spilled from the barge FLORIDA in Buzzards Bay near West Falmouth, MA, residues of the oil can still be found in salt marsh sediments, according to a report to be released November 15 by scientists at the Woods Hole Oceanographic Institution and colleagues at the U.S. Coast Guard Academy.
Scientists have found new evidence indicating that during periods of rapid climate warming methane gas has been released periodically from the seafloor in intense eruptions. In a study published in the current issue of the journal Science, Kai-Uwe Hinrichs and colleagues Laura Hmelo and Sean Sylva of the Woods Hole Oceanographic Institution (WHOI) provide a direct link between methane reservoirs in coastal marine sediments and the global carbon cycle, an indicator of global warming and cooling.
New analysis of sediment samples from the southern Caribbean indicate that severe droughts occurred at the same time as the known collapse of the Mayan civilization.
