In a First, Scientists Successfully Forecast Undersea Eruption

August 09, 2011

Researchers returning from a cruise some 250 miles off the coast of Oregon have reported seeing a volcanic eruption on the seafloor that they accurately forecast five years ago—the first successful prediction of an undersea eruption. The event took place at Axial Seamount, one of the most active and intensely studied undersea peaks in the world.
New Google Ocean Maps Dive Down Deep

June 08, 2011

Starting today, armchair explorers will be able to view parts of the deep ocean floors in far greater detail than ever before, thanks to a new synthesis of seafloor topography released through Google Earth. Developed by oceanographers at Columbia University’s Lamont-Doherty Earth Observatory from scientific data collected on research cruises, the new feature tightens resolution in covered areas from the former 1-kilometer grids to just 100 meters.
No Longer Anchored, Antarctic Ice Stream Surges to Sea

June 21, 2010

Satellite tracking has shown that the Pine Island Glacier, one of Antarctica's largest ice streams, is accelerating and thus contributing a growing share of the melt water raising sea levels worldwide. A team of scientists visiting the region last year discovered one reason for the speed-up...
Scientists Locate Apparent Hydrothermal Vents off Antarctica

March 03, 2010

Scientists at Columbia’s Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn more about seafloor formation and the bizarre life forms drawn to these extreme environments.
Deep Magmatic Plumbing of Mid-Ocean Ridges Revealed

August 30, 2005

Some of the highest quality images ever taken of the Earth's lower crust reveal that the upper and lower crust form in two distinctly different ways. A team led by researchers from Columbia University's Lamont-Doherty Earth Observatory will publish the results of their work in the August 25 issue of the journal Nature.
Study Offers Alternative View on How Faults Form in the Ocean's Depths

April 11, 2005

Scientists have long held the belief that the fracturing of the Earth's brittle outer shell into faults along the deep ocean's mountainous landscape occurs only during long periods when no magma has intruded. Challenging this predominant theory, findings from a completed study show how differences in mid-ocean ridge magma-induced activity produce distinctly different types of ocean floor faulting.
New Observations on Shape of Ocean Mountain Ranges Turn an Old Idea Upside Down

June 18, 2004

What causes the peaks and valleys of the world’s great mountains? For continental ranges like the Appalachians or the Northwest’s Cascades, the geological picture is clearer. Continents crash or volcanoes erupt, then glaciers erode away. Yet scientists are still puzzling out what makes the highs high and the lows low for the planet’s largest mountain chain, the 55,000-mile-long Mid-Ocean Ridge.
