In summer 2008 we conducted the first multi-streamer Multi-Channel Seismic program of Lamont’s new national marine seismic facility, the R/V Langseth.

October 21, 2014Two-thirds of earth’s surface is covered in oceanic crust, but the deep plumbing that generates new crust remains poorly understood. New images from a chain of volcanoes beneath the Pacific Ocean show that magma may be erupting from a multi-layered magma chamber extending two miles or more beneath the seafloor, far deeper than originally thought.

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.

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.

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 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.

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.

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.

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.
