Columbia University’s world-renowned Lamont-Doherty Earth Observatory has received a gift of marine seismic technology equipment from a leading geoscience firm, CGG Inc. The donation has enabled Lamont to advance its world-class ocean research capacities and opens the door to new areas of sub-seafloor exploration, including an expanded understanding of the undersea dynamics related to earthquakes and tsunamis as well as climate science and impacts of sea level change.

The New Jersey shoreline that sea birds wandered during the last ice age is about 90 miles east of today’s beaches, tens of meters beneath the sea floor. As the ice melted, sea level gradually rose and flooded the coastal terrain, and sedimentation carried out its relentless burial of things past.
This summer, a group of scientists spent several weeks aboard the R/V Marcus G. Langseth looking into that past. Using sound waves, they collected data that will be used to build 3D images of the sediment beneath the ocean floor. They hope to be able to peel back layers of the 3D images to see how coastal landscapes responded to rising sea levels and hurricanes through history.
