Lamont scientists utilize a variety of observational and computational techniques to image and model the deep interior of the Earth, from crust to core.
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.
