Core Repository
Check out cores, rocks and sediments taken from beneath the ocean floor.
The Lamont-Doherty Core Repository stores thousands of cores, rocks and sediments taken from beneath the ocean floor. Deep-sea sediments contain fossils of marine animals, volcanic glass, cosmic spherules, and other unusual materials unique to a marine environment. Deep-sea samples also hold a permanent record of magnetic history, revealing to scientists the ever- changing magnetic orientation of the poles. See how we find evidence of climate change, cosmic impacts and earthquakes in these sediments.
Good activity for ages 6 and up.
