The research team ended up drilling a record-breaking hole of 1,268 meters into the Earth’s mantle. They also had a 71% recovery rate, recovering 886 meters of rock samples from the Atlantis Massif.

This cylindrical core sample, ... “Previously, we have been largely limited to mantle samples dredged from the sea floor,” he added. The core sample has a diameter of about 6.5cm.

This sample, which is more than six times longer than the previous core of mantle rock, has given us a glimpse into the composition of this mostly inaccessible layer of the Earth. You can read ...

A core sample taken from the seafloor of the Gulf of Mexico shows a 2-inch layer of oily material at the top. Scientists say this layer contains oil digested by marine life as well as some dead ...

Scientists regularly extract core samples—cylindrical samples of material from deep under the Earth’s surface—to examine the composition of different layers.

The research team analyzed more than 5,400 invertebrate microfossils — including sea urchins, clams, snails and crustaceans — from the offshore Santa Barbara sample. The sediment core ...

The core sample they recovered comprises more than 70% of the rock - 2,907 feet ... "Previously, we have been largely limited to mantle samples dredged from the seafloor," Lissenberg added.
