GeoB163120-2 is a gravity core taken from a sediment drift deposit in the Campeche Mound Province, an area with multiple cold-water coral mounds. Taken from the nearby seafloor, it provides a perfect record to compare the common sedimentary system surrounding the mounds (off-mound, background sedimentation) with cores taken from the cold-water coral mounds themselves. Here, we provide sediment dry bulk density measurements from sediment samples performed with Pycnometer following ODP Standards.
