Collection

 |
| ALVIN taking ‘precision’ cores at 4,000 meters. |
The samples that we archive were collected on more than 425 separate oceanographic expeditions. The material in the collection was extracted from the seabed utilizing a wide variety of sampling hardware. Many specialized coring systems, dredges, grabs and articulating manipulators have been employed over the years to recover undisturbed samples of the seafloor. You'll find equipment configurations in use today here [look at hardware].
While the vast majority of the collection qualifies as ‘blue water’ (from deep ocean environments), we also keep cores from lakes in Africa, as well as North and South America.
