On the left: The beach terraces that Jody, Beth, Bre and Jesse worked on profiling and excavating at Os’ma Bay. In this image from the beach you can see three of the four terraces that we measured. Marine terraces are tectonically uplifted beaches, as opposed to beach ridges, which form when the water level moves lower. One of the clues to this is that from the top of each step you could see that the area behind it was flat rather than a trough, like with the beach ridges. On the right: A picture from the top of southern Urup looking north toward the volcanoes that lie between us and the palynologists at Tokotan. If you look closely you can see the Gipanis in the middle lower left of the image, anchored off the coast. |
