Mark Kurz, of Woods Hole Oceanographic Institution, is a scientific collaborator for the short, 3-day mapping and sampling program we conducted off Fernandina Island. Here, Mark shows off one of the “toothpaste squeeze-out” samples that we dredged from the NW Rift zone of Fernandina. One of the interesting things about this rock is that it has many olivine crystals in it, while the lava samples on the island have very few olivine crystals. Mark, Mike Perfit, and Dennis Geist of the University of Idaho will be studying the geochemistry of the lava samples we recovered from the submarine rift zones of Fernandina.
