This image shows the claw and arm of Alvin, grasping a “wedge” of pillow basalt (see Figure 3) pulled from a fractured pillow. Here the claw is grasping the pillow interior end and the rind is at the far right of the sample. Image courtesy of NOAA, WHOI, the Alvin Group and the 2004 GOA Seamount Exploration Science Party
