SubC - Drop/Tow Camera

Wood Hole Oceanographic used SubC cameras to film Lava Tubes in Hawaii.  Three types of lava flows are common on the seafloor: pillow lava, lobate lava, and sheet lava. Scientists believe the main difference between the shapes of submarine lava results from how fast the lava erupts from deep-sea fissures and how steep the seafloor is that the lava travels over.
