Lineated sheet flows form when molten lava flows out from underneath the edge of a solidified crust. The lineations are a result of the crust scraping against the surface of the moving molten lava.

Jumbled sheet flows form when the solidifying surface of the lava begins to fold under compression from the flow behind it.

Hackly sheet flows form when the solidifying surface of the fast moving lava experiences so much deformation that the solidified surface begins to break apart and piles up on itself. The edges are very rough and sharp.

Lobate flows form from low effusivity flows. (more..)

Pillow lavas (also called pillow basalts) result from the quenching - or very rapid cooling and crystallization - of the outer portion of a small extrusion of lava. Continued extrusion breaks through one pillow and forms a new adjacent pillow. Striations may occur from the lava being scraped by the rough edges at the point of fracture and extrusion.

Mitch Elend works to stitch images of the seafloor at Southern Hydrate Ridge together into a photo mosaic in real time. OOI scientists will use the final mosaic to plan the instrument layout for the cabled observatory component of the OOI. (photo by Allison Fundis)

The ROV ROPOS with the digital still camera and lights repositioned to optimize the vehicle for a down-looking still image survey. Images obtained during this survey will be stitched together to form a photomosaic which will give scientists on board a visual map of an extensive portion of Southern Hydrate Ridge.
