PLATE 5 Example of a contact along one of the scalloped lava flow fronts that
are well-imaged in the DSL-120A sidescan data. Mosaic of images is from Camera
Tow#6, which traversed the contact several times. Contact is between relatively
flat lying sedimented lobate flows (southeast) and a younger lava flow front
(northwest) consisting of pillow tubes, bulbous pillows and pillow lavas. The front
is 1-2m high, several tens of meters wide and ~lOOm long. The seafloor behind
(west of) the front is relatively flat and consists of relatively unsedimented lobates
with collapse pits and an occasional sheet flow channel.

PLATE 6 (A) Discovery of a young vent community during the Galapagos Rift
2002 Expedition, dubbed "Rosebud." (B) Chimera fish swims over numerous large
clams and a small clump of mussels that line the cracks between the pillow lavas
at the new hydrothermal vent site.

PLATE 7 (A) The cephalopod equivalent to the Coelacanth Vampyroteuthis
infernalis, the vampire squid from hell. Captured at 850m depth above Sumisu
Seamount, Ogasawara Island Chain, by the Japan Marine Science and Technology
Center's ROV HyperDolphin. (B) The citrate octopus Stauroteuthis syrtensis is an
inhabitant of the narrow benthopelagic transition zone and was known only from
very rare net-captured specimens. Recent capture of a live specimen by Harbor
Branch Oceanographic Institution's Johnson Sea-Link submersible led to the dis-
covery of a remarkable evolutionary transition of suckers into light organs.

PLATE 8 Typical midwater biota: (A) Cunina peregrine, collected at 300m in the
Gulf of Maine. (B) Histioteuthis sp., called the cock-eyed squid. (C) Periphylla
periphylla, possibly the most abundant deep-sea scyphomedusa is found in all
oceans, generally below 900m. (D) Nanomia care is a common bioluminescent
iphonophore in the Gulf of Maine. (E) Meganyctiphanes norvegica (Crustacea:
Euphausiacea, Northern krill), is critical component of the midwater food web. (F)
Tomopteris sp., an inhabitant of the midwater, this polychaete worm was collected
from 1,200m depth off the Northwest Coast of Africa. The field of view for all
figures is no more than 20 centimeters.
