4950 thumbnail picture
Classic pillow lava
2011 July 15
4951 thumbnail picture
Classic pillow lava with red holothurian.
2011 July 15
4952 thumbnail picture
Pillow lavas and murky water. Perhaps hydrothermal activity is close by.
2011 July 15
4953 thumbnail picture
Ropy pahoehoe lava on seafloor preserves direction of flow of lava. Perhaps . arcuate appearing area in lower left is indicative of eddy in fast moving sheet flow.
2011 July 15
4954 thumbnail picture
Lava structure on sea floor.
2011 July 15
4955 thumbnail picture
An archway formed by lava pillars supporting a remnant of intact lobate lava flow crust within a large collapsed lava lake. Individual ledges on the pillar form as "bathtub rings" as the lava freezes to the side of the pillar during the draining of the lava lake.

2011 July 15
4963 thumbnail picture
Baked appearance to rock surface
2011 July 15
4964 thumbnail picture
Crevasse cutting through pillow lavas. Murky water indicates nearby hydrothermal activity.
2011 July 15
4965 thumbnail picture
Pillow lavas with hundreds of dead mussel shells littering spaces between pillows. A hydrothermal vent community was here in the past but the activity has apparently ceased in this area leading to the death of the associated chemosynthetic community.
2011 July 15
4966 thumbnail picture
Smooth baked appearance with pink alteration along cracks.
2011 July 15
4967 thumbnail picture
Baked appearance to rock surface with indications of hydrothermal alteration.
2011 July 15
4968 thumbnail picture
A fresh lava flow of black pillow lavas overlying older pillow lavas having sediment cover. Creation in process.
2011 July 15
4969 thumbnail picture
Baked appearing rock with circular shatter patterns and some indication of hydrothermal alteration.
2011 July 15
4970 thumbnail picture
A smooth pahoehoe lava flow with a pinkish red holothurian.
2011 July 20
4971 thumbnail picture
Yellow and brown hydrothermal alteration
2011 July 21
4972 thumbnail picture
A collapsed pillow lava with the lava frozen in place after flowing out.
2011 July 21
4973 thumbnail picture
Yellow areas along crack possibly iron oxide staining but without sampling to verify its composition, it could also be of biological origin
2011 July 24
4974 thumbnail picture
Yellow areas along crack possibly iron oxide staining but without sampling to verify its composition, it could also be of biological origin. The black rim surrounding the yellow area coupled with a hint of white and gray lends credence to the possibility of its being of biological origin.
2011 July 24
4975 thumbnail picture
Patterns of black staining on a sand and mud bottom area. Is this material of geological or biological origin?
2011 July 24
4976 thumbnail picture
A burrow in the sand with a white leg (brittle star?) poking out.
2011 July 24
4977 thumbnail picture
White sediment material dug out of a burrow and deposited on the sea floor surface.
2011 July 24
4978 thumbnail picture
A large dead mussel shell indicating hydrothermal venting in this area in the past.
2011 July 24
4979 thumbnail picture
Black patterns on a sediment substrate. As with image expl6429, is this material of geological or biological origin?
2011 July 24
4980 thumbnail picture
A clam shell and mussel shells in association with pillow lavas.
2011 July 16
4981 thumbnail picture
Murky water, a few red shrimp seen in the foreground, and dead mussel shells to the left. Is a vent nearby?
2011 July 16
4982 thumbnail picture
Two more shrimp on a pillow lava. Maybe a vent is nearby.
2011 July 16
4983 thumbnail picture
Murky water, a deep sea fish, but little life apparent on rock surface of lava flow.
2011 July 16
4984 thumbnail picture
A recent pillow lava flow with biological material resting between the pillows, indicating where low-temperature hydrothermal fluid has been leaking out of the crust.
2011 July 16
4985 thumbnail picture
A recent pillow lava flow with biological material resting between the pillows, indicating where low-temperature hydrothermal fluid has been leaking out of the crust.
2011 July 16
4986 thumbnail picture
A recent pillow lava flow with biological material resting between the pillows, indicating where low-temperature hydrothermal fluid has been leaking out of the crust.
2011 July 16
4987 thumbnail picture
A recent pillow lava flow with biological material resting between the pillows, indicating where low-temperature hydrothermal fluid has been leaking out of the crust.
2011 July 16
4988 thumbnail picture
Angular boulders of volcanic rock. A lone white squat lobster shows up in stark contrast to the dark rocks. Some pinkish bacterial material provides evidence of warm mineral laden waters seeping from the earth in this area.
2011 July 16
4989 thumbnail picture
Sheet flows and pillow lavas with pink biological material indicating where low- temperature hydrothermal fluid is leaking out of the crust. Cloudy water to the right is indicative of these hydrothermal fluids.
2011 July 16
4990 thumbnail picture
Aspect of image makes it difficult to say whether this is a vertical spire or a horizontal spur of volcanic rock jutting into a crevice. The texture of the rock surface indicates that it is lying horizontally and that it is composed of frozen lava.
2011 July 16
4991 thumbnail picture
Relatively new pillow lavas which have yet to accumulate much sediment. Pinkish color is caused by biological material obtaining nutrients from low-temperature hydrothermal fluids.
2011 July 16
4992 thumbnail picture
Appear to be looking down into a crevice. Are pink globules rising gaseous material or falling particulate matter? Three brachyuran vent crabs, possibly Bythograea thermydron, can be seen below.
2011 July 16
4993 thumbnail picture
A recent lava flow showing white microbial staining on the broken basaltic rocks , caused by discharge of warm hydrothermal fluids through the seafloor.
2011 July 16
4994 thumbnail picture
An area of angular boulders with white coating which is probably of biological origin. Two brachyuran crabs, possibly Bythograea thermydron, can be seen in lower left of image.
2011 July 16
4995 thumbnail picture
Two brachyuran crabs are seen on a volcanic rock column. Intense marine snow is falling in this area - possibly from surface biological material or possibly the snowflakes are minerals precipitating from nearby hydrothermal vent activity .

4996 thumbnail picture
A large fissure in the Galapagos rift area flanked by pillow lavas on each side.
2011 July 16
