NeMO 2000 Video Clips

This page presents a selection of video highlights from the NeMO 2000 research expedition to the New Millennium Observatory (NeMO) at Axial Volcano, a seamount 300 miles offshore from the Oregon coast where a submarine volcanic eruption occurred in January 1998. To view a video, just click on one of the links below the "thumbnail" views. All of the video clips are in MPEG format and are available in two sizes. The small sized clips will load faster and may play more smoothly than the larger ones. To the right of each thumbnail is a brief description of the video clip. All the video clips on this page are played at 2 times normal speed.

Small/MPEG - 1.6 Mb Large/MPEG - 4.2 Mb	<-- ROPOS comes back up on deck after another full dive to the seafloor.	Small/MPEG - 0.8 Mb Large/MPEG - 2.0 Mb	<-- A view of the ROPOS console on the ship, with live video from the seafloor. This is where the ROPOS pilots control the vehicle on the bottom and the scientists direct the activities during the dive.
Small/MPEG - 0.8 Mb Large/MPEG - 2.2 Mb	<-- A view of the top of Castle vent, a pre-existing sulfide chimney just east of the 1998 lava flow. It is the only known high-temperature vent on Axial's south rift zone.	Small/MPEG - 0.8 Mb Large/MPEG - 2.3 Mb	<-- The top of Castle vent is mainly inactive, but there is an active anhydrite chimney at the base (276°C).
Small/MPEG - 0.3 Mb Large/MPEG - 1.0 Mb	<-- A huge exotic jellyfish encountered by ROPOS. This species is called "deepstaria enigmata" and is only known from ~10 other specimens from the NE Pacific.	Small/MPEG - 0.8 Mb Large/MPEG - 2.0 Mb	<-- The first of 3 clips of a fantastic encounter with a deepsea octopus that was clinging to a lava pillar (~4 m high) within the 1998 lava flow.
Small/MPEG - 1.1 Mb Large/MPEG - 3.0 Mb	<-- Second clip of ROPOS's octopus encounter. Octopus are one of the few large predators around hydrothermal vents.	Small/MPEG - 1.0 Mb Large/PMEG - 3.1 Mb	<-- Third clip of the octopus, giving us a good view of its underside.
Small/MPEG - 0.9 Mb Large/MPEG - 2.3 Mb	<-- View of a crack (~1.5 m wide) with 1998 lava welling up in the bottom. The lava erupted out of this crack nearby. This site shows how much the seafloor actually spread apart during the 1998 eruption.	Small/MPEG - 1.0 Mb Large/MPEG - 2.8 Mb	<-- At the south end of the 1998 eruption, mostly pillow lavas were erupted. But here we are inside a circular collapse pit on that flow where fluid lava drained out downslope during the eruption.
Small/MPEG - 0.3 Mb Large/MPEG - 0.8 Mb	<-- View of a scaleworm swimming up off the bottom. How do they do that?	Small/MPEG - 0.7 Mb Large/MPEG - 1.4 Mb	<-- Close up view showing a scaleworm (center) attacking a tubeworm! View from Nascent vent (the site on the 1998 lava flow where tubeworms first colonized on the new lava).
