Volcano
Events Imagery - includes multichannel color composite
imagery showing ash
clouds (VSH), hotspots from lava flow (VIR) or both (VOL). We
also create grayscale "split-window" images which
use a channel differencing technique that enhances the appearance
of ash clouds in imagery (DIF). This technique is often useful
for distinguishing ash clouds from water vapor clouds.

Volcano - LIVE from the Axial Caldera
|
Bathymetric
map of the summit of Axial volcano, showing the caldera, the
1998 lava flow, and the locations of the components of the NeMO
Net 2002 system. The NeMO Net surface buoy is anchored at the
black dot and its mooring keeps it within the black watch-circle.
The Bottom Pressure Recorder (BPR) and two Remote Access Samplers
(RAS) are located on the seafloor at the blue dots. The blue
circles show the maximum range of the directional (for the RAS)
and omni-directional (for the BPR) acoustic modems. The new
omni-directional modem clearly has much greater range and therefore
gives the monitoring system much greater flexibility.
NEMO
Explorer - This
web site will take you a mile down beneath the ocean surface
to explore Axial Seamount, an active submarine volcano just
off the Oregon coast. Using virtual reality, we can put you
in a 3-D model of the seafloor and let you view hydrothermal
vents and fresh lava flows as if you were really there. At each
of the virtual sites below there is an animated tour and links
to video clips taken by a remotely operated vehicle (ROV).

NOAA's
Ocean Explorer web site - public access to current
information on a series of NOAA scientific and educational explorations
and activities in the marine environment. The site provides
a platform to follow explorations in near real-time, learn about
exploration technologies, observe remote marine flora and fauna
in the colorful multimedia gallery, read about NOAA’s
200-year history of ocean exploration, and discover additional
NOAA resources in a virtual library.
