- MoMar Scene File
This new scene file of the MoMAR site highlights the recent work of Singh and others [2006] in documenting the presence of an axial magma chamber beneath the
Lucky Strike Hydrothermal
Field
underlying the center of the 37°N segment, Mid-Atlantic Ridge.
Three cross-axis and one
along-axis
multichannel seismic (MCS) profiles highlight magma chamber
presence, seismic layer 2A and
reflections
from the bounding faults of the axial valley. These 2-D profiles
are migrated at water
velocity, so the
overall size of the magma chamber at depth will diminish some, and
3-D processing has
shown that the
size of the magma body is further diminished with a 3-D approach
(pers. comm. Violiane
Combier). Both
color and greyscale versions of each 2-D profile highlighted in
Nature are included (just
check and
uncheck which profiles you want to view). A partially transparent,
40 m gridded
bathymetric map of the
Lucky Strike Segment is provided for overall context. This scene
file will soon be
updated to include
results from the 3D portion of this experiment. We would like to
thank Satish Singh,
Hélèn Carton and
Violaine Combier for providing their recent results; and IPGP Paris
for partial support of
this visualization
project. Stay tuned...[References]
