style="font-family:"Times New

subduction-zone related processes,
including major hazards such as great subduction earthquakes,
tsunamis, and
island volcanic eruptions, require the use of ocean bottom
seismographs (OBS)
for accurate imaging and detailed earthquake localization.
Passive margins like
the U.S. Atlantic, the North Slope of Alaska, and the Gulf of
Mexico, host
major oil, gas, and hydrate reservoirs and are prone to
submarine slope
failures and potentially landslide-generated tsunamis.
Shear-wave measurements,
which can only be recorded directly by on-bottom instruments,
provide valuable in
situ constraints on mechanical properties of marine sediments,
enabling us, for
example, to model forearc deformation and tsunami generation
during large
subduction earthquakes, assess the potential for submarine slope
failures, and
measure natural gas hydrate concentrations.<b>
</b>The advent of passive seismological techniques such as beam
forming,
seafloor compliance, and ambient noise imaging provide new tools
to analyze
data and learn new information about the seafloor and the
hazards it contains.
The USGS Woods Hole Science Center (WHSC), located within the
campus of the
Woods Hole Oceanographic Institution (WHOI), owns many of the
short-period OBS
in the academic fleet, and two intermediate-period seismographs,
and has access
to additional intermediate-period seismographs. It maintains a
close working
and technical relationship with the National OBS facility
(OBSIC) located at
WHOI. The USGS is also building jointly with WHOI a new fleet of
lightweight,
state-of-the-art OBS for rapid-response capability in response
to earthquakes
and volcanic events. Data from these short-term rapid-response
deployments will
also be available for analysis. In the immediate term, this
Mendenhall
post-doctoral position provides an opportunity to conduct
independent
innovative research on two existing passive seismology data sets
collected by
the OBS and to participate in the collection of new data sets.</span></p>
