On March 16, NSF released a Dear Colleague Letter (DCL; NSF16-061; <a
class="moz-txt-link-freetext"
href="http://www.nsf.gov/pubs/2016/nsf16061/nsf16061.jsp"><a class="moz-txt-link-freetext" href="http://www.nsf.gov/pubs/2016/nsf16061/nsf16061.jsp">http://www.nsf.gov/pubs/2016/nsf16061/nsf16061.jsp</a></a>)
encouraging proposals for community-driven shoreline-crossing
seismological arrays along the Alaska subduction margin. The concept
follows directly from the success of the Cascadia Initiative (<a
class="moz-txt-link-freetext" href="http://cascadia.uoregon.edu/"><a class="moz-txt-link-freetext" href="http://cascadia.uoregon.edu/">http://cascadia.uoregon.edu/</a></a>)
community experiment, and is targeted toward subduction-related
problems of relevance to GeoPRISMS and EarthScope science plans. The
Alaska experiment would take advantage of the Alaska component of
the Earthscope Transportable Array currently being deployed, in a
region of great earthquakes and abundant volcanism. A workshop in
October, 2014 provided scientific rationale for such successors to
the Cascadia Amphibious Array, as outlined in a 2015 report (<a

href="https://www.iris.edu/hq/files/workshops/2014/10/amphibious_array_facility/docs/AAFW_Report_FINAL.pdf"><a class="moz-txt-link-freetext" href="https://www.iris.edu/hq/files/workshops/2014/10/amphibious_array_facility/docs/AAFW_Report_FINAL.pdf">https://www.iris.edu/hq/files/workshops/2014/10/amphibious_array_facility/docs/AAFW_Report_FINAL.pdf</a></a>).
Much of that report emphasized the seismogenic megathrust and
volatile cycling through the subduction factory as the two major
science targets that require broad, shoreline-crossing observations
in subduction zones. Both targets could be optimally addressed by
studies of the Alaska margin. The DCL specifically invites community
experiment proposals to be submitted to the July 15, 2016 GeoPRISMS
deadline.<br>
<br>
This webinar discusses some of the scientific opportunities for such
a shoreline-crossing deployment of seismometers across the Alaska
Margin, and opportunities for complementary magnetotelluric,
geodetic, and other geophysical observations. It focuses on
opportunities in the regions off the Alaska Peninsula and
south-central Alaska, where the on-land Transportable Array exists,
extending onshore and offshore. <br>
<br>
The presenters will also discuss ways community members could become
involved in a community proposal for such a deployment, along the
lines described by the DCL. A web page (<a

has been set up to engage community members and communicate
strategies, including a mechanism for qualified PI’s to volunteer to
join the PI team.<br>
<br>
This is an exciting opportunity to collect what should be one of the
seminal data sets from an active subduction zone.
