*MEETING ANNOUNCEMENT*

A Science Planning Workshop for research with the Rapid Access Ice Drill
(RAID) will be held on March 2-3, 2017, at Scripps Institution of
Oceanography in La Jolla. Based on participant feedback and support from
the NSF, we have re-scheduled the meeting for early March. We encourage you
to attend. Information about the workshop is provided below — please pass
this on to others you think will be interested.

*Science Planning Workshop for research with the Rapid Access Ice Drill*
March 2-3, 2017
Scripps Institution of Oceanography
La Jolla, California

*Conveners:*
Jeff Severinghaus, Scripps Institution of Oceanography
John Goodge, University of Minnesota Duluth

We invite you to participate in a science workshop to help shape future
interdisciplinary research with the Rapid Access Ice Drill (RAID). Goals
and initial planning for the workshop are outlined below. Please see the RAID
website <http://www.rapidaccessicedrill.org/ to register with an
expression of interest.

*Goals of the workshop*: RAID is in Antarctica! Now is a good time to
bring together the scientific community interested in using the RAID system
for deep glacial and subglacial sampling, and for the boreholes it will
create, including integrated ice drilling, ice and rock coring, borehole
logging, and geophysical data acquisition. This workshop will provide a
venue to bring scientists together to explore new science questions or
approaches; define science goals; seek synergies between different
disciplines for RAID; and develop a coherent community science plan for use
of this unique drilling system. The workshop will be a great opportunity to
bring together researchers with scientific interests in ice-sheet dynamics,
paleoclimate, borehole logging, the ice-sheet interface, exposure and
uplift histories, subglacial bedrock geology, subglacial sediments,
microbiology, heat flow, potential-field geophysics, seismology, geodetics,
and ice-penetrating radar.

*When*: Thursday and Friday, March 2-3, 2017. This will be a 2-day
meeting, convened from 0800-1800 each day. Participants are encouraged to
arrive in San Diego on March 1 and depart either the evening of the 3rd or
over the following weekend.

*Where*: Scripps Institution of Oceanography and University of California
San Diego in La Jolla.

*Who*: The workshop is open to all scientists interested in using or
contributing to the science enabled by RAID. Please pass this announcement
on to anyone who might be interested. Please help us reach young
investigators and under-represented groups by sharing this announcement and
suggesting to us the names of people we can contact.

*Cost*: There will be no meeting registration cost. Breakfast and lunch
meals will be provided. NSF is funding the workshop in order to provide
partial travel to some US participants for travel and accommodation.
Preference will be given to young and under-represented investigators.

*Responses*: Interested participants should complete an electronic reply
on the RAID website (www.rapidaccessicedrill.org/2016-science-workshop/) to
provide an expression of scientific interest so that we can plan for the
number of attendees and workshop agenda.

*What is RAID? *The Rapid Access Ice Drill is a mobile system capable of
rapidly drilling deep boreholes in the Antarctic ice sheets and retrieving
cores of deep ice, the glacial bed, and bedrock below. It will provide a
critical first look at the interface between major ice caps and subglacial
features over a wide area. RAID is designed to enable interdisciplinary
research, including direct observation at the base of the modern ice
sheets, access to polar paleoclimate records in ice >1 Ma, and recovery of
billion-year rock cores from ice-covered East Antarctica, among many other
multidisciplinary topics of interest that RAID can address. Because of its
traversing capability, RAID can quickly make deep boreholes that will
remain open for future down-hole observation. The RAID system was designed
and optimized for drilling and coring in dry, frozen-bed conditions as will
be encountered in the thick East Antarctic ice sheet. The initial operating
region for RAID will be in the vicinity of and radiating from South Pole
station toward the ice sheet interior.

*What can RAID do? *With an ice-cutting rate of up to 3 m/min, RAID is
capable of making rapid boreholes in thick ice followed by coring in ice,
the glacial bed, and subglacial bedrock. Example drilling targets include:

- ice borehole — laser/optical logging to determine age of ice;
temperature profile; acoustic log of deformation
- short ice cores — reconnaissance sampling of ‘old’ ice (>1 Ma)
- glacial bed — ice flow processes, basal material, microorganisms
- short rock cores — samples for age dating, composition, surface
exposure ages, crustal and uplift history, validation of potential-field
geophysical characteristics
- rock borehole instrumentation — heat flow, seismology, geodetics

*RAID status: *RAID is currently on the ice undergoing field trials.
Recent developments include:

- design completed in late 2013
- construction and outfitting of modules began in Utah in mid-2014
- construction of cryogenic ice-drilling facility in Utah in early 2015
- North American test of key components and drilling rates completed in
March 2015
- fabrication and construction of all major sub-systems in Utah in 2015
- completion of integration and validation in October 2015
- commissioned in early November 2015
- shipment to Antarctica complete in January 2016
- Antarctic Field Trials currently underway near McMurdo Station

Please plan to attend the RAID science workshop this spring!

We look forward to seeing a wide range of participants.
