AGU Meeting Announcement: Research Support in Interior Greenland
Vision for Research Support in Interior Greenland
Meeting Thursday, 8
December (18:30-20:00) in ARCUS Community Meeting Room (Pacific Room
J, in the Marriot)
Recent investments by OPP
ARSL have recreated capability to support research high on the
Greenland ice sheet using overland traverses in addition to aircraft.
To date the Greenland Inland Traverse (GrIT) has been in
development, but has successfully completed two round trips from
Thule to Summit, delivering significant quantities of fuel to both
NEEM and Summit in the 2010 and 2011 seasons. Plans are being
developed to expand capacity and capability of GrIT. One motivating
factor for expanding GrIT is to facilitate the demobilization of NEEM
and redevelopment of Summit, but it is also exciting to point out
that an operational GrIT ushers in expanded opportunities to support
a range of research projects literally anywhere on the central
portion of the ice sheet.
The concept for
operational GrIT envisions a "split fleet" with one part
shuttling material from Thule through the marginal zone during a
brief springtime window each year, while the other part of the fleet
transports material from the inland side of the margin to wherever
it is needed. The inland part of the fleet should be able to operate
throughout summer, or maybe even longer.
The inland fleet will
need a logistical hub on the ice sheet, for maintenance and
over-wintering. The location of this hub may be permanent, or it
could move frequently, but it will not be at Summit. The hub
could be a base for summertime science projects, and possible year
round access to the hub is being considered.
The inland logistic hub
for GrIT is expected to also serve as the home base for flexible
"Mobile Camps" that will be available for deployment
where needed to support future science. Design of these camps is in
very early stages.
OPP and CPS are
seeking input from the community doing, or contemplating, research on
the Greenland ice sheet. Thoughts on possible locations for an
interior logistics hub are welcome. Comments on the types of support
and facilities that should be incorporated into Mobile Camps will be
particularly useful. Some questions we solicit responses to include:
How large would a
field team have to be for your science requirements?
Would you plan to
make measurements along a traverse route, or would your work be
focused on a certain region around a deployed Mobile Camp?
For survey types of
research, would you work only while vehicles/sleds were in transit,
or would you need frequent stops for a few hours or days?
If your research is
mainly stationary, would you need a camp for a few days/weeks, most
of a summer season, or multiple summers at a single location?
We expect that nearly
every investigator or research team will have different responses to
these types of questions. Therefore we hope that you can join us in
San Francisco to make sure your needs and views are known as the
discussion and planning move forward.
