Cores recoveredby the Japan-New Zealand-United States Dry Valley Drilling Project (DVDP) in
Antarctica are stored at the Florida State University's Antarctic ResearchFacility. More than 1100
m of DVDP drill core are stored at - 23øC,from which 3504 sampleshave been distributed to authorized investigatorsworldwide. All coresremain in excellentcondition,and further researchinterest
in them is invited.
INTRODUCTION
The purpose of this article is to introduce the
role of the Antarctic ResearchFacility at Florida
State University (FSU) within that of the Dry Valley Drilling Project (DVDP), and to providea summary accountof the status of the DVDP core collection curated at the facility, includingconditions
of storage,samplingmethods,and sampledistribution totals.
mestic repository for DVDP sedimentary materials.
In retrospect, this arrangement has proven
highly satisfactoryand representsa unique, cooperative effort in that the facility hasfunctionedas a
satellite sampledistributionand storagecenter for
DVDP materials under the direction and guidance
of the U.S. project coordinator,Lyle D. McGinnis
at Northern Illinois University.
The apparent anomalyof DVDP core storagebeing locatedin the state of Florida can be attributed
to the wealth of unused,refrigerated storagespace
availhblewithin the AntarcticMarine GeologyResearch Facility and Core Library at FSU. Acura-

DRY VALLEY DRILLING PROJECT
during May 1974, cores from sites 10-13 were received during March 1975, and coresfrom sites 14
and 15 during May 1976.
Essentially, the cores remain in excellent condition for further sampling, sincefrozen storage has
preserved the structural integrity of the icecemented sediments. In somelithologies,a loosely
consolidated,friable outer rind has developeddue
to the migration of ice out of the core by sublimation. In these cases,it is difficult to prevent some
sediment loss in handling and sampling due to
crumbling of the rind. Also, certain geochemical
studies of interstitial water may no longer be feasible due to moisture
loss.
SAMPLING
All sampling of DVDP core at the facility has
been carried out with the direct approval of the
U.S. coordinator of the project according to the
terms of the official DVDP samplingpolicy. At the
time of sampling,informationconcerningthe hole
and box number, sample interval, sampleweight,
proportion of core diameter sampled, and other
data, includingcommentsas may be necessitated,
for example,by problemsof interpretation,are recorded on a sample inventory form. Prepared in
triplicate, one copyof the form is forwardedto the
investigator receiving the samples,another is forwarded
Vol. 33
to the DVDP
office at Northern
Illinois
University, which maintainsa computerizedinventory of all DVDP samples,and the third copy remains in the DVDP
file at FSU.
Additional
inven-
tory controlis providedby the placementof sample
identification cards at the point of samplingwithin
each core box and by the recordingof sampleintervals and their locations,keyed to the investigator,
on individually printed sets of core box photos
which appear in Dry Valley Drilling Project bulletins 3, 5, and 7, prepared at Northern Illinois University.
All samplingis donewithin the 2øCstorageroom
and is effected by chiseling and handsawing
(rarely), dry sawing (no cutting fluid) by circular,
diamondblade utilizing a Felker Di-Met Model 41A
cut-off saw, or by diamondcore drilling usinga 38cm, floor model Clausingdrill press(Figure 2). The
latter method makes use of a precooleddrill bit using compressedair as a drilling 'fluid' and was developedby Don Elston of the U.S. GeologicalSurvey to obtain oriented sample 'plugs' for
paleomagneticstudiesof DVDP cores.
Voids in the core resulting from the removal of
samplesare filled with cut-to-fit piecesof Dow
Ethafoam rod in order to prevent shifting of core
segmentsduring box handling;thus the relative
positionsof the segmentsare preservedfor further
measurementof sampleintervals.
SAMPLE
DISTRIBUTION
Initial samplingand inspectionof the DVDP materials at FSU beganin August 1974with a contingent of sevenvisitinginvestigatorscoordinated
by
Peter N. Webb. A second DVDP core sampling
andinspectionsessionwas hostedby the facilityon
July 7, 8, and 9, 1975, involving 12 specialistsin
polar studies,and coordinatedjointly by Lyle D.
McGinnis and Mort D. Turner. For purposesof
both samplingand coreinspection,a total of 24 scientists have been receivedby the facility. An additional seven investigators have received samples
on the basis of letter requests as have many of
those who journeyed to the facility.
A total of 3504 samples has been distributed
from the DVDP collection at FSU over a 5-year
period. This total does not include samplesremoved from the coresprior to their arrival at the
facility, nor does it include the redistribution of
sampleportionsby investigatorsto whomsamples
were originally distributed. Figure 3 summarizes
the sampledistributiontotal accordingto the number of samplesreceived per hole by investigators
to whom the sampleswere assigned,and the number of samplesdistributed from eachhole.
The shipment of samplesto principal investigators has been by both frozen and unfrozenmeansof
transportation.Frozen samplesare packedin dry
ice within commercially available styrofoam containers and have been shipped by air to points as
far as Seattle without damageto or thawing of the
materials.
FUTURE
SAMPLING
Following publication of this volume, and the
correlation of the presented data with those of related projects underway, it is anticipated that
there will be a resurgence of interest in the availability of DVDP materials for further sampling.
Potential investigatorsrequiring samples,in order
to place a meaningfulrequest for them, are asked
to review carefully the available literature, particularly the DVDP bulletins prepared at Northern
Illinois University, in which appear the lithologic
