CAPECircum-Arctic Paleoenvironments
The role and aims of CAPE Prediction of future environmental change is one of the
greatest challenges to humankind, a challenge that must be met by the scientific
community. Although the issue of environmental change is global in nature, the study of
particularly sensitive areas may provide insights into changes of the Earth's environment
as a whole. Covering only a modest fraction of the planet, the Arctic includes many of the
most sensitive elements of the planetary system likely to change in the coming decades to
centuries. These changes within the Arctic may, via strong feedbacks, lead to large
impacts outside the Arctic region.
To better understand the role of the Arctic in the global climate system necessitates a
circum-Arctic approach. CAPE (Circum-Arctic PaleoEnvironments), an IGBP-PAGES
organization, provides the vehicle through which regionally focused national and
international Arctic paleo-programs can be linked. CAPE has circum-Arctic syntheses as its
primary mission, emphasizing integration of paleoenvironmental research on terrestrial
environments and the adjacent continental shelf covering the last 250,000 years of Earth
history. In addition to facilitating hemispheric syntheses, CAPE serves as a bridge
between the paleoenvironmental and modeling communities.
CAPE's focus on the Holocene The first task of CAPE is to compile environmental
changes in the Arctic during the Holocene at 1 ka intervals. To this end 12 regional
working groups covering specific sections of the Arctic, are being established. The goal
is to compile paleoenvironmental records for each section and to evaluate these records to
produce regional paleoenvironmental reconstructions. A final exercise will compare the
data synthesis results to GCM model output.
Strategy A wide range of terrestrial and marine proxies exist for the Holocene
as continuous times series. Our approach is to first characterize the Earth's surface at 1
ka time slices for the Holocene. On land this will be primarily based on paleovegetation
data (pollen and macrofossils) interpreted in terms of a limited number of vegetation
types. Additional surface characteristics will include the distribution of lakes and
glacier ice, while the key marine characteristics are sea ice distribution and water mass
type (e.g. Polar versus Atlantic/Pacific).
In April 1997 the compilers will meet in Lammi, Finland to review and compile their
results. The compilers will bring all primary site data used in their synthesis to resolve
inconsistencies between regional interpretations, and for inclusion in the PAGES data
archive. Once any problems are resolved, the group will develop a circum-Arctic synthesis.

GAGE working group
The GAGE work group of the INQUA Commission on Glaciation is preparing a proposal for
the Landsat 7 archive program. We have been asked to submit glaciers from around the world
(except the U.S.A. and Antarctica) for consideration in the archive. A preliminary
proposal is now available at: www.emporia. edu/S/www/earthsci/gage/glacier7.html All
Quaternary scientists are invited to comment and suggest additional glaciers to include
with the proposal. The complete proposal will be delivered to NASA in Jan. '97. Contact:

Research Grants
for Isotopic Analyses
Geochron Laboratories, a division of Krueger Enterprises, Inc., annually awards
research grants to graduate students requiring interesting or new applications of isotopic
analyses. The awards consist of analytical services to be performed free of charge to the
winner in each category. For the past several years awards have been offered in K-Ar
dating, C-14 dating, and stable isotope ratio analyses (SIRA), SIRA in dietary studies,
and SIRA of fluid inclusions in minerals. The awards are offered by Geochron Labs to
encourage the application of isotopic analytical techniques to solve original and
significant problems. The application deadline is May 1, 1997. Early application is
suggested. For Research Award Program Guidelines and official rules, call 617-876-3691;
fax: 661-0148 or write 711 Concord Ave., Cambridge, MA 02138.
DRI's Jonathan
Davis Scholarship
The Quaternary Sciences Center of the Desert Research Institute awarded the 1996
scholarship to David O. Wilkins, University of Utah; Ronald R. Currey is his advisor.
David's research is "Late Quaternary Paleoenvironments in the Trans-Pecos Closed
Basin, West Texas and South-Central New Mexico." Saxon Sharpe, University of Nevada,
was also awarded a stipend for "Late Quaternary Mollusks: Developing the
Paleohydrology Link."
This memorial scholarship was established by family and friends of Jonathan, a geologist
and geoarchaelogist. This annual $1000 (or more) scholarship supports the field research
of a graduate student working on the Quaternary geology of the Great Basin or surrounding
areas. The scholarship, administered by the Quaternary Sciences Center of the Desert
Research Institute, is open to graduate students enrolled in a M.S. or Ph.D. program at
any U.S. University.
Applications for 1997 should include: (1) a current resume or vita, (2) a two page
(single-spaced) description of the thesis/dissertation research which clearly documents
the geologic orientation and research significance, and (3) a letter of recommendation
from the thesis/ dissertation supervisor that emphasizes the student's research ability
and potential as a Quaternary scientist. Applications must be received by February 1,
1997, so
the scholarship can be used in the following summer. Send applications to:
Executive Director, Quaternary Sciences Center, Desert Research Institute, PO Box 60220,
Reno NV 89506. If you wish to help the endowment grow, contributions can be sent to the
above address. Checks should be made out to the Board of Regents-DRI. Please indicate that
the donation is for the Jonathan O. Davis Scholarship Fund.
