Glacial Assessment: Past, Present and Future: Acquisition of Essential Research Instrumentation
Entry ID: vanderveen_OPP0321053


Summary
Abstract: The NSF OPP award # 0321053 supported a Major Research Instrumentation (MRI)
purchase of equipment for Ohio State University's Glacial Assessment Program
(GAP). The program has three major thrusts: 1) documenting ongoing and recent
glacier change primarily using geophysical methods including remote sensing; 2)
assessing the recent changes from a long-term perspective provided by
high-resolution ice core-derived climate histories; and 3) projecting future
glacier changes by improving modeling capability, and hence, predicting future
climate forcing in terms of snowfall and ablation.

Acquisition of these instruments contributes to the Glacial Assessment
Program's ability to investigate glacier changes in the past, present and
future by enhancing OSU's technical capability to make critical observations
and analyses. More specifically, the spectroradiometer allows crucial field
observations of the spectral signature of periglacial landscapes, in order to
serve as validation for trimline mapping using multispectral satellite imagery.
The gravity meter is essential to make a more quantitative assessment of the
mass balances of Greenland, Antarctica and smaller glaciers and ice caps that
strongly control present and future sea level fluctuations. The mass
spectrometer and ion chromatographs provide critical augmentation to OSU's
capability to reconstruct past climate variability from ice cores recovered
from glaciers and ice caps from the equator to the poles and thereby
disentangle the various mechanisms forcing regional climates in the past.

Finally, computer clusters allow better prediction of future climate change via
the development of higher resolution simulations of regional climate.

Description: Research at the Center focuses on the role of cold regions in the global
climate system, with major research themes focused on:

* climatic reconstruction of glacial and post-glacial times;
* polar ice-sheets: dynamics, history and ice-atmosphere interactions;
* high-latitude landform evolution, soils and hydrology;
* geologic evolution of Antarctica;
* and the history of polar exploration.

Scientists at the Byrd Center are reconstructing past climate by studying
chemical records preserved in ice cores collected from glaciers in Greenland,
China, Peru and Antarctica. Fossils provide important evidence for much older
changes in climate and plant fossils collected in the Transantarctic Mountains
indicate that parts of the southern continent were once forested. Environmental
studies include programs in Alaska and Russia which are concerned with
hydrologic and geochemical cycles in permafrost terrains and interactions with
the biosphere. Modern processes such as the motion of the great ice sheets and
the circulation of storm systems around Antarctica are being studied with
sophisticated computer models and with satellite-borne sensors capable of
imaging the surface through cloud cover and during the long polar night.

The Center has an archival program which is a collaborative effort of the
Center and The Ohio State University Libraries/Archives.
