The "Lead Scientist" for this CD project and is responsible for management,
coordination, and communication between all PIs and Nepali counterparts.
He has worked in the Himalaya since 1980 and in Nepal for the past 3 years.
He is involved in the field- and photo-based studies of landsliding, calibration
of bedrock incision rates by rivers, geodetic studies of bedrock deformation,
analysis of digital elevation models, and calibration of fluvial sediment
and water fluxes.
Responsible for developing and implementing the model for orographic
precipitation, snow distribution, climate variability across the study
area. She helped design the geometry of the new meteorological network,
and she assisted with installation of the field stations and with data
collection and interpretation of meteorological field data. She is
using her past experience with modeling of orographic precipitation
to customize a Himalayan model at a 2-km resolution. She is the primary
liaison with the NASA Tropical Rainfall Monitoring Mission which has provided
funding to her, Burbank, and Putkonen install a meteorological network
in the proposed study area. She has coordinated a major radiosonde experiment
(MOHPREX) during the 2001 monsoon season.
Responsible for the fission-track and [U-Th]/He thermochronometry.
She is developing chronologies for bedrock cooling using apatite fission-track
ages, track-length modeling, and newly developed U-Th-He dating techniques.
She has helped to plan and sample the vertical-relief profiles to constrain
the thermal model. Blythe operates and maintains the fission-track
lab at USC. She has been collaborating with researchers in the U-Th-He
lab at Caltech.
An Emmy award-winning, documentary film maker specializing in historical,
literary, and environmental topics. His films have been broadcast on Public
Television beginning in 1976, and have reached a widespread audience. Fisher
is in charge of writing and producing an hour-long film which will be aimed
at Nova-type audiences on PBS and will document this research project,
its scientific significance, and cultural impact.
Responsible for investigating the movement of water, sediment, and nutrients through the landscape, Dr Gabet has been largely focused on analyzing the hydrologic results from gauging the Marsyandi and tributaries over several monsoon season. He is also interested in how climate modulates sediment delivery and influences the shape of landforms.
Responsible for collecting, processing, and analyzing the samples used
for our radionuclide analyses. His measurements of 10Be and 26Al
concentrations from bedrock and river sediments helps define erosion rates
or minimum exposure ages depending on the sample application. He
recently completed work defining erosion rates, soil production functions,
bedrock erosion rates, and bedrock incision rates from six different field
sites using radionuclide analyses of bedrock and stream sediment samples.
He is using similar methodology for this project in his lab at Dartmouth.
He is fluent in Hindi and conversant in Nepali.
Specializes in the integration of structural geology, geochronology,
and metamorphic petrology to explore the processes of continental deformation.
Much of his research since 1983 has focused on the Himalayan orogen in
southern Tibet, India, and Nepal. He has directed a field geologic
program in the Annapurna Range for the past nine years. Hodges roles in
the Nepal CD project are: 1) to direct the 40Ar/39Ar dating studies outlined
in the proposal; 2) to extend our knowledge of the bedrock geology of the
Marsyandi tributary catchments; and 3) to help design thermal models that
will lead to a more robust interpretation of thermochronologic data in
terms of uplift rate. Hodges also brings experience with science education
through popular film making, having served as a Science Advisor for the
award-winning MacGillivray-Freeman IMAX film, Everest.
Responsible for estimating the amount and importance of glacial erosion.
He has also helped design and implement stream sampling strategies both
for particulate sediment load and for water discharge. He has extensive
experience in glacial dynamics, in both mountain and continental ice-sheet
environments, with past projects in Alaska, Greenland, Antarctica and the
Rockies. He has carried out theoretical and field studies of sub-glacial
erosion, and of chemical denudation in glaciated basins, and has published
one of the few data-based sub-glacial erosion laws.
Specializes in tectonic geomorphology and geodynamics. He has recently
completed a detailed calibration of growing folds in the Himalayan foothills,
sediment transport and erosion rates, geodynamic models of deformation
across the Himalayan orogen. He brings this expertise and skills with digital
topography and satellite imagery to bear on the problems of digital terrain
analysis, landsliding, bedrock incision, and reconstruction of average
rates of bedrock deformation.
Taking primary responsibility for the design, creation, installation,
and maintenance of the meteorological network. He has seven years of experience
in developing stand-alone meteorological stations for remote Arctic environments
and will apply a similar technology, adapted for deep snow conditions,
to the Nepal Himalaya. He is responsible for data collection and reduction,
maintenance of the meteorological network, and coordination with the Nepalese
Dept. of Hydrology and Meteorology.
