|Dr. Hans-Peter Marshall,
Nominated by Dr. Martin Schneebeli (Swiss Federal Research Institute WSL), with supporting letters from Dr. John Bradford, Dr. Kelly Elder, and Dr. Matthew SturmDear AGU Cryosphere Focus Executive Committee,
I am writing to nominate Dr. Hans-Peter Marshall for the 2010 Cryosphere Young Investigator
Award. Dr. Marshall is currently Assistant Professor at Boise State University. His research
covers in my view an extra ordinate depth and breadth. His contributions are in the area of
– the development of innovative methods to measure and quantify the properties of
snowpacks, especially using radar, but also other modern tools, as micro-penetrometry
and near-infrared photography (publications 11, 13 and 15 in the biographical sketch)
– the development of new algorithms to make the complex data to become useful for
scientific interpretation (publications 9 and 14)
– application of these techniques in hydrology (e.g. in the CLPX10, publication 10), in
biology (Ptarmigan browsing and snowpack, publication 16), in snow avalanche
formation (publications 13, 12).
The development of such techniques is very important to advance science in the cryosphere. In
my view, HP Marshall is a young scientist which pushes new technologies, which is absolutely
necessary to broaden our understanding of the cryosphere on the ground and from space. HP
Marshall makes key contributions in this field, as is visible from his publications and from his
HP Marshall is a very active member of AGU, e.g. he is one of the representatives for the
Cryosphere Section of the AGU Fall meeting.
We also initiated the “Snow Characterization Workshops”. The first workshop was held in 2008
in Silverton, CO, USA, the second 2009 in Manali, India. These workshops offer the opportunity
to learn modern techniques of snow characterization for young scientists. We plan the next workshop to be held in Boise in March 2011. HP Marshall was instrumental to the idea and
These are just two examples for his unselfish help, in addition to his scientific achievements. I
suggest that HP Marshall is very well qualified for the Cryosphere Young Investigator Award.
