Nolan, M.

We compared 7 years of local automated weather station (AWS) data to NCEP/NCAR reanalysis data to characterize the modern environment of Lake El'gygytgyn, in Chukotka Russia. We then used this comparison to estimate the air temperatures required to initiate and maintain multi-year lake-ice covers to aid in paleoclimate reconstructions of the 3.6 M years sediment record recovered from there. We present and describe data from our AWS from 2002–2008, which recorded air temperatures, relative humidity, precipitation, barometric pressure, and wind speed/direction, as well as subsurface soil moisture and temperature. Measured mean annual air temperature (MAAT) over this period was −10.4 °C with a slight warming trend...
Introduction Improving vehicle trafficability planning is a major defense mission, and we believe that this research has made significant improvements towards this end. We are striving to develop new space-borne Synthetic Aperture Radar (SAR) techniques to measure temporal changes in soil moisture, soil freeze/thaw state, and snowmelt, utilizing both amplitude and phase signal information. Such knowledge is of great use to a variety of end-users. Military planners need to predict the bearing strength of the underlying soil and thus the number and weight of vehicles able to travel across it. Global climate modelers need to know the surface greenhouse gas and latent heat flux. The common variables in these applications...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
