CEPS Earth Research

Terrestrial research at CEPS concentrates on the study of geophysical processes on the Earth's surface. These research projects are focused on surface dynamics in arid regions and comparative planetology of volcanic and tectonic landforms. The goals are to better understand processes such as volcanism, flooding, cratering, tectonics, and sand movement, that shape the surface of the Earth as we see it. Researchers at CEPS use field work and remote sensing techniques to investigate geomorphology and environmental changes on the Earth's surface.

Satellite remote sensing is a widely used method for CEPS scientists studying the surface of the Earth on a larger scale. CEPS houses a large archive of satellite data covering arid areas throughout the world. Data from visible and infrared wavelength sensors are used to understand geomorphology at the Earth's surface and identify areas undergoing biophysical changes. Active microwave sensors are used for studying volcanic features and drainage patterns in arid areas. Airphotos are used in projects where highly detailed data are required. High-precision GPS allows for spacial data that is very accurate, as well as quick and easy to obtain. The ease of use and transportation compared to traditional surveying equipment makes GPS ideal for CEPS scientists conducting field work in isolated areas.

CEPS researchers perform scientific field work in a variety of sites in the U.S. and throughout the world. Several of these field sites are investigated as analogues for planetary features. Terrestrial features that can be observed on other bodies in the solar sytem, such as sand dunes, landslides, and lava flows are surveyed to determine their history, and their appearence using various remote sensing techniques. Once the field sites on Earth are understood, they can be used to assist the interpretation of imagery and remote sensing data from planetary missions.

Terrestrial research at CEPS not only provides analogues for planetary features, but also provides a better understanding of environmental issues and geological hazards for those living on the Earth. Forest cover and land use studies provide maps of the changing surface. Sand movement and paleoflood studies help us to understand the changing climate of the Earth, and the risks to those living near sources of water. Studies of landslides and volcanic features are being used to better understand the hazards facing people that live nearby. CEPS research allows for better management and settlement of the increasingly populated surface of the Earth.
