Traditional soil survey products deliver information about soil properties without taking into account current land use or management systems. Soil surveys vary in the scale of information they provide on spatial, taxonomic and property–specific scales. The order (spatial scale) and purpose of a given soil survey impacts the design of soil mapping units.

Biological productivity in many oligotrophic ocean regions is controlled by the availability of the nutrients iron and phosphorus. In these oligotrophic regions, atmospheric aerosol deposition is a key source of these nutrients. Understanding composition of phosphorus and iron in aerosols is critical for determining the key factors controlling their solubility and ultimately their potential bioavailability to marine organisms.

Anthropogenic activities such as river modification and dam operation have altered the natural hydrologic regime resulting in degraded riverine and riparian ecosystems. These ecosystems are sensitive to variations in hydrological regime such as magnitude, frequency, duration and timing, which are main indicators of environmental changes due to anthropogenic activities.

What do the geospatial patterns on Earth's surface tell us about the dynamical processes that occur at the critical interface between the Earth and its atmosphere? How can we use landscape patterns to improve our predictions of Earth surface processes in relation to climate change?

Unmanned Aircraft Systems (UAS) have made dramatic technical advances in the past decade. Currently, their domestic use is tightly constrained by Federal Aviation Administration (FAA) regulations. Within the next few years, the FAA is expected to provide a regulatory framework allowing for a greatly expanded role for UAS in domestic airspace in a wide variety of applications, including remote sensing for land and natural resource monitoring.
