Patterns in the Landscape – Analyses of Cause and Effect

For two decades, USGS scientists with the Land Cover Trends team have used satellite data to study landscape change across the United States. Increasingly, research is focused on understanding why change occurs. Insights into the underlying causes of shifts in land use and land cover (LULC) will allow managers and stakeholders to make more informed...

GIS-based landscape analysis to identify sources of endocrine disrupting chemicals

A key component to assessing the contaminant exposure pathways in streams and rivers of the Chesapeake Bay is using GIS-based landscape analysis to identify sources of endocrine disrupting chemicals. Municipal and industrial wastewater treatment plant (WWTP) discharges are potentially major sources of EDCs to streams, and therefore understanding the de facto wastewater reuse (represented as...

The Pacific Coastal Fog Project

Coastal marine fog is an important meteorological phenomenon for California.  A cloud—either stratus or stratocumulus—is called “fog” when it is low or touching the ground. Marine fog forms as a result of complex interactions between ocean evaporation, aerosols, atmospheric pressure, vertical air layering, onshore-offshore temperature gradients, and coastal mountain topography. The marine...

Land Use and Climate Change Team

We are a research team focusing on understanding the rates, causes, and consequences of land change across a range of geographic and temporal scales. Our emphasis is on developing alternative future projections and quantifying the impact on environmental systems, in particular, the role of land-use change on ecosystem carbon dynamics.

We are interested in how land-use and climate...

Delineation of Vegetation Using Satellite Imagery, Clark County

In 2006, USGS, in cooperation with the Bureau of Land Management (BLM), began a 4-year study of the Red Rock Canyon National Conservation Area (NCA) to produce a land-cover data set from DigitalGlobe’s QuickBird high-resolution (2.4-meter) satellite imagery and field vegetation data. In 2010, the study was extended to include the Clark County portion of Mormon Mesa, and Coyote Springs and...

Energy development and the airspace

Today, the alternative energy and telecommunications industries are developing the airspace much the way metropolitan growth and mechanized agriculture develop the landscape. NOROCK scientists and partners are using both historical and traditional technologies in new and innovative ways to observe wildlife behaviors in response to these changing habitats.

Tracking the Bad Guys: Toxic Algal Blooms

Every few days, a fleet of satellites orbiting 700 kilometers above the Earth scans the continental United States to help keep Americans safe. But these eyes in the sky aren’t seeking terrorists or enemy combatants: they scrutinize lakes to locate problems of the microbial variety, namely cyanobacteria.
