Distribution of Migratory Landbirds around the Gulf of Mexico

Submitted by atripp on Thu, 06/17/2021 - 16:01

Over two-thirds of all land birds and over half of the migratory species in North America move long distances to areas in Mexico, Central and South America, and the Caribbean islands. For birds crossing the Gulf of Mexico, habitats along the northern coast provide the last possible stopover before autumn migrants make a nonstop flight.

Alaska Statewide Interferometric Synthetic Aperture Radar (InSAR) Elevation Data and Satellite Imagery Status

Submitted by atripp on Wed, 06/09/2021 - 14:09

The USGS 3D Elevation Program (3DEP) effort to acquire new statewide Alaska elevation data is complete. The overall goal of 3DEP is to complete acquisition of the first-ever national baseline of consistent high-resolution elevation data—both bare-earth and three-dimensional point clouds—collected in a timeframe of less than a decade.

Submitted by atripp on Fri, 05/21/2021 - 09:15

Caribou (Rangifer tarandus) are an iconic species of the north and an integral component of the natural ecosystem and socioeconomic wellbeing of local communities. Alaska is home to 32 different caribou herds which are identified by females returning to specific calving areas each spring to give birth.

Alaska Interferometric Synthetic Aperture Radar (InSAR) Elevation Data Status

Submitted by atripp on Thu, 04/02/2020 - 11:09

The USGS is coordinating a 3D Elevation Program (3DEP) effort with other Federal agency partners and the State of Alaska to acquire new statewide Alaska elevation data. Under its Geospatial Products and Services Contract (GPSC), the USGS is contracting with vendors to acquire 5-meter resolution elevation data using Interferometric Synthetic Aperture Radar (InSAR) sensors flown on aircraft.

The goal of the 3D Elevation Program (3DEP) is to complete acquisition of nationwide lidar (Interferometric Synthetic Aperture Radar (IfSAR) in Alaska) in 8 years to provide the first-ever national baseline of consistent high-resolution elevation data—both bare earth and 3D point clouds—collected in a timeframe of less than a decade.

Special Geologic Studies: Artisanal and Small-scale Mining of Conflict Minerals

Submitted by atripp on Thu, 04/02/2020 - 10:16

This project focuses on the illegal artisanal and small-scale mining (ASM) of small and low-grade mineral and gemstone deposits. Project scientists employ field mapping, geomorphological techniques, and remote sensing to map, monitor, and evaluate mineral deposits and ASM activities in conflict zones and during complex emergencies.
