Title: The Least Bell's Vireo - A flagship species for riparian ecosystem conservation

The Least Bell's Vireo (Vireo bellii pusillus) is a songbird that is endangered in California:

• What type of research is the USGS doing to help understand the threats these and other birds face?
• How has our research during the last 30 years

Antarctica’s interior is circled by glacial ice flows that move outward from the frozen continent’s surface.

Imagery collected over Antarctica by satellites like Landsat is typically marked by highly reflective snow and ice, but isolated pockets of wind-swept glacial ice glow with a distinct blue.

This short video provides a quick demonstration of the Area Sample using the Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS). 

AppEEARS provides a simple and efficient way to subset, transform, and visualize geospatial data distributed from a variety of federal archives. The following topics are discussed in the video: how to submit an

Satellites have captured views of the numerous major fires burning in California.

An image acquired on November 9, 2018, from NASA’s MODIS sensor on the Terra satellite shows smoke pouring out of two major fires, the Camp Fire and the Woolsey Fire, which both ignited the day before.

In the north, the Camp Fire quickly became the deadliest wildfire in the

The USGS groundwater modeling program MODFLOW 6 uses three angles to help specify three components of hydraulic conductivity. This video provides a visual explanation of these three angles.
 

Another large iceberg recently broke off Pine Island Glacier, Antarctica. According to the U.S. National Ice Center, this iceberg, named B-46, has an area of 87 square miles. That’s slightly larger than the iceberg that previously separated from the glacier in September 2017.

B-46 broke away on October 29, 2018, just a month after a rift first appeared. The October

This 3D model of Pu‘u ‘Ō‘ō's crater was created from thermal images during an overflight of the cone. The deepest portion of the crater is about 320 meters (1050 feet) below the crater floor that existed prior to April 30.

In September 2011, the largest dam removal project in U.S. history began. 

Two dams built on the Elwha River in the early 1900s created two reservoirs in northwestern Washington. They also greatly reduced the amount of sediment flowing to the river’s delta and blocked salmon migration upstream into Olympic National Park.

USGS/EROS Physical Scientist Dean Gesch and USGS/EROS CoNED Applications Project Chief Jeff Danielson discuss the Coastal National Elevation Database (CoNED), its acquisition and its uses.
 

Drone footage of Whiskeytown National Recreation area in Northern California in October 2018, captured by drone pilot and USGS WERC ecologist Chase Freeman.

USGS WERC is using drone imagery to understand how the 2018 Carr Fire affected ecosystems and cultural resources. The study, a collaboration with the National Park Service (NPS), focuses on Whiskeytown National

Digital 3D reconstruction of lake bottom using 50 photo frames taken by the dive camera system. This example shows an arc since the sampling transect is a circle. This reconstruction allows us to gain more insight about the lake bottom since elevation has been added to the photographs.

USGS/EROS Physical Scientist Dean Gesch and USGS/EROS CoNED Applications Project Chief Jeff Danielson discuss different remote sensing methods they used to create topobathemetric elevation models of the Majuro Atoll.
 

Title: Post-Fire Debris-Flow Early Warning: The case for forecast-based warning systems

• Post-fire debris flows can initiate after only a few minutes of intense rain, and during the first storm following wildfire.
• Early warning systems must provide sufficient time to make informed decisions and take reasonable preventative action.
• If you're

Hurricane Michael made landfall in the Florida Panhandle on October 10, 2018.

Landsat 7 images captured before and after highlight the destructive path of the Category 4 storm.

Mexico Beach was all but demolished, with homes left in heaps by wind and storm surge. The green leaves that pop in the September image are stripped from trees by October, and the dull

The Central Valley of California is the predominant wintering area for waterfowl and shorebirds in the Pacific Flyway. Using remote sensing data, researchers and habitat managers can track and quantify the effects of drought on availability of wetlands and other flooded waterfowl habitats. Bird locations from GPS marked waterfowl may be used to evaluate performance of

October 16, 2018, marks the two-year anniversary of the Cottonwood Fire in western South Dakota. The fire consumed a large swath of grassland near the community of Wall and just north of Badlands National Park.

Thanks to low relative humidity, and high winds and temperatures, the fire spread quickly. It burned 41,360 acres by the time it was 100 percent contained

In southern Germany, autumn is synonymous with beer.

Around six million people visit the Bavarian city of Munich each year for Oktoberfest, a celebration of suds that coincides with the hops harvest.

The world’s largest continuous hops-growing region by area is Hallertau, just north of Munich. More than 80 percent of Germany’s hops come from this 42,000-acre

Hurricane Florence hit the Carolina coast on September 14, 2018, but it took much longer for the full impact to emerge.
Remotely-sensed images show the slow devastation that 13 trillion gallons of rain can bring as it moves back toward the sea.

The following series of lessons will cover how to use LiDAR data in the ArcGIS Pro environment. In this lesson, we will provide the user with an overview of how to load and view lidar files in the standard LAS format in both 2D and 3D.
 

High-water marks provide valuable data for understanding recent and historical flood events. The proper collection and recording of high-water mark data from perishable and preserved evidence informs flood assessments, research, and water resource management. This video provides guidance for skilled high-water mark identification, including marks left behind in natural and
