The camera glances at the bottom of the boat above and then pans down to the lake bottom. The lake bottom is covered in tons of round gobies swimming around in and out of the cladophora. Again the camera pans up to show a diver and the dive camera completing a transect in the distance.
 

This short video provides a quick look at the Application for Extracting and Exploring Analysis Ready Samples (AppEEARS). AppEEARS provides a simple and efficient way to subset, transform, and visualize geospatial data distributed from a variety of federal archives. AppEEARS can be accessed by visiting https

This video provides an overview of the different indirect measurement methods used by the USGS, as well as a brief description of what you'll need to survey for each. 
 

Landsat 8 captured satellite views of California’s largest wildfire on record in the summer of 2018. The Mendocino Complex Fire in northern California is a combination of two fires: the Ranch Fire and the River Fire. 

Both fires started July 27, and hot, dry, windy conditions caused them to spread rapidly. Landsat 8 imaged the area the day before the fires broke out

The Markup Application is a web-based mapping communication tool that allows users to suggest edits, or “markups”, to the National Hydrography Dataset, or NHD, Watershed Boundary Dataset, or WBD, and High Resolution National Hydrography Dataset Plus, or NHDPlus High Res.
 

The Landsat archive has added its 8 millionth scene. 

This stunning image was captured by Landsat 8 on July 28, 2018. It shows the coastline of Nordaustlandet, the second-largest island in Norway’s Svalbard archipelago.

Most of the island is covered by massive white ice caps. The exposed rocky coast appears in reddish brown, peppered with blue and black lakes

Title: Iron Mountain, California: An Extreme Acid Mine Drainage Environment

• "The world's most acid water" — explaining negative pH
• Colorful mineral salts that store metals and acidity in underground mine workings
• Microbial iron oxidation and formation of pipe scale in the water treatment system
• Challenges and successes of

Landsat sensor technology has come a long way since the days of the Return Beam Vidicon cameras on the first three Landsat satellites. Known as the RBV, it wasoriginally intended to be the satellites’ primary sensor. But the Multispectral
Scanner, or MSS, became the more stable and superior instrument.

Each week, the Earth Resources Observation and Science (

Torrential rainfall swamped western Japan in July of 2018. The rain caused mudslides that flooded cities, damaged buildings and rattled the
nation’s infrastructure. More than 170 people died.

At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land

Researchers start drilling an ice core in the Greater Yellowstone Ecosystem.

Black rats were unintentionally introduced to Hawai’i in the late 1800s, most likely as hitchhikers on trading vessels. Since their introduction, they have disrupted native ecosystems by destroying native plants, eating native arthropods, and depredating bird nests. Black rats have contributed to population declines and species extinctions of Hawaiian forest birds, and

This series of images from June 13 through July 7, 2018, show dramatic down-dropping of part of Kīlauea Volcano's summit caldera floor. For weeks,

This video describes the survey requirements for indirect measurements with multiple components, like flow going through a culvert and over a road on top of the culvert at the same time. 
 

In this video, you will learn what and where to survey for a road overflow or broad-crested weir indirect measurement. 
 

On June 30, 2018, at 02:51 PM HST, a collapse/explosion event occurred at Kīlauea's summit. An ash-poor

The USGS is developing methods to improve data collection during floods to gain new insight into the rise and fall of flood waters. In the past, the only data left behind after a flood was how high the water got, or the peak of the flood. This video presents the methodology that hydrologists are using to set up a Continuous Slope-area Reach in remote areas that are

The USGS Unoccupied Aircraft Systems (UAS) team conducted a flight on Kīlauea Volcano's lower East Rift Zone to collect video in the upper lava channel of 

Waterfowl populations in the northern Gulf of Mexico (NGOM) rely extensively on plants that grow under the surface in shallow waters, know as submerged aquatic vegetation (SAV), as a critical food resource in the winter season. SAV roots, shoots, and seeds provide high carbohydrate wildlife food that sustains valuable waterfowl species, including the American Wigeon,
