Harmonized Landsat and Sentinel-2 (HLS) version 2 data are here!

The LP DAAC and the HLS Science Team are pleased to announce the release of Harmonized Landsat and Sentinel-2 (HLS) version 2.0 surface reflectance products. HLS data are composed of observations from Landsat 8 and Sentinel-2 and provide a set of seamless data products that can be utilized as if all

The Dixie Fire has become the largest single fire in California's recorded history. State fire officials don't list it at the top, however. The record is held by the massive August Complex fire of 2020 which burned over one million acres. The term "complex" is used when multiple fires in the same area ignite separately. Designating the fires as a complex allows them to be

The record 2018 wet year in Pittsburgh resulted in widespread landslides throughout the region, many of which caused considerable damage to residential property and transportation infrastructure. The wet year began with a series of storms including two relatively rare multiday winter rainstorms that resulted in both shallow and deep subsurface hydrologic conditions that

The Earth As Art project began in the early 2000s, and its original intent remains the same: to produce images that do not look like satellite images at first glance. Earth As Art shows not only what satellites capture in the visible wavelengths of light you and I can see, but also what’s hiding in the invisible wavelengths that Landsat sensors can detect in the infrared

A broad overview of landslide geology across Pennsylvania, and historical and current work on landslides by the Pennsylvania Survey and others. The diverse geology and topography of Pennsylvania's woods provides a variety of landslide problems beyond the well-known issues around Pittsburgh.

In this lesson, we will provide an overview and demonstrate how to use The National Map’s web services in a mapping application. Although downloading data from The National Map is a popular option for many users, there are numerous situations where it may be preferable to simply call TNM web services into your mapping application. By using the National Map services, you

Meet GEDI! The Global Ecosystem Dynamics Investigation sensor aboard the ISS!

The Global Ecosystem Dynamics Investigation (GEDI) is a full-waveform lidar instrument that produces detailed observations of the 3-dimensional structure of the Earth’s surface. GEDI precisely measures forest canopy height, canopy vertical structure, and surface elevation which enhances

A prolonged dry spell has sparked woes over water availability and wildfire in the western United States.

This stretch of northern California is heavily reliant on man-made reservoirs. The recent history of a single Landsat scene can serve to illustrate the ripple effects of those severely parched conditions. Water levels have dropped in Folsom Lake, Indian Valley

Welcome to the "The I Am A..." series. This is the ninth video in a series of USGS whiteboard animations that highlight USGS careers. The concept is to show "what society (or my mom) thinks I do" compared with "what I really do." One image captures a more whimsical representation of a "scientist" and the second demonstrates a more accurate representation of what we really

During July, Yellowstone caught everyone’s attention with 1,000+ earthquakes located in seven distinct earthquake swarms. The largest swarm occurred beneath Yellowstone Lake and had 764 earthquakes, the largest of which was a Magnitude 3.6. While this seems like a lot of earthquakes, it is not the most Yellowstone has experienced in any given month and the volcano alert

Rock-mass strength is typically assumed to influence geomorphic processes by setting the erodibility of landscapes. However, the contribution of rock-mass strength to topographic form is often overlooked, largely because rock-mass strength is challenging to quantify over the broad spatial scales relevant to geomorphology. Although laboratory tests can be easily conducted

Topic: Building the infrastructure for updating the National Hydrography Datasets with Elevation-Derived Hydrography – Alaska leads the way

Presenters: Steve Aichele, Geographer, USGS User Engagement Hydrography Focus Area Lead, and Amanda Lowe, Supervisory Geographer, USGS Topographic Applied Research Section Chief

During a recent dive on the New England Seamount chain off the North Atlantic coast, researchers aboard the NOAA Ocean Exploration Expedition, North Atlantic Stepping Stones, discovered a marine geological feature known as a ferromanganese (Fe-Mn) nodule field in the saddle between two peaks of Gosnold Seamount. These seamount-hosted nodules were an exciting find, since Fe

Title: Invasive Species - Lizards, Treesnakes, and Burmese Pythons, Oh My!

By Amy A. Yackel Adams and Andrea F. Currylow

• Relocation of species from their home ecoregions can wreak havoc in novel habitats
• Invasive reptiles around the world have negatively impacted many ecosystems and biodiversity
• We look at examples of Brown Treesnakes,

In 2015, the Washington Geological Survey received legislative funding to start a Landslide Hazards Program (LHP). The LHP has three primary functions: landslide inventory mapping, post-wildfire debris flow assessments, and emergency response. This presentation will include an overview of the LHP and our products and discuss how the program has evolved over the last 6

One of the most cratered landscapes on Earth is part of the Nevada Desert called Yucca Flat. Landsat 8's near-infrared and short wave infrared imaging shows the pockmarked surface perhaps more reminiscent of other planetary bodies than Earth.

The craters are relics from decades of nuclear tests conducted by the U.S. government since the early Cold War. An aerial

Join USGS researchers Jason Chaytor and Kira Mizell as they virtually participate in a NOAA Ocean Exploration expedition to the depths of the North Atlantic.

The 2021 North Atlantic Stepping Stones: New England and Corner Rise Seamounts expedition runs from June 30 to July 29. At-sea and shore-based science teams will study deep-water habitats in the high seas,
