The Total Water Level and Coastal Change Forecast has continually expanded since real-time forecasts began in 2015. In 2020, new regions of the Gulf and South Atlantic coasts were added to the forecast and officially approved for use in National Weather Service Forecasts. The Total Water Levels and Coastal Change (TWL-CC) Forecast Viewer is a web-based tool that visualizes

The nontidal network mapper is a story map that provides the primary findings for nitrogen, phosphorus and suspended-sediment trends, and gives the user tools to further examine the results for river basins and individual sites. Data used in the mapper, and the methods used to compute trends and loads, can also be accessed from the tool.

The USGS Active Groundwater Level Network includes about 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months. The animation shows a daily snapshot of water-level statistics in the network for August 2020

Research scientist Lesley DeFalco works on native and invasive annual plant sampling at the site of the Tramp Fire,one of 12 fires for which the USGS and the BLM are implementing landscape scale restoration treatments.

This Coastal Change Storm Hazard Team forecast was made at 4 AM CDT August 26, 2020 and shows forecast beach erosion at the base of the dunes (the strip of colored bars closest to the coast), overwash (middle strip) and inundation (outer strip) from Hurricane Laura.  The model accounts for sandy beaches and barrier islands and does not include marshes, forested or sea

The USGS Forest and Rangeland Ecosystem Science Center (FRESC) held a groundbreaking ceremony on August 25, 2020 at the Idaho Water Science Center (IDWSC) in Boise, Idaho. FRESC is moving their Snake River Field Station, presently located on the Boise State University campus, to the IDWSC campus and building a new facility for the USGS Pacific Northwest environmental DNA

A scanned image of Rocky Mountain juniper deadwood sample GGR100 collected in the northern part of Yellowstone National Park under permit YELL-5582.  The full length of this sample covers the time period 723-1792 CE. Since climate influences tree growth and the width of annual rings, the relation between ring widths and recent instrumental climate records (air temperature

Nā‘ālehu radome, 39 ft (about 12 m) in diameter. The radar dish inside is 28 ft (8.5 m) across. USGS photo by C. Neal on July 27, 2019. More details on the technical specifications of this instrument can be found at this website (https://www.roc.noaa.gov/WSR88D/Engineering/NEXRADTechInfo.aspx).

Radar image of the May 17, 2018 eruption of ash from Halema‘uma‘u Crater. This image is a slice through the cloud at an altitude of 14,000 ft (4 km) above sea level at 4:12 a.m., HST. The colors scale is radar reflectivity, a measure of the size of the particles and their concentration within the ash cloud. Colors indicate the different echo intensities or reflectivity.

Example of the Landsat 8 OLI/TIRS Collection 2 level-1 product. This Landsat 8 image was acquired on August 18, 2020 over Lake Everard and Lake Harry in southern Australia and is shown as a false color composite using the shortwave infrared, near infrared, and red bands (bands 6,5,4).

Cross section through the Earth showing the ground surface with an embedded pressure source (red circle)—the so-called “Mogi model”—beneath the ground.  When this pressure source expands, the ground surface inflates like a balloon (the opposite occurs when the pressure in the source decreases).  Dashed black line shows, in an exaggerated way, how the shape the surface

Photo looking north from the north shore of Yellowstone Lake. The photo was taken from a level bench, or terrace, which marks a previous high stand of the lake.  In the middle distance (between the two red lines), the ground slopes up to second, higher-level terrace that indicates an even higher past lake level.
