Cladophora sampling site with brick marker and quadrat. Divers put cladophora samples from inside quadrat into bags to take back to the lab.
 

Diver point of view from above the dive camera system. This is a transect over rocky substrate with some cladophora on the bottom of Lake Ontario.
 

Quadrat for sampling cladophora with gobies swimming around. There is another quadrat in the distance for a different sampling site.
 

Diver completing a transect with the dive camera while another diver stands on the center pivot to keep it upright. The transect is a circle and is being controlled with the line attached to the pivot.
 

Diver travelling along the surface of the lake along with the dive camera system. The crew on the boat are there to meet the divers along with pulling the center pivot back onto the boat with the help of the davit.
 

Smallmouth bass swimming near lake bottom. The camera pans up a couple times to show the center pivot where the diver is holding on.
 

An Unmanned Aircraft Systems overflight of fissure 8 on August 21, 2018, showed no incandescence within the cinder cone. Minor amounts of gases, primarily steam, rose from the north wall of the cinder cone and from areas along the lower East Rift Zone. The interior walls of the fissure 8 cone and lava channel are slumping downward and inward. The cinder cone was about 50 m

A total solar eclipse darkened the skies over the United States on Aug. 21, 2017.

Fourteen states were in the path of totality, a 70-mile-wide band under which the moon fully blocked the sun for just under three minutes.

Oshkosh, a town in the Nebraska Sandhills was a prime location for viewing the eclipse. This Landsat 7 image shows the town at 11:33 a.m.

Changes at the summit of Kīlauea between April 14 and August 20, 2018, were captured by a USGS–Hawaiian Volcano Observatory camera. This time-lapse series includes roughly one image per day. The lava lake within Halema‘uma‘u is visible in April, with overflows onto the caldera floor on April 23. The lava lake drains in early May, followed by explosive activity over the

Descending to the lake bottom to get ready for transects with the camera system and cladophora sampling. Organizing quadrats and sampling bags near the center pivot before sampling.
 

Smallmouth bass swimming in front of the dive camera system during a transect. Camera system is attached to the center pivot by a line in order to follow around in a circle.
 

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

The Unmanned Aircraft Systems (UAS) team assessed conditions at the fissure 8 cone and upper lava channel on August 17, 2018. At the time of the flight, the lava pond within the cone had crusted over with no observed incandescence. The reddish-brown rock inside the cone is the result of oxidation; the interaction of heated rock and gases causes black basaltic cinders to

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. 
 

This 3-dimensional computer model shows the structure of the fissure 8 cone on Kīlauea Volcano's lower East Rift Zone. The model was created from thermal images acquired during a helicopter overflight on August 15, 2018. The cone is currently about 30 m (100 ft) tall with a broad base. The bright white area within the cone is a small pond of lava, now largely crusted over

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.
 

Lava continues to enter the ocean near the Isaac Hale Beach Park on Kīlauea Volcano's lower East Rift Zone. Although lava output from fissure 8 remains low, the ocean entry was still active during HVO's helicopter overflight on August 9, 2018. Numerous small streams of lava were oozing into the ocean near Ahalanui, creating weak plumes of laze. The southern flow margin

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

During this morning's overflight, HVO geologists observed low levels of lava fountaining within the fissure 8 spatter cone and crusted lava in the spillway and channel downstream. The significance of this change is not yet clear. Eruptions can wax and wane or pause for days to weeks before returning to high levels of lava discharge. New outbreaks in the area of the active 

Between mid-May and early August, 2018, the depth of Halema‘uma‘u more than tripled and its diameter more than doubled as magma from Kīlauea's shallow summit reservoir moved into the lower East Rift Zone. Evidence of subsidence is visible in this video, taken during an early morning helicopter overflight on August 6, 2018. Cracks and down-dropped blocks of the caldera 

This lava, erupted from fissure 8 on Kīlauea Volcano's lower East Rift Zone, shows classic pāhoehoe behavior. Exposed to the air, the surface of the flow chills to form a thin crust that can be stretched or broken apart, forming pieces of crust that are "subducted" back into the molten interior. The main sound is wind noise, but crackles can also be heard as flakes of
