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.
 

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.

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.

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.

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 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 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. 
 

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.

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.

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. 

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.

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.

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.

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.

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 patented “Handheld Underwater Suction Sampler” is shown here with a sample collection net attached. The sampler was initially called the "Vasco Explorer." USGS biologists from Flagstaff, Arizona, are researching food sources for fish such as the rainbow trout, which are stocked in the Glen Canyon stretch of the Colorado River.

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.
