Explore our planet through photography and imagery, including climate change and water all the way back to the 1800s when the USGS was surveying the country by horse and buggy.
Hawaiian Volcano Observatory geologist Matt Patrick acquires video of fissure 8 and the lava channel from Pohoiki Road/Highway 132. The video is used to document fountain behavior and lava flow characteristics, and how they change with time.
This animated GIF shows a sequence of radar amplitude images that were acquired by the Agenzia Spaziale Italiana CosmoSkyMed satellite system. The images illustrate changes to the...
Student hydrologist Todd Anderson assisting with water level measurements and purging of a well at a research location at Ellsworth Air Force Base in South Dakota. The groundwater level is measured and the well is purged prior to collecting water-quality samples from wells.
Hydrologic Technician Kammy Durham collecting water-quality samples from a well at Ellsworth Air Force Base for analysis.
Near the coast, the northern margin of the lava flow field is still oozing fresh lava at several points in the area of Kapoho Beach Lots. Smoke marks locations where lava is burning vegetation.
View of the ocean entry (lower left) from this morning's overflight. Lava was entering the ocean across a broad area primarily on the north part of the lava delta. Upslope along the northern margin of the flow field, lava is still oozing from several points in the area of Kapoho Beach Lots. Fissure 8...
The Woods Hole Coastal and Marine Science Center’s Samples Repository provides space and services for processing and sampling of materials and collections.
Cores can be split in-house using a custom-made sediment core splitter, which utilizes two Bosch1 oscillating tools with flush cut blade attachments mounted to a sliding carriage that moves over a...
The Woods Hole Coastal and Marine Science Center’s Samples Repository provides space and services for processing and sampling of materials and collections. Sample photography uses a Nikon1 D90 SLR camera mounted to the ceiling directly above the layout table in the sample preparation area. This camera is connected to a designated computer workstation and can be...
Student hydrologist Wyatt Tatge assisting with water level measurements and purging of a well at a research location at Ellsworth Air Force Base in South Dakota. The groundwater level is measured and the well is purged prior to collecting water-quality samples from wells.
Lava continues to enter the sea along the southern Kapoho coastline. Lava enters the ocean primarily through an open channel, but also along a 1-km (0.6 mi) wide area. Also visible in the image (center right) is an area at the northern margin of the flow field that is oozing fresh lava at several points in the area of Kapoho Beach Lots.
A small overflow from the lava channel (left side of image) captured by an Unmanned Aircraft System (UAS). Small overflows on both sides of the channel occurred shortly after midnight in the uppermost part of channel. None of these overflows extended past the existing flow field.
Hydrologic technicians Sarah Davis and Jackie Eldredge preparing for a discharge measurement of the Moreau River near Faith, SD (streamgage 06359500). During high flows, the USGS uses a tractor to assist in the discharge measurement where other technology like acoustics will not work due to the high sediment within the stream and where a heavy weight is needed to keep the...
Hydrologic technician Sarah Davis preparing for a discharge measurement of the Moreau River near Faith, SD (streamgage 06359500). Sarah is ensuring that the meter and weight enter into the river properly. During high flows, the USGS uses a tractor to assist in the discharge measurement where other technology like acoustics will not work due to the high sediment within the...
Comparison of photographs taken on June 13 and 26 from near Keanakāko'i Crater overlook in Hawai'i Volcanoes National Park shows a subsidence scarp that formed as the Kīlauea Crater floor subsided. Scientists estimate the dramatic dropping of the crater floor in this area occurred sometime between June 23 and 26. The view is to the west. Halema‘uma‘u crater is in upper...
Recent explosive events haven't produced significant ash plumes from the summit, but downwind communities may still experience ashfall when previously erupted ash is remobilized. On authorized permission from Hawai‘i Volcanoes National Park, our Unmanned Aircraft Systems crew is conducting gas measurements at Pu‘u ‘Ō‘ō. They snapped this photograph from Chain of Craters...
Lava from fissure 8 is entering the sea this morning on the southern portion of the flow front primarily through the open channel, but also along this 1 km (0.6 mi) wide area with multiple laze plumes from smaller oozing lobes.
USGS Hawaiian Volcano Observatory geology field crews maintain watch over the eruptive activity in the lower East Rift Zone and at Kīlauea's summit. Here, a geologist documents the behavior of lava as it exits the Fissure 8 cone. Lava enters the upper channel traveling as fast as 30 km/hour (18 mi/hour).
USGS scientists Kim Besiner, John Solder and Kate Wilkins collect groundwater samples at Grapevine Main Spring.
Scientists traveled to the remote locations along the south rim of the Grand Canyon to assess the potential effects of mining along the Coconino Plateau and groundwater withdrawals associated with increasing populations.
A group of USGS and National Park Service scientists above Granite Gorge on route for 56 miles and 20,000 vertical feet along the south rim of the Grand Canyon to collect groundwater samples from three springs.
Scientists in this photo (left to right) are Christina Bryant, Kim Beisner, John Solder and Kate Wilkins.
USGS scientist Joel Unema hikes to National Canyon Spring to collect groundwater samples from a remote location near the south rim of the Grand Canyon. Joel Unema was part of a group of USGS and National Park Service scientists that rafted 150 miles in nine days to better understand natural resources.
USGS scientists Tom Porter and Joel Unema warm up in the sun as the scientific expedition moves downstream to the next sample location.
The group of USGS and National Park Service scientists rafted about 150 miles in nine days on the Grand Canyon portion of the Colorado River to collect groundwater samples from springs in remote locations.
USGS scientist Nick Voichick rafted about 150 miles in nine days on the Grand Canyon portion of the Colorado River to collect groundwater samples from springs in remote locations.
USGS field crews track activity in and around Leilani Estates in Kīlauea Volcano's lower East Rift Zone. Observations are also collected on a daily basis from cracks in the area of Highway 130, shown here (no changes in temperature, crack width, or gas emissions have been noted recently).
