The Latest Breaking News from USGS

New Jersey built a massive seawall to protect a highway and beach houses from erosion

In New Jersey, the construction of a seawall has safeguarded properties but has inadvertently resulted in the disappearance of the sandy shoreline. The energy from waves is redirected downwards, which has stripped away sand and left no beach visible even during low tide. This hard engineering tactic disrupts the natural…

The US built nearly 2,000 km of Mississippi River levees; helping erase 4,900 sq km of coastal land

The construction of levees along the Mississippi River has led to significant coastal land erosion in Louisiana by obstructing critical river sediment from reaching coastal estuaries. In an effort to combat this issue, environmental agencies are now reintroducing river mud into the affected bayous. This initiative is focused on rejuvenating…

In 2011, Colorado linked 90% of Lower Gunnison River selenium pollution to farming. 11 years later, farm work cut selenium by 50%, helping the river meet standards today

For years, selenium from irrigated farmland posed a challenge for Colorado’s Lower Gunnison River. Irrigation can mobilize naturally occurring selenium from shale-rich soils and carry it into waterways. Efforts to improve irrigation and reduce selenium runoff began changing that picture. By 2019, the river’s selenium load at Whitewater had fallen…

In Florida’s Everglades, Burmese pythons are helping scientists track pollution

In Florida's Everglades, Burmese pythons are unexpectedly aiding scientists in pollution research. By accumulating harmful substances like PFAS and mercury, these invasive snakes provide a unique opportunity for study. Researchers can examine the tissues of pythons, allowing for insights into environmental health without endangering native wildlife, making these snakes an…

In 2020, Ohio removed a dam from the once-polluted Cuyahoga River; it reopened 39 km of habitat, and scientists later detected 15 additional fish taxa

The removal of the Brecksville Diversion Dam has enhanced river habitats, allowing migrating fish to thrive. Researchers documented the arrival of fifteen new fish species within the lower Cuyahoga River. While native species have successfully reestablished their presence, the advent of nonnative species also marked a significant change in the…

In 2017, USGS injected 13.5 liters of red dye into Ohio’s Sandusky River during a grass carp spawning event; downstream stations measured dye movement

Researchers innovatively utilized red dye to trace the journey of grass carp eggs as they drift along the Sandusky River. By injecting the dye into the water, scientists could accurately assess flow patterns and egg displacement, identifying crucial spawning areas upstream of a dam. This groundbreaking methodology not only enhances…

MapQuest alone refused Trump's demand to rename Lake Ontario, but I still can't leave Google Maps and Apple Maps behind for this one reason

Topping download lists, MapQuest is the new mapping darling, but it's missing one key feature that will keep it from being my go-to navigation solution.

Siberia’s Batagaika Crater has grown for decades as permafrost melts, exposing Ice Age animals and ancient landscapes buried for thousands of years

Deep in northeastern Siberia, a vast scar in the landscape continues to grow as warming temperatures melt the ground that has remained frozen for thousands of years. Known as the Batagaika Crater, and also as a massive thaw slump, the formation is the world's largest permafrost crater. Its expanding walls…

Science says sand isn’t always made from rocks: Some beaches are built from the remains of living things

The next time you stroll along a white tropical beach, remember that the sand beneath your feet may have a far more complex origin than eroded mountains or ancient rocks. Some grains may have traveled through coral reefs, formed within microscopic organisms, broken away from algae or even been created…

Scientists cored Clear Lake, finding ancient pollen records in sediment that reveal how California forests changed with past climate shifts

The sediment cores from Clear Lake present a captivating window into California's forest history over the last half-million years. Research conducted by the USGS and UC Berkeley unveils an unbroken record of climate and vegetation changes, beginning with initial studies in 1973 that traced back 130,000 years. This ongoing research…

In 1983, scientists poured dye into Wyoming’s Popo Agie River before it vanished underground; two hours later, it resurfaced about 3,500 feet away with more water than entered

In Sinks Canyon State Park in west-central Wyoming, the Middle Popo Agie River does something few rivers do: it disappears underground. At a point known as the Sinks, the river's entire flow vanishes into a cave system instead of continuing along an open channel. Downstream, the water reemerges at a…

Nepal floods Day 3: What we know and don't know about the tragedy

Nepal floods Day 3: A devastating flash flood swept through Nepal's Himalayan river valleys after a glacial collapse. Scientists are investigating the precise trigger for the ice and rock avalanche near Langtang Lirung. The resulting debris flow travelled nearly 100 km, causing significant destruction downstream. While some communities received early…

What is a glacial collapse? The science behind the Nepal-Tibet floods

A glacial collapse occurs when a large mass of ice and rock suddenly breaks from a mountain slope, potentially triggering avalanches, debris flows and flash floods. The Nepal-Tibet disaster shows how such cascading Himalayan hazards can travel vast distances and overwhelm conventional early-warning systems.

In 1992, Congress authorized the removal of 2 dams that had blocked salmon for a century. 24 years later, the Elwha River once again flowed freely from the Olympic Mountains to the sea

Elwha River Restoration changed one of America’s most remarkable river recovery stories. Two dams once blocked salmon from reaching upstream habitat in Washington’s Olympic Peninsula. Their removal reopened more than 70 miles of river and tributary habitat. Salmon began returning soon after the dams came down. The river also regained…

In 2017, USGS and MIT researchers dated a magma pulse to 251.9 million years ago. 9 years later, it links to Earth's worst extinction

Earth faced its worst extinction event around 252 million years ago. Volcanic activity in the Siberian Traps is the leading explanation for this crisis. New dating places a major magmatic phase near the extinction's start. Underground magma interacting with sedimentary rocks released greenhouse gases.
