USGS Studies Hiking Impacts

Most visitors to protected natural areas hike on trails created with hardened treads designed to sustain traffic. However, heavy hiking traffic and use by mountain bikers, motorized vehicles and horseback riders all take their toll. Parks also are becoming more crowded, with long lines of trail users during the popular summer season. More visitors have

Ramp-Up in Antarctic Ice Loss Speeds Sea-Level Rise

Ice losses from Antarctica have tripled since 2012, increasing global sea levels by 0.12 inches (3 millimeters) in that timeframe alone, according to a major new international climate assessment funded by NASA and the European Space Agency (ESA). According to the study, ice losses from Antarctica are causing sea levels to rise faster today than

Drones Aid Precision Agriculture in Brazil

Portal Produtos Agropecuários Ltda in Brazil is using SimActive photogrammetry software in its precision agriculture efforts. Drone data are transformed into useful and pertinent information for farmers with Correlator3D, leading to optimized yields and reduced costs for the agricultural season. The identification of the presence and damage caused by centipedes was one such example. When

Climate Change May Lead to Bigger Atmospheric Rivers

A new NASA-led study shows that climate change is likely to intensify extreme weather events known as atmospheric rivers across most of the globe by the end of this century, while slightly reducing their number. The new study projects atmospheric rivers will be significantly longer and wider than the ones we observe today, leading to

Biologic Changes Dramatically Alter World’s Oldest, Deepest Lake

Eastern Siberia is home to the world’s deepest and most ancient freshwater ecosystem, Lake Baikal. This lake and its surrounding tributaries are one of the largest sources of pure drinking water in the world, containing some of the most diverse and unique organisms. Recent biological changes are causing a major shift in the composition of

What’s Eating Away at the Greenland Ice Sheet?

In the high-stakes race against sea level rise, understanding what’s causing the Greenland Ice Sheet to melt is critical. The problem isn’t just rising temperatures: soot from ships, wildfires and distant power plants, as well as dust and a living carpet of microbes on the surface of the ice, are all speeding up the melting.

East vs. West Coast Earthquakes

Why was an earthquake in Virginia felt at more than twice the distance than a similar-sized earthquake in California? Earthquakes east of the Rocky Mountains can cause noticeable ground shaking at much farther distances than comparably sized earthquakes in the West. A magnitude 5.8 earthquake in 2011 in Mineral, Va., was felt up to 600
