Analysis of core samples extracted from beneath an ice sheet indicates that the region is extremely responsive to the temperatures characteristic of today’s interglacial period. Researchers involved ...

Lacustrine turbidites offer a reliable record of seismic activity. A typical sedimentary sequence is produced when a turbidity current moves downslope. If the current generates enough energy, this ...

First surveyed in 1998, the Sur Pockmark Fields stretch along California’s central coastline and lie in an area ripe for future wind energy installations. Using a fleet of underwater robots to gather ...

DURHAM, N.C. -- A 25,000-year precipitation record deduced from sediment core samples taken in lofty Lake Titicaca in Bolivia and Peru suggests that, contrary to widely accepted previous analyses, ...

A rediscovered sample of frozen sediment, collected more than 50 years ago, highlights the vulnerability of Greenland’s ice sheet to a warming climate. By Emily Anthes In 1966, scientists at Camp ...

If all goes to plan, the long metal rod of the core sampler will cut down through the soil of the salt marsh like a knife through warm butter. Mike Priddy and David Bruce take their places in the ...

All Huw Horgan wants for Christmas is a geological core sample. For the third year running, Huw and the team of scientists he now co-leads are on a quest that takes them to the farthest reaches of ...

When an earthquake causes a landslide, debris flow, or erosion, it can change the makeup of nearby lakes by introducing larger sediment particles, causing faster sediment buildup, and affecting carbon ...
