Marine scientist Matthew Costa is used to digging into research—literally. Over the course of his PhD program at UC San Diego’s Scripps Institution of Oceanography, Costa frequently muddied his hands ...

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 ...

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 ...

Elizabeth Thomas, UB assistant professor of geology, holds a sediment core -- a cylindrical sample of lakebed mud. Such samples contain organic matter that can be analyzed to learn about a region's ...

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, ...

Since the discovery 50 years ago of subglacial lakes in Antarctica—some of the least accessible geological features on Earth—scientists have attempted to extract lake bed sediment to learn about the ...

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 ...
