Large Underwater Experiment Shows that “Turbidity Currents” are Not Just Currents, but Involve Movement of the Seafloor Itself
Turbidity currents have historically been described as fast-moving currents that sweep down submarine canyons, carrying sand and mud into the deep sea. But a new paper in Nature Communications shows that, rather than just consisting of sediment-laden seawater flowing over the seafloor, turbidity currents also involve large-scale movements of the seafloor itself.
Life in Total Darkness–Investigating Underwater Cave Ecosystems
For more than 30 years, scientists have known that remarkably complex ecosystems thrive within underwater coastal caves, habitats that naturally contain no light and very little food or oxygen. Yet, almost nothing is known about the ecology of these systems.
The Development and Demise of Florida’s Coral Reefs
A new study published in the journal Global Change Biology by scientists at the USGS St. Petersburg Coastal and Marine Science Center suggests that unlike most other reefs, the geological decline of Florida’s reefs preceded modern coral-reef degradation by at least 3,000 years.
