The sediment color and composition of each layer in the samples can show what the past climate was like. Dark, organic materials suggest a warm and wet climate.

While the Great Blue Hole has silently recorded history for thousands of years, its latest revelations are a loud warning.

On Earth, ocean tides and winds carry sediment toward the shoreline, where the sediment settles out to form a beach deposit with a characteristic dipping angle. New observations indicate that ...

In 2021, while revelers across America celebrated the fourth of July, three researchers waded through a shallow river delta ...

Analysis of the sediment in Belize’s Great Blue Hole shows a concerning trend. Blue holes, the name for collapsed limestone caves filled with sea water, also serve as important repositories for storm ...

Researchers from Stanford University have discovered a global absence of sediment deposits dating back to the Eocene-Oligocene boundary, around 34 million years ago, challenging established ...

These consist of sediment layers composed of coarse particles, which are different from the finer sediments associated with good weather. In the Caribbean, an international research team has now ...

This sediment core, measuring 98 feet (30 m) long, is the longest continuous record of tropical storms in the area. By analyzing the layers of sediment in the core, the scientists could determine ...

A 30-meter sediment core extracted from the “Great Blue Hole” in Belize offers the longest continuous record of storm ...

Investigations of the sediment layers from the thirty-metre-long core revealed that storms have increased over the long term and that tropical cyclones have become much more frequent in recent decades ...

Sediment-rich ice core layers contained higher major cation concentrations than clean ice layers across all sites, suggesting active meltwater interactions during sediment incorporation. Englacial and ...

Coarse layers are a testimony to tropical storms Some 7,200 years ago, the former limestone island of what is now Lighthouse Reef was inundated by the sea. The layered sediments at the bottom of ...
