A scientist holds a piece of a coral-reef core that is over 6,000 years old
January 28, 2020

Various clues determine reliable coral samples

This piece of a core sample taken from offshore of the Fort Lauderdale region of Florida is from an elkhorn coral that lived 6,200 years ago. Coral type, orientation of corallites, and evidence of other fauna and characteristics within the core sample are used to determine how reliable the coral sample is to use for past sea-level reconstruction. Here, USGS Oceanographer

Coral-reef core from the USGS core archive

This core sample was taken from an elkhorn coral reef offshore of the Fort Lauderdale region of Florida. Samples from coral skeletons are taken from numerous locations in the core for radiocarbon dating, which tells scientists the age of each coral and of sections within the reef. The corals in this core lived from 7,100 to 6,200 years ago. Coral type, orientation of

Ablation Stake on Wolverine Glacier

An ablation stake which began the summer below the surface of the snow is shown here in the fall, extending far above bare ice surface of Wolverine Glacier, Alaska. A USGS scientist carries a portable steam drill, used to install the stakes in the glacier.

Lassiter Swamp, North Carolina
August 14, 2019

Lassiter Swamp at Merchants Millpond State Park, NC

Tree-ring analyses from Lassiter Swamp, located along a tributary of the Chowan River, indicate that cypress trees have occupied the site for at least 500 years. To extend the record even farther back in time, scientists from USGS, Duke University and East Carolina University are working together with students at C.S. Brown High School STEM in Winton, NC to study sediment
