Field collection
One productive coring trip provides >50-m of sediment for analyses and curation. The Quaternary Lab currently stores ~350-m of soft sediment cores collected between 2005 and 2025.

Lake sediment coring
Manual piston coring is used for lakes <20-m water depth and can obtain up to 15-20m sediment core.

Bison Lake, Colorado
The past 150 years of lake sediment accumulates in 35cm to construct a multi-annual isotope record that was compared with the 20-year annual tree-ring record.
