Capabilities

By Quaternary Research Facility

The Quaternary Lab Facility has expertise, tools, and equipment to carry out lake and peatland sediment coring, core processing and archival storage. This includes a variety of coring systems and platforms, core processing space, tools, and equipment, and walk-in cold room. 

The lab is also designed for sample pre-treatments for subsequent analyses in other laboratories such as radiocarbon and radiogenic geochronology, stable isotope geochemistry, sedimentology, and paleoecological analyses. 

 

Field Equipment

Sources/Usage: Public Domain. View Media Details
Lake sediment coring : A percussion piston coring system is used for >20-m water depth and can obtain up to 20-m of sediment core

 

Media
two photos of ice coring work on a frozen lake: a hand holds a filled coring tube upright and another core laid horizontally
Sources/Usage: Public Domain. View Media Details
Lake sediment coring : Manual piston coring is used for lakes <20-m water depth and can obtain up to 15-20m sediment core.

 

Media
an array tubes containing lake coring samples to be processed
Sources/Usage: Public Domain. View Media Details
Field collection: One productive coring trip provides >50-m of sediment for analyses and curation. The Quaternary Lab currently stores ~150-m of soft sediment cores collected between 2005 and 2025.

 

 

Lab Equipment

Media

Sources/Usage: Public Domain. View Media Details
Whole core magnetic susceptibility measurements: Measurements of whole core magnetic susceptibility provide a general stratigraphic profile of sediment layer compositions.

 

 

Media
core photo stand used in the Quaternary Lab Facility
Sources/Usage: Public Domain. View Media Details
Sediment core photography stand: Every split sediment core is photographed to document color, structure and stratigraphy.

 

Media
segmented sediment core from Lake Lucille in Alaska, split into 9 columns, numbered D2 through D10
Sources/Usage: Public Domain. View Media Details
Sediment core photography: Photography of split sediment cores is calibrated for color/light.

Past Perspectives of Water in the West

In the intermountain west, seasonal precipitation extremes, combined with population growth, are creating new challenges for the management of water resources, ecosystems, and geologic hazards. This research contributes a comprehensive long-term context for a deeper understanding of past hydrologic variability, including the magnitude and frequency of drought and flood extremes and ecosystem...

Holocene Hydroclimate of Western North America

The objectives of this project are to reconstruct detailed histories of Holocene hydroclimate and corresponding environmental change from geological archives such as lake sediment, peat, and wood to more fully understand past, ongoing, and future change and its impacts.
