Name	National Lacustrine Core Facility
Established	1990s
Location	United States
Type	Repository and research center

National Lacustrine Core Facility is a centralized repository and research center for lake sediment cores, focusing on long-term preservation, analysis, and distribution of lacustrine archives. The facility supports reconstruction of environmental change through coordinated sampling, geochemical profiling, and chronological methods, serving researchers from universities, museums, and federal agencies. It collaborates with national collections, observatories, and research programs to integrate sedimentary records into regional and global syntheses.

History and Establishment

The facility was formed amid initiatives by agencies and institutions including the National Science Foundation, United States Geological Survey, Smithsonian Institution, University of Minnesota, and regional partners to standardize sediment core curation and enable comparative paleolimnology. Early planning drew on expertise from field campaigns associated with projects such as the International Geophysical Year, Lake Baikal research programs, and basin-scale studies led by teams from Cornell University, University of Wisconsin–Madison, and the University of Minnesota Duluth. Funding, governance, and site selection involved consultations with representatives from the National Oceanic and Atmospheric Administration, U.S. Forest Service, and state geological surveys culminating in the facility’s operational launch in the late 1990s and expansion during the 2000s alongside networks like the Global Lake Ecological Observatory Network and the Long Term Ecological Research Network.

Mission and Objectives

The mission emphasizes long-term stewardship to support paleoenvironmental, paleoclimate, and limnological research for institutions such as Yale University, University of Cambridge, and Peking University. Objectives include standardized preservation aligned with practices from the Natural History Museum, London, data sharing consistent with policies of the National Institutes of Health and National Science Foundation, and facilitating interdisciplinary studies involving investigators from the Max Planck Society, U.S. Environmental Protection Agency, and international partners like the European Geosciences Union. The facility aims to enable reproducible chronologies, support graduate training tied to programs at Columbia University and University of California, Berkeley, and contribute samples to collaborative syntheses led by groups at Harvard University and Ohio State University.

Facilities and Collections

Physical infrastructure includes cold-storage vaults comparable to repositories at the Lamont–Doherty Earth Observatory and the British Antarctic Survey core facilities, imaging suites modeled after those at the Natural History Museum of Denmark, and clean labs following protocols used by the Woods Hole Oceanographic Institution and Scripps Institution of Oceanography. The collection comprises thousands of cores from North American basins and international expeditions, with holdings connected to projects at Lake Superior research programs, Great Salt Lake studies, and high-latitude campaigns tied to ArcticNet and Antarctic research stations. Curated materials include split cores, archived whole-rounds, freeze-dried subsamples, and thin sections compatible with analyses at centers like the Joint Genome Institute and the Oak Ridge National Laboratory.

Sampling, Processing, and Curation Methods

Standard operating procedures were developed in consultation with experts affiliated with INQUA, PAGES (Past Global Changes) community protocols, and laboratory standards from the International Ocean Discovery Program. Methods encompass piston coring, gravity coring, and freeze-coring techniques practiced by teams from University of Texas at Austin and University of Bergen, followed by non-destructive X-ray CT scanning, magnetic susceptibility logging, and line-scan imaging similar to workflows at the British Geological Survey. Chronology relies on radiometric dating including radiocarbon dating coordinated with labs at National Ocean Sciences Accelerator Mass Spectrometry Facility, tephrochronology cross-referenced using markers from eruptions cataloged by the Global Volcanism Program, and lead-210 dating through collaborations with the Environmental Protection Agency. Curation emphasizes chain-of-custody, metadata standards interoperable with repositories like the PANGAEA data publisher and archive practices used by the U.S. National Archives and Records Administration.

Research Applications and Collaborations

Research spans paleoclimate reconstructions informing studies by groups at Princeton University, University of Colorado Boulder, and ETH Zurich, as well as biogeochemical and ecological investigations in partnership with the Monterey Bay Aquarium Research Institute and the Nature Conservancy. The facility supports multiproxy analyses—diatom stratigraphy connected to taxonomic reference collections at the Natural History Museum, London; sedimentary ancient DNA studies conducted with laboratories at the Max Planck Institute for Evolutionary Anthropology; and geochemical fingerprinting in collaboration with the U.S. Geological Survey. Long-term collaborations include consortium efforts with PAGES, INQUA, and continental programs such as the North American Carbon Program to synthesize lake-based records for policy-relevant assessments led by organizations like the Intergovernmental Panel on Climate Change.

Access, Data Management, and Outreach

Access policies prioritize researchers from universities, museums, and agencies including University of Michigan, University of Minnesota, and Smithsonian Institution with sample request procedures aligned to guidelines used by the International Ocean Discovery Program. Data management follows FAIR principles and uses metadata schemas interoperable with archives operated by PANGAEA, NOAA National Centers for Environmental Information, and the USGS National Water Information System. Outreach and education programs include workshops for students from institutions such as Ohio State University, public exhibits coordinated with the Science Museum of Minnesota, and training modules developed with the American Geophysical Union to build capacity in paleolimnology and curation best practices.
