The associated NCEI study type is Lake. The data include parameters of climate reconstructions|insect|paleolimnology with a geographic location of Arctic Ocean. The time period coverage is from 11000 to 0 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data. Records of past climate and environment derived from lake sediment records. Parameter keywords describe what was measured in this dataset. Additional summary information can be found in the abstracts of papers listed in the dataset citations. completed NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact NOAA World Data Service for Paleoclimatology Data Center Contact 828-271-4800 303-497-6513 325 Broadway, E/NE31 Boulder CO 80305-3328 USA paleo@noaa.gov pointOfContact https://www.ncei.noaa.gov/pub/data/paleo/webimages/pc-default-lake.png Paleoclimatology - Lake PNG Earth Science > Climate Indicators > Paleoclimate Indicators > Ocean/Lake Records theme Global Change Master Directory (GCMD) Science Keywords 2025 revision 22 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

ABSTRACT SUPPLIED BY ORIGINATOR: We present a systematic compilation of previously published Holocene proxy climate records from the Arctic. We identified 170 sites from north of 58N latitude where proxy time series extend back at least to 6 cal ka (all ages in this article are in calendar years before present – BP), are resolved at submillennial scale (at least one value every 400 ± 200 years) and have age models constrained by at least one age every 3000 years. In addition to conventional metadata for each proxy record (location, proxy type, reference), we include two novel parameters that add functionality to the database. First, "climate interpretation" is a series of fields that logically describe the specific climate variable(s) represented by the proxy record. It encodes the proxy-climate relation reported by authors of the original studies into a structured format to facilitate comparison with climate model outputs. Second, "geochronology accuracy score" (chron score) is a numerical rating that reflects the overall accuracy of 14C-based age models from lake and marine sediments. Chron scores were calculated using the original author-reported 14C ages, which are included in this database. The database contains 320 records (some sites include multiple records) from six regions covering the circumpolar Arctic: Fennoscandia is the most densely sampled region (31% of the records), whereas only five records from the Russian Arctic met the criteria for inclusion. The database contains proxy records from lake sediment (60%), marine sediment (32%), glacier ice (5%), and other sources. Most (61%) reflect temperature (mainly summer warmth) and are primarily based on pollen, chironomid, or diatom assemblages. Many (15%) reflect some aspect of hydroclimate as inferred from changes in stable isotopes, pollen and diatom assemblages, humification index in peat, and changes in equilibrium-line altitude of glaciers. This comprehensive database can be used in future studies to investigate the spatio-temporal pattern of Arctic Holocene climate changes and their causes. The Arctic Holocene data set is available from NOAA Paleoclimatology.
