IceCores: ice core records
Time series at Antarctic and Greenland ice core sites over glacial cycles: water isotopes, temperature, accumulation, dust and surface elevation, and the AICC2023 ice core chronology. IceCores is a records dataset (non-gridded data, see Records): its products, defined in IceCores/records.toml, are prepared files in the form of the CF discrete sampling geometries, written to $FESMDATA_PRODUCTS/Records/IceCores/IceCores-<product>[-<part>].nc, each with its text form (.txt).

IceCores-AICC2023-<core> |
Bouchet et al. (2023): AICC2023 chronology, doi:10.1594/PANGAEA.961017; one file per core | EDC, EDML, NGRIP, TALDICE, Vostok | age_ice_aicc2023, age_gas_aicc2023 and their _sd, age_ice_aicc2012, age_gas_aicc2012, acc, thinning, lid, delta_depth (profiles along depth) |
to 813 ka (EDC) |
The records are time series at fixed sites (featureType timeSeries, dimension station, with lat, lon, site_name, and z_srf where the source gives it); the AICC2023 files are profiles along depth (featureType profile); GLT_syn is a series of a region without a location. time is in years before 1950 CE (units “years ago”), on the time scale of the source (in the comment of time); ages b2k (before 2000 CE) are converted by subtracting 50. Water isotopes are in ‰ (units 1e-3); temperature anomalies tas_anom are relative to the present (see each source).
time_aicc2023: the records of EDC, EDML, TALDICE, Vostok and NGRIP with depths also have the ages on AICC2023 (Bouchet et al., 2023), interpolated linearly in depth in the AICC2023 table of the core (IceCores-AICC2023-<core>); missing outside the table. WAIS Divide has AICC2023 ages from the WAIS Divide-EDC tie points of AICC2023 (10-57 ka).

Making the dataset
julia fesmdata.jl record IceCoresprepares the missing sources (<Source>/prepare.jl), checks the prepared files and copies them to $FESMDATA_PRODUCTS/Records/IceCores/ with their text forms (--overwrite to replace them). The sources with AICC2023 ages prepare Bouchet2023_AICC2023 first if needed.
Downloads
