Stacks: benthic δ18O stacks
Global stacks of benthic foraminiferal δ18O, the reference of the ice volume and deep-sea temperature over glacial cycles and the age model of many reconstructions. Stacks is a records dataset (non-gridded data, see Records): its products, defined in Stacks/records.toml, are prepared files in the form of the CF discrete sampling geometries, written to $FESMDATA_PRODUCTS/Records/Stacks/Stacks-<product>.nc, each with its text form (.txt).

Lisiecki and Raymo (2005): stack of 57 records, doi:10.25921/k88j-0106 | d18O_benthic, d18O_benthic_sd (standard error) (‰) |
0-5.32 Ma (1 kyr to 600 ka, then 2, 2.5 and 5 kyr) |
Stacks-ProbStack |
Ahn et al. (2017): probabilistic stack of 180 records, doi:10.1093/climsys/dzx002 | d18O_benthic, d18O_benthic_sd, d18O_benthic_min, d18O_benthic_max (95%) (‰) |
0-5 Ma (as LR04) |
Both are series of the region “global” without a location (featureType timeSeries, dimension region, lat and lon missing). time is in years before 1950 CE (units “years ago”) on the age model of the stack.

Making the dataset
julia fesmdata.jl record Stacksprepares the missing sources (<Source>/prepare.jl), checks the prepared files and copies them to $FESMDATA_PRODUCTS/Records/Stacks/ with their text forms (--overwrite to replace them).
