DATA:

dat.RDS: ForCenS planktonic foraminifera assemblages (Siccha and Kucera, 2017, Sci. Data, https://doi.org/10.1038/sdata.2017.109) and SST data (World Ocean Atlas 2001, Stephens et al. 2002).

fossil_data.RDS: fossil planktonic foraminifera assemblages. Core MD95-2040: https://doi.pangaea.de/10.1594/PANGAEA.66811; core M35003-4: https://doi.pangaea.de/10.1594/PANGAEA.55756; MARGO LGM: https://doi.pangaea.de/10.1594/PANGAEA.227329.

CODE:

taxon_ranking.R: determine species ranking (calls random_Mat.R)

many_TFs.R: build transfer functions (calls many_MAT.R and many_WA.R)

assess_ranking.R: explore species ranking

reconstruct_SST.R: predict SST based on fossil assemblages. Use increasing number of transfer functions based on species ranking
