In jfieberg/Data4Ecologists: Data Assoicated with Statistics for Ecologists

PolikSST

Format

A data frame with 139 rows and 8 variables:

Site

integer Location where the core was taken during Leg 160 of the Ocean Drilling Program

Sapropel

character Three sapropels sampled: S3 (81 ka), S5 (124 ka), and i-282 (2.943 Ma)

mbsf

double Meters below seafloor, i.e. the depth of the sample

d15N.TN

double The nitrogen isotopic value of the bulk sediment, in permil

TEX86.SST

double SST reconsctructed using the TEX86 method, in degrees C

Uk37.SST

double SST reconsctructed using the Uk37 method, in degrees C

Temp.Anomaly

double The difference between TEX86 and Uk37 SST reconstructions \itemSedimentcharacter Whether the sample comes from inside the sapropel or from the surrounding, carbon-poor marl sediment

These data come from the following publication:

Polik, C. A., Elling, F. J., & Pearson, A. (2018). Impacts of paleoecology on the TEX86 sea surface temperature proxy in the Pliocene‐Pleistocene Mediterranean Sea. Paleoceanography and Paleoclimatology, 33(12), 1472-1489. PolikSST Sea-surface temperature (SST) data reconstructed using two different molecular signatures datasets
