On this Picostat.com statistics page, you will find information about the edcT data set which pertains to EPICA Dome C Ice Core 800KYr Temperature Estimates. The edcT data set is found in the DAAG R package. You can load the edcT data set in R by issuing the following command at the console data("edcT"). This will load the data into a variable called edcT. If R says the edcT data set is not found, you can try installing the package by issuing this command install.packages("DAAG") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the edcT R data set. The size of this file is about 197,585 bytes.

EPICA Dome C Ice Core 800KYr Temperature Estimates

Description

Temperature record, using Deuterium as a proxy, from the EPICA (European Project for Ice Coring in Antarctica) Dome C ice core covering 0 to 800 kyr BP.

Usage

data(edcT)

Format

A data frame with 5788 observations on the following 5 variables.

Bag

Bag number

ztop

Top depth (m)

Age

Years before 1950

Deuterium

Deuterium dD data

dT

Temperature difference from the average of the last 1000 years ~ -54.5degC

Details

Temperature was estimated from the deuterium data, after making various corrections.
