Description

Mg/Ca proxy based temperature reconstruction for core MD97-2141, originally published in Rosenthal et al. (2003), extracted from Shakun et al. (2012).

Usage

N41.proxy

Arguments

Format

A data frame with 216 rows and 4 variables:

Published.age
Age in yr BPPublished.temperature
Reconstructed temperature in degrees CSed.acc.rate.cm.ka

Details

Published age and published temperature were extracted from Shakun, J. D., Clark, P. U., He, F., Marcott, S. A., Mix, A. C., Liu, Z., … Bard, E. (2012). Global warming preceded by increasing carbon dioxide concentrations during the last deglaciation. Nature, 484(7392), 49–54. tools:::Rd_expr_doi("10.1038/nature10915").

Sediment accumulation rates were estimated by fitting splines to the published age and depth estimates.
