Mg/Ca proxy based temperature reconstruction for core MD97-2141, originally published in Rosenthal et al. (2003), extracted from Shakun et al. (2012).
N41.proxy
A data frame with 216 rows and 4 variables:
Published.age | |
Age in yr BP | Published.temperature |
Reconstructed temperature in degrees C | Sed.acc.rate.cm.ka |
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.
