A last deglacial climate dataset comprising ice core data, marine data, and stalagmite data.

In this data article, a dataset of paleoclimatic records ranging from 22 to 9 thousand years before present is reported, which is related to the research article entitled "Breakpoint lead-lag analysis of the last deglacial climate change and atmospheric CO2 concentration on global and hemispheric scales" published in the journal of Quaternary International by Liu et al. (2018). In the dataset, 4 δ18O records derived from Greenlandic ice cores, 2 δD records and 7 δ18O records derived from Antarctic ice cores, 32 UK' 37 records and 26 Mg/Ca records derived from marine deposits, and 17 δ18O records derived from cave stalagmites were collected and collated. General and statistical characteristics of these 88 proxy records are showed here. All of the data are stored in separate Microsoft Excel spreadsheets that are available for researchers.

Value of the data

This is a dataset of 88 well-dated high-resolution proxy records compiled from 40 published papers.

This dataset lays the foundation of the study of Liu et al. [1] on the lead-lag analysis of the last deglacial climate change and atmospheric CO2 concentration on global and hemispheric scales.

This dataset can be used in further researches of data synthesis and regional comparison on various spatial and temporal scales over the last deglaciation.

This dataset provides the potential to investigate the discrepancies of different paleoclimatic indicators, the interactions of Earth׳s different spheres, and the rules of the ice age termination from a global perspective.

Data

Tremendous efforts have been devoted to reconstruct the last deglacial climate history across the world; hence to integrate these records distributed in different geographical background is of necessary for the interpretation of the ice age termination from different spatial scales. In the original article [1], we published in the journal of Quaternary International, we collected and collated 88 well-dated high-resolution paleoclimatic records derived from ice cores, marine deposits, and stalagmites to composite global and hemispheric climate stacks. Here, this dataset is reported along with their statistical characteristics. Spatially, the sites of these records cover broadly the globe. Temporally, the average density over the period from 22 to 9 thousand years before present is 136 measurements per hundred years with a total of 17,699 data points. The general and statistical characteristics of these 88 records are showed in Table 1, Table 2, Table 3, Table 4, respectively.

Experimental design, materials and methods

The ice core data and stalagmite data included in this data article were collected from the website www.ncdc.noaa.gov/data-access/paleoclimatology-data/datasets, and the marine data of Alkenone ketone unsaturation index UK′37 and foraminifera Mg/Ca ratio were collected from existing research by Shakun et al. [2]. We extracted the data ranging from 22 to 9 kabp from each collected series and removed the vacant and duplicate values to constitute the dataset.
