Temperature and hydrological data for the last 18,000 years from Lake Nong Thale Prong, Southern Thailand

Barbara Wohlfarth, Rienk Smittenberg

Data from a sediment core from Nong Thale Prong, Southern Thailand, including radiocarbon data, plant macrofossil and charcoal data, bulk geochemistry, leaf wax hydrogen and carbon isotopes used to reconstruct past vegetation and hydroclimate, together with the relative abundance of glycerol-dialklyl-glycerol-tetraethers used as a proxy for past temperatures.

The data is used to reconstruct, and get more insight in, the climate evolution of the SE Asian maritime continent, in response to sea level rise, greenhouse gas concentration, and orbital forcing, over the deglacial and Holocene time period from 18,000 BP to the present.

Data description

Downcore data of core CP3 from lake Nong Thale Prong, Southern Thailand, provided in one xlsx spreadsheet file with eight data tables in separate tabs. The data are also provided in eight comma-separated values (csv) files:

• Table 1. Composite stratigraphy
• Table 2. Radiocarbon data
• Table 3. Plant macrofossil and charcoal data
• Table 4. Bulk geochemistry: TOC, TN, LOI, bulk δ¹³C and bulk δ¹⁵N
• Table 5. Leaf wax δD
• Table 6. Leaf wax δ¹³C
• Table 7. GDGTs and reconstructed MAAT
• Table 8. Surface Core GDGTs, reconstructed MAAT, leaf wax δD and instrumental MAAT

Explanations of abbreviations are provided in a separate readme tab in the xlsx file (and in a separate csv file).

Note that the xlsx file contains equations in some columns, while the csv files only contain text and numbers. Also, the number of decimals is larger in some columns in the xlsx file, compared to the corresponding columns in the associated csv files.
