Pollen data from Ruppert Lake, south-central Brooks Range, Alaska

Data from:
Higuera, P. E., L. B. Brubaker, P. M. Anderson, F. S. Hu, and T. A. Brown. 2009.
Vegetation mediated the impacts of postglacial climate change on fire regimes
in the south-central Brooks Range, Alaska. Ecological Monographs 79:201-219.

For each site, Code (CO), Ruppert (RP), Wild Tussock (WK), and Xindi (XI), there
are the six files:

1. xx_age_depth_data.txt – Depth (cm) and age (cal yr BP) from the published
age-depth model.

2. xx_age_depth_fig.pdf – Figure of the age-depth model, ¼ of Fig. 2 in Higuera
et al. (2009)

3. xx_charData.csv – Charcoal data in a CharAnalysis input file. Units are in the
column headers: See https://sites.google.com/site/charanalysis/ for more details.

4. xx_charParams.csv – Parameter file CharAnalysis, with parameters as used in the
original publication. See https://sites.google.com/site/charanalysis/ for more details.

5. xx_charResults.csv – CharAnalysis results file. Units are in the
column headers: See https://sites.google.com/site/charanalysis/ for more details.

6. xx_pollen.xls – Pollen counts for each sample. The tab “pollen_counts” and
“pollen_cm” contains raw the same data as in the tab “data” but in a raw format
used for plotting. Ages associated with each pollen sample have to be obtained
from the “xx_age_depth_data.txt” file, or from the appropriate column in the
“charData” file in the “xx_char.xls” file.

Radiocarbon dates from each site are in the file “Higuera_et_al_2009_Table_B1”
in the folder titled “C14_dates” as published here:
