this is a readme file for the GISP2 ice core workshop example. This information is also presented at the start of the jupyter notebook (GISP2-MeekerMayewski2002-figurereproduction.ipynb)

# Source Data
- data was downloaded from <https://www.ncdc.noaa.gov/paleo-search/study/17805> on 6 March 2019 by Jessica Scheick
- no checksums were available for the data, and data was downloaded as individual text files for the B and D (deep) cores, both detailed and non-detailed datasets (4 files total)
- DIF metadata was downloaded separately (also available as a JSON file)
