R code for plotting sea level changes over the last 800,000 years.
Just run:
./create-animated-map.sh
or
bash create-animated-map.sh
Sea-level estimates are from the projection of Spratt and Lisiecki (2016). These data are included in the repository and can be found here:
https://www.ncdc.noaa.gov/paleo-search/study/19982
The bathymetry data are from the ETOPO1 1-arc-minute global relief model (Amante and Eakins, 2009), which are here:
