Historic coastline age raster (AGE 2019)

<b>DESCRIPTION: </b><br> <br> Global paleo drowning map indicating the most recent 500 yr time period a pixel was land. The reconstruction was done using the global bathymetric model (GEBCO 2019) and a state-of-the-art global spatiotemporal sea level curve. The global sea level curve was generated using the software SELEN4 (10.5281/zenodo.3520451) and raster DEMSRE3a (10.5281/zenodo.1637816).<br><br><b>MAPPED CATEGORIES:</b><br><br> from 0 to 260 in bins of 5 (e.g., 0, 5, 10, 15, 20, ..., 260; each bin corresponds to 500 yr) <br><br> 0 = 0 yr BP<br> 5 = 500 yr BP <br> 10 = 1000 yr BP<br> ...<br> ... <br> 100 = 10000 yr BP<br> ...<br> ...<br> 200 = 20000 yr BP <br> ...<br> ...<br> 260 = 26000 yr BP <br><br><b>MAPPED NA VALUES: </b><br><br> No Data = pixel has always been Below (Past) Sea Level since 26000 BP.<br><br><b>SPATIAL RESOLUTION:</b><br><br> The spatial resolution of the dataset is a factor 8 of the original GEBCO. <br><br><b>TEMPORAL RESOLUTION:</b><br><br> Temporal mapping resolution is 500 yr. <br><br><br><div><b>DIRECTORY STRUCTURE:</b></div><div><br><b> </b></div>The dataset is provided in two formats:<br><br><b> 1.
