I feel there's a contrast here between the Earth's surface and the
earth's surface. The EEZ globes depict Everyone's Land at the Earth's
surface - only once we get down to the sediment through x metres of
water do the continental shelf rights kick in.
Possible, certainly, to extract the old 1958 200m isobath shelf limit
from the ETOPO5 database, which includes the whole earth's surface,
in contrast to GTOPO30 which gives the land area only.

Beyond my time and wit at present - inshore and archipelagic
baselines become very significant at 12nm (whereas all the but the
largest baselined bays are obscured by the 200nm plot I did, at the
resolution I used). I'd need to drop them into the data by hand
(hard, slow), and then rerun my plot program (just slow).

Good stuff.
