How big is the Gulf of Ob?
About 47,234 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Gulf of Ob would be land if sea level dropped?
With the sea 10 m lower, about 30,416 km² (64.4%) of its water would be land. At 6,000 m lower, 100% would be. This is a simple bathtub model that lowers the sea evenly everywhere.
