at the Foot of the Page: the sediment in the
Ganges delta is so thick (20 km in some places)
that it depresses the Earth's crust (it's sinking
about 6 mm/yr under the coast) and weakens the
local gravitational field, which weakening
means that, for reasons that are entirely beyond
my comprehension, sea levels are expected to rise
more slowly in the Bay of Bengal than elsewhere
in the world.


The extra mass depresses the Earth's crust, but
weakens the local gravitational field?

Possible.

Depressing the crust is accomplished mostly by the total mass of the thing,
I imagine, and it's really big.

The local gravity is mostly affected by the density of what's nearby, and
the sediment must be somewhat fluffy, at least compared to igneous rock (I
think).

But I don't pretend to understand the thing about sea level rise, either.
