The slowing of wave action and currents means
that seagrass beds tend to accumulate sediment.
However,
this is not universal
and depends
on the currents
under which the bed exists.
Seagrass beds
under the influence of strong currents
tend to have many of the lighter particles,
including seagrass debris,
moved out,
whereas beds
in weak current areas
accumulate lighter detrital material.
It is interesting
that temperate seagrass beds accumulate sediments
from sources outside the beds,
whereas tropical seagrass beds
derive most of their sediments from within.
