In
water-column
environments
of estuaries
and
other
intertidal
systems,
temporary
blooms
of
photosynthetic
diatoms,
cyanobacteria
and
flagellates
often
occur
in
response
to
nutrient
inputs.
The
carbon-rich
organics
(i.e., mainly cells and EPS)
resulting
from
this
overproduction
may
be
deposited
on
intertidal
sandflats
and
mudflats.
This
may
result
in
quickly
developing
hypoxia,
or
anoxia
conditions,
once
heterotrophic
degradation
of
this
material
commences.
