Resumen:
Shallow
lakes
may
have
large
areal
extensions
but
for
most
of
the
water
body
depths
are
too
low
for
employing
standard
echosounders
and
boats.
Furthermore,
their
borders
tend
to
be
diffuse
both
because
of
the
presence
of
macrophytes
and
the
wetlands
that
surround
them.
The
Argentina
Pampas
is
covered
by
large
number
of
shallow
lakes,
which
are
understudied
from
the
geomorphologic
point
of
view.
Therefore,
the
aim
of
this
article
is
to
present
new
methodology
for
their
geomorphologic
analysis
as
it
is
a
basic
element
to
further
limnological
studies.
Tests
of
the
methodology
are
carried
out
at
La
Salada
shallow
lake
(Buenos
Aires,
Argentina),
a
site
that
belongs
both
to
the
Pampa2
and
SAFER
networks.
The
methodology
developed
combines
the
use
an
open
source
acoustic
profiler
mounted
over
an
autonomous
small
boat
plus
aerial
high-‐resolution
photography
employing
an
unmanned
hexacopter.
The
former
allows
to
obtain:
i)
an
acoustic
profile
of
lake
bottom
sediment
and
ii)
georeferenced
bathymetry
in
real-‐time.
The
fully
autonomous
hexacopter
can
map
the
coast
and
the
wetlands.
Resulting
3D
maps
can
be
further
integrated
with
sedimentologic
data
take
with
grab
samples
(for
bottom
sediments)
and
a
modified
Phleger
corer
for
subsurface
sedimentary
facies.
The
developed
equipment
has
demonstrated
advantages
over
traditional
bathymetric
methods
both
operating
costs
such
as
integrating
the
physical
data
with
the
geoposition
data.
