Making art from seafloor surveys
Just as the landscape photographers
want to share the scenes they capture,
marine scientists want to share the
hidden terrains that make the seafloor
so captivating. That is the goal of a new
initiative that uses marine surveys to
create visually stunning artworks.
Visual Soundings is a new website and
art collection showcasing the wonders
of the ocean’s depths uncovered through
multibeam echosoundings (MBES).
The contributors to the site have been
‘listening’ to the seafloor for decades with
increasingly sophisticated technology,
and are now sharing what they have
found to a wider audience. Among the
collections are natural and manmade sea
floor textures reminiscent of—among
other things—a bird’s head, a toppling
wine glass and a couple conversing.
The example depicted above,
“Sediment on the move,” was found in the
waters off the north coast of Ireland. The
region is widely known for its dramatic
rock formation such as the Giant
Causeway. However, further offshore
the geomorphology continues to create
spectacular formations, including these
undulating wave formations and steep
rocky outcrops. They are testament to the
extreme tides and currents of the region.
Dr Lucieer, a marine spatial analyst
behind the Visual Soundings collection,
said seafloor images are usually studied
with a scientific eye rather than from
an artistic perspective, which means the
breathtaking beauty of marine landscapes
is often overlooked.
“We’re familiar with the appearance of
the Moon and even the surface of Mars is
well-documented thanks to NASA’s rovers,
but still only five per cent of the world’s
oceans have been mapped in any detail,”
Dr Lucieer said.
“In recent years, however, new
techniques such as multibeam
echosounders have revolutionised
scientists’ knowledge of the appearance,
shape and structure of the seabed.
“In doing so, they sometimes reveal
startlingly beautiful glimpses of the
seafloor that look more like works of art
than scientific data.”
Simple echosounding and other
techniques have been used for many
years to make maps of the seabed,
primarily for navigation safety, based on
the depth measurements (soundings).
More advanced acoustic techniques,
most significantly multibeam echosounders
have revolutionised our knowledge of the
shape and structure of the seabed over the
last couple of decades. MBES have now
evolved to become the standard system for
mapping the oceans, lakes and rivers.
Traditionally, MBES systems have been
mounted to ship hulls, but more recently
have been adapted to Remotely controled
Underwater Vehicles (ROVS) and
Autonomous Underwater Vehicles (AUVs).
