(21-08-09) The Oceana’s research catamaran studies the
sea bed of the Canary Islands on expedition which will conclude next
October and it’s supported by the Biodiversity Foundation.
The Oceana
Ranger research vessel sets sail to study the sea bed of the
Canary Islands and gather information to propose designation
of new marine protected areas. The objective of the expedition
is to contribute information to help Spain protect 10% of its
marine environment by 2012, as required by the United Nations
Convention on Biological Diversity.

The Canary Island expedition,
which will conclude in mid-October, is a project supported by the
Biodiversity Foundation through its official announcement for aid
and will be carried out after having studied previously the coasts
of the Iberian Peninsula.
Oceana will study the seamounts
of the Canary Islands, as well as the sea bed of El Hierro, La Palma,
La Gomera, Tenerife, Gran Canaria, Fuerteventura and Lanzarote. A
team of professional divers will work to photograph and film the
areas up to 40 meters depth. After that depth, an underwater robot
(Remote Operated Vehicle or ROV) will be used to film down to 500
meters depth, transmitting the images to the ship in real time for
later species identification.
The photographs taken during the expedition
will be included in a database along will all relevant information
about the species (common and scientific names, habitats, activity,
locations, etc.). Furthermore, the video footage will be reviewed
and analyzed to make it easier to find the species and use the footage
for distribution and administrative purposes. All images recorded
with the ROV include the geographic coordinates and depth at which
they were taken.
The
information gathered will be used to compile a scientific and technical
report on the state of the marine ecosystems. The report will draw
conclusions about the conservation state of the sea bed studied and
information on the threats that affect them, and make recommendations
for protection, including the designation of new marine protected
areas.
INFORMATION ABOUT PLACES HAVE NEVER BEEN
STUDIED
Ricardo Aguilar, Director
of Research at Oceana Europe, explains, "Most of the Canary
Islands sea bed remain unexplored since the continental shelf is
small and quickly drops down to 3,000 meters. This makes it complicated
to know their state of conservation or identify areas of key importance
in terms of marine ecology. The Ranger expedition will sail around
the main islands to evaluate the state of the already-protected areas,
detect risk factors and identify new areas that deserve protection.
The difference from other projects is that images will be taken and
information will be compiled about places that, up to now, have never
been studied."
Research projects like this
one by Oceana are used by different administrations to designate
new marine protected areas or expand already existing ones. Currently,
there are only three Marine Reserves in the Canary Islands: La Graciosa
and the islands of northern Lanzarote (70,700 hectares), La Restinga
/ El Hierro - Mar de las Calmas (750 ha) and La Palma Island (3,719
ha). A new reserve is being created in La Gomera and there is also
the Natural Park of the Chinijo Archipelago (Lanzarote, 37,151 ha).
In 2005, the EU prohibited
destructive fishing practices -including bottom trawling- in approximately
650,000 square kilometers around the Canary Islands, Madeira and
the Azores. But this area does not include Concepción Bank, near
Lanzarote, a seamount for which the international marine conservation
organization has requested protection many times.
