Researchers at the Spanish Institute of Oceanography (IEO) responsible for the research campaign on the island of El Hierro, on board Ramon Margalef, have managed to film the most active volcano Politolana submarine vehicle thanks to a sledge intended for photogrammetry entirely by the IEO and thanks to its relative simplicity and extreme robustness is able to descend to 2000 meters deep in the worst conditions.
Clearly, there is little visibility for the plight of the area. The video is chronological, so we see the approach of the robot and, about 4.40 minutes and can be seen casting a meter away.
On November 3 ended the campaign of the second phase of research on the volcano of El Hierro on board Ramon Margalef, after geophysical work which mapped the area of the eruption by acoustic methods at this stage we used two unmanned underwater vehicles: the 2000 and Liropus ROV photogrammetric sled Politolana.
The latter, designed entirely by the IEO, the only one who has managed to reach the most active of the new volcano on the island of El Hierro, due to the harsh environment, both prevailing strong winds over 30 knots, preventing to properly position the boat, as the physico-chemical characteristics of water, prevented the ROV Liropus to approach the area.
In successive approximations the researchers managed to put the sled just feet away from the volcano's lava flow which was subject to pyroclastic flows from the crater and acidic water (pH 4.8). The vehicle resisted all high-risk dives and has produced valuable information that is being analyzed.
With this vehicle have also been able to study the seabed in the area of the Sea of Calms and the Marine Reserve of La Restinga, between depths of 150 to 750 meters can be seen a progressive contribution of settled material from the volcano that affects a greater or lesser degree biological communities present.
Studies using this vehicle operations and the ROV Liropus 2000 in the area have been directed by the IEO researcher Francisco Sanchez. These works correspond to the second phase of the campaign of Ramon Margalef, which was conducted following geophysical studies of the morphological characteristics of the new undersea volcano. At the moment it develops the third phase of the campaign consists of the study of physico-chemical characteristics of the waters that surround the area of undersea volcanic activity.
