Diving number 15 (6 August) of the cruise completed the study of the north wall of the Romanche transform fault. This dive also sampled the base of the south wall. The chosen zone was the… The Romanche wall at the nodal basin
On the 30th of July the objective of the dive was to investigate the damaged zone of the Romanche transform fault. The fault is located inside a deep and wide valley, and the dive profile… Crossing the transform fault: a second dive
The eighth Nautile dive occurred on July 28th. It has been devoted to the study of the inner part (ENE slope) of a NNW-SSE trending massif lying to the South of the transform, to the… The fragment of a detachment fault: in the core of a “Core complex”
The seventh dive took place on July 27th. The purpose of the dive was to explore the western surface of the relief already partly explored during the first dive, a fragment of an old oceanic… The fragment of a detachment fault: the corrugated surface
On Friday, July 26, the goal of the dive number 6 is to cross the transform fault, the active zone between the old northern part and the more recent southern part. The dive profile corresponds… Crossing the transform fault
The 5th Nautile dive of the SMARTIES cruise occurred July 25th. The dive follows the northern section of the transform fault, on the same side as the 2nd and 4th dives exploring a section of… A transect along the steep part of the northern section of Romanche transform: a section of the upper oceanic crust
The fourth dive took place on July 24th. The profile is within the deepest part of the northern section of the transform fault. We had two objectives: (a) first to look for a potential contact… A transect along the wall of the Romanche transform: the base of the escarpment
The third Nautile dive of the SMARTIES cruise was designed on a ridge similar to the one studied during the 1st dive, west of the MAR axis and south of the transform fault. The studied… An old detachment surface: mantle rocks at the sea floor. Dive number three.
The second dive, carried out on July 22nd was launched at 10:40 am. This dive being shallower than the first one, 2950 meters, the descent was shorter, arriving at the bottom around 12:20 pm. The… Second dive: a transect along one of the walls of the Romanche
The first few days of the SMARTIES mission have been devoted to the deployment of 19 Ocean Bottom Seismometers (OBSs) in the western Romanche Transform Fault and its intersection with the Mid-Atlantic Ridge (MAR). These… Scientific objectives of the OBS experiment
On July 21st we are at the position of the first dive of the cruise. The Nautile, refit at the beginning of the year, must be qualified for great depths. We thus chose the first… The first dive – objective 6000 m
During the cruise, we are going to dive with the Nautile. It is a submersible that can dive until 6000 meter deep so we can collect rocks samples and record high quality photographs and videos… Visiting the Nautile
