We arrived at Site U1385 (SHACK-04)

We arrived at Site U1385 located in the Portuguese Margin (Lat. 37° 34.3’N, Lon. 10° 59.6’W) at 04:00AM and the set of 12 hydraulic thrusters was drop down into the water to stabilize the ship.

"There Will Be Mud" on the Core Deck

What could be the title of a forthcoming movie premiering in theatres, become reality and since the first core arrived at the rig floor yesterday around 11h00 PM.

More troubles... and new solutions

This weekend we had a series of problems with the equipment on board the JR. Apart from the situation with the equipment that measures the emission of natural gamma radiation described earlier, we also had some troubles with the equipment used to drill the Hole U1386B (GC-01A).

Turbidite ou contourite ???

Et voilà l’un des points d’intérêt majeur de cette expédition : l’enregistrement des courants sous-marins.

Ces 2 photos montrent chacune un niveau sableux, qui témoignent d’un courant plus fort pour transporter ces particules plus grossières.

Unexpected results... are good results!!!

During the last week we successfully drilled the first site on the Gulf of Cadiz,  just around 30 km southeast of Faro.

How do the scientists choose where to drill?

We had targeted these first two sites (U1386 and U1387) on one of the world’s best known giant elongate drifts that had never yet been drilled - the Faro Drift.

Coring systems and sediment core quality

Once the vessel is positioned at a site, the thrusters are lowered and a positioning beacon is dropped to the seafloor.

Why are we drilling more than one hole at each site?

One of the main objectives of Expedition 339 is to obtain a series of high-resolution, undisturbed, and continuous sedimentary records of the Plio-Quaternary.

Ready to go home!!!

We heard the last "core on deck" of Expedition 339...

On l’a fait !!!

C’est non sans émotion qu’on a accueilli aujourd’hui la dernière carotte à bord de l’expédition ! Pour l’occasion les scientifiques ont porté symboliquement cette dernière venue depuis le pont de forage jusqu’à l’établi de découpe.
