TAG2016Controlled Source Electro-MagneticsCSEM2016-07-18T00:00:0026.15000-44.810002016-07-21T00:00:006 CSEM profiles at about 6 km length each
JC138-15GC15GCGravity corerGC2016-07-18T07:24:0026.15572-44.81650-3553Tension from 4 to 3. The corer has been tilted upside down and many red water came out form the head. The sediments have been probably extremely mixed. Testing sediment thickness for RD2
JC138-16GC16GCGravity corerGC2016-07-18T10:21:0026.15575-44.81620-3553Close to top of Southern Mound. About 1m50. Lot of water for the last one. Testing sediment thickness for RD2

JC138-23GC23GCGravity corerGC2016-07-22T17:31:0026.15675-44.81667-3537NW flank of Southern Mound; Every busy. No one was free to update thos core sheet. Timing and position taken from general log. Hit hard massive sulphides and bended the corer
JC138-27GC27GCGravity corerGC2016-07-23T11:44:0026.15633-44.81360-3524Meteor Hybis dive #9, "Rona Mound"; Tension from 4 to 2.75. 45 cm beige to orange colour
JC138-28GC28GCGravity corerGC2016-07-23T15:08:0026.14278-44.80692-3400Mir mound basin with 2m basin; Tension from 3.8 to 2.76
JC138-29GC29GCGravity corerGC2016-07-23T21:23:0026.17247-44.81473-3430On Shimmering Mound. Around 1.50 m. Very dark brown layer at the end

JC138-37MC37MCMultiCorerMUC2016-07-27T13:00:0026.15920-44.81390-3482East Double Mound. Move a bit in the North, because USBL position is very close to the cliff of South-Estarn Double Mound. Move into the flat area. Only three worked. Did drill on one of them (the longer), the other has been sampled. Very rocky inside
JC138-38GC38GCGravity corerGC2016-07-27T16:38:0026.15217-44.81352-3608Central area with 1 m of sediment. Maybe lost a part because the cc was upside down. Presence of pyrite grains along the core liner
JC138-39GC39GCGravity corerGC2016-07-27T19:55:0026.14380-44.80910-3490MIR delta. 50 cm of sediment. Very sulphidic black sand at the end of the core
