    A beautiful sunny December morning has seen a lot


    A beautiful, sunny December morning has seen a lot of pipes come out of the hole in preparation for logging. As the Sun has set behind the mountains at 13h, the logging lab has started to be installed. By the late evening a successful optical and acoustic televiewer logging has nicely imaged the bottom 60 m, respectively 250 m, of the borehole. Credits go to Andrew, Ludovic, good preparation, and our new winch.

    The crossing of the 500 m depth level has


    The crossing of the 500 m depth level has been celebrated in the early afternoon, when the 6th core out of today's 7 has seen light. The pulling ability of the rig is now fully functional. The current bottom depth is 504.3 m, drilling resumes on Monday. Until then, a geophysical logging program is on the agenda, to evaluate the position of the borehole with respect to the geological structure more precisely.

    Efforts continued overnight and all day to fix the presumably last bug of the new rig. When it drills, cores are produced very quickly, but pulling remains irregular. Six cores produced in the past 24 hours, reaching 483 m depth. Today has seen several visitors on site, in particular the CEO and chief geologist of the drilling company, all in a positive atmosphere.

    The day plan included a rapid change of rigs, which ended up taking the whole day. Nevertheless, the new, strong and blue PSM-16GT rig became operational in the late evening, and a night-shift crew left from the side of their beds to pick up work and hopefully new cores, restarting from 465.4 m depth.

    After loss of circulation and sudden stop of rods in the morning, the drilling could continue and went beyond 450 metre depth. The evening has brought full-house attendance at the local town hall meeting, in the cinema/theatre room, with 1.5 hours of presentations followed by a Q&A session.

    Another drill bit got worn down and required changing, see the very clear photo comparing the old and new bits. Changeover takes quite some time at 438.8 m depth. We hope the new bit will last at least as long as the previous ones.

    After 7 weeks of drilling core box number 100


    After 7 weeks of drilling, core-box number 100 was filled with cores, and the hole reached 429.5 m depth. Large leucocratic layers were observable on most cores. The site is now fully restored after yesterday's storm. A public event in the village Ornavasso that is hosting the drill site will take place Friday evening.

    Soon after breaking the 400-metre-depth line this morning, wind gusts attacked the drillsite and overturned every tent and gazebo, dismantled the fences and more. Thanks to a major effort of the on-site team, everything was reconstructed by the evening. In the meanwhile the drillers have produced at least 12 metres of fresh core, quality-wise similar to yesterday.

    The week-end has seen the arrival of the microbiology microscope, verified by looking at the tracer. The hunt for microbial activity traces can start for good! Today coring is back on track, with a beautiful, straight, continuous 3-m-long HQ core extracted from 390 m depth, sampling a sharp metapelite–amphibolite contact.

    Binary file (standard input) matches Today's picture, ""The Lost Catcher and the Old Bit"", turned out to be a shorter story than ""The Old Man and the Sea"", but for DIVE it was still an award-winning event as drilling could then continue and reach 372.4 m depth.

    Not every day brings good surprises. Today the core catcher broke (see on the left of the photo). Most of it could be pulled out, but a piece remained at the bottom of the hole (similar to what is highlighted with the arrow on the right). Hopefully it will be still attached to the piece of core lost during the recovery.

    We past 300 m depth with a borehole deviation


    We past 300 m depth with a borehole deviation of less than 1.5° from vertical, which is well within the wished tolerance. After a logging session over the weekend, we resumed drilling and changed from PQ to HQ diameter. Using HQ, we collected 15 m of cores in a single day shift. The foliation we observe now is at an angle from vertical.

    Today the 300 m line was passed still using PQ. This will allow the broadband seismometer to sit there comfortable in the future. During the weekend logging will now take place before we resume drilling using a smaller, HQ, diameter. -we'll know better after this week-end's logging where we are structurally, indeed in the recent days many cores showed axis parallel foliation, which we don't want to see for too long -after the logging, drilling will continue with HQ and hopefully speed up a bit -there have been interesting mineralogical news, graphite, some sulphides, and very nice ductile deformation features

    No drilling shifts on Saturday night or Sunday but we have plotted the first 180m of Magnetic Susceptibility data recorded at 10cm intervals along the core. After (core-diameter) volumetric corrections we can clearly see some lithologic changes and localised anomalies.

    A bigger rig has arrived. Il piccolo carro di perforazione has left site and il medio carro di perforazione has arrived. A new diamond drill bit will be put the test in the hope of getting a better RoP in this very hard rock, and we also cased off the upper section of the borehole 3m during the change over. Fingers crossed no more obstacles ahead.

    Another couple of big days for the DIVErs Only


    Another couple of big days for the DIVErs. Only a half day of drilling on Saturday, but we are now at 20.7m with over 95% core recovery from 0.0m. The core is amazingly competent with near 100 % RQD. Going slow with the RoP to ensure absolute verticality for the future borehole seismometer c.a. 300m. ICDP Scientists Katja Heeschen and Thomas Wiersberg are on site helping with mDIS, core scanning, and setting up the online gas monitoring (OLGA) system. ISTere Grenoble are ready to go with the OLGA support. The science offices are still evolving and we expect to have lots more core images, and analysis in the next days.
