Some days aren't as good as others. It began with printing problems in the DIS - a minor thing, but it upset the whole workflow and, thus, produced stress. If drilling goes well, then there is no time to fix things. And just as we got used to it, the new p-wave transducer of the MSCL got punctured. But last time this happened, we also got spares from an old core logger. Yesterday, we had exchanged some mechanical parts. Today we took also the transducer. We can only hope that it will last. Once we got help with the DIS (thank you, Ronald) and had fixed the core logger, the drill bit was worn down and drilling stopped at 10 a.m. (after 30 m of top quality core since midnight!). The bit is now changed, but again, as last time, the drillers have to ream up the hole before they can continue with core drilling. Maybe there's something wrong with the material? Presently, (18.00) we are waitung for the core drilling to continue.
