Very early in the morning problems with sandy layers in the sediment occurred and the hydraulic system of the drillrig failed to work. Thus the last shot was recovered only hours later at twilight when the hydraulic problem was fixed. Hole D had to be abandoned at 98 m sediment depth. Smear slide analyses in the laboratory demonstrated that we were back to diatomaceous lake mud! It was then decided to continue with downhole logging. Everything was set up when the wind picked up with force and work had to be stopped for security reasons. The strong westerly winds with gusts over 100 km/h caused the drill pipe to break and the anchors to fail. The platform drifted towards the eastern shore line. 300 m off the shore anchors started to hold again and the drifting ended. However, one anchor line broke and we lost this anchor. While the lake water was virtually boiling, two drillers and two scientists were trapped on the platform for the entire day with water splashing over the platform. The catamaran was not able to pick them up until dawn.
