Did you realise that we have a big hole in the bottom of our boat? Its hard to imagine that a boat can float with a hole in its bottom, but there has to be somewhere for the drill string to pass from the derrick to the sea floor. This big hole is called the moon pool and on rare occasions like the other day, we get to see the moon pool completely open.
This afternoon around lunch time we arrived at the last drilling site of Expedition 339 (Site U1391), located on the Portuguese SW Margin.
