Sunday 19 September Final Day! Yesterday (Sat) we came into port in the early morning to a different dock than the one we left. This dock had lots of big cranes for moving containers and fixing ships. When we arrived at the dock at least 10 ship's staff were involved in 'tieup' of the ship with these ropes as thick as your arms.
Day 11 (Thursday 16 September) Datalogging is a long and fancy word for collecting data long term via computer. Holes are drilled into the sea floor to either to collect a sediment core or place an ACORK inside and this is the perfect place to gather data from equipment that are mounted on long spear like structures.
There are two navigation systems on the ship. The 'regular' navigation works from Port to Location using two large aft mounted turbines (screws) with rudders attached. The Captain on the Bridge does the driving. Then when location is reached 12 large dynamic positioning thrusters are set down into the water almost 8 feet below the hull.
Day 10 (Wed. Sept 15) This morning I got up about 5:30 am for a run around the helipad before our typical 7:30 am start. Sometimes I run with my room-mate Amy, but today she was participating in a videoconference showing off the gumby suit (life saving bright red body suit that is hard to put on and makes one look really ridiculous).
Day 9 (Tuesday 14 September): The process of sending pipe down the 1300m to the sea floor, whether to drill or core, or place instruments that measure pressure & temperature is called "tripping the pipe". The pipe is made from steel but amazingly when the rig pulls up the pipe 'string' the steel pipe 'bends' a little bit which is a wicked sight to see!
Day 8 (Monday 13 Sept) The Joides runs so well because of the fabulous staff on the Bridge, in Engineering, on the Rig Floor, in the Galley, in IT, and in the Science Labs. Everyone is patient, supportive, curious, hardworking, and interesting! The ship is like a small city with generators, water desalination plant, waste management, and other infrastructure.
So you probably know that as you go deeper into the ocean the pressure increases from the weight of all the water above you. So we did an experiment. We took styrofoam coffee cups and decorated them before sending them 1300 m (4265 feet) below sea level. When we brought them back up they had shrunk!
