Figure F4. CORK umbilical tubing samples from Expedition 301. Pen for scale. The Hole 1026B umbilical comprised surplus material from Leg 205. The Hole U1301A umbilical comprised surplus material from Leg 196. The Hole U1301B umbilical (and that intended for use in Hole 1027C) were created for Expedition 301. The main tubing bundle (yellow) contains packer inflation, pressure monitoring, and fluid sampling lines. All of these umbilicals are made of stainless steel encased in a plastic housing. The separate tube (gray) contains a more chemically inert Tefzel line, surrounded by a metal braid and covered with plastic, used for microbiological sampling in the lower interval in Hole U1301B.
