After 11 hours of transit, we are now at the location of the RSN Midplate node, at the start of our first cable segment (Segment 6). Water depth is about 2,850m. The seabed is flat and covered with a thick layer of sediment. This segment is about 210km long and will be surface laid onto the seabed across the Juan de Fuca Ridge in the direction of Axial Seamount. This task will take a few days. First comes the anchor and ground rope (scrap cable) and then the RSN cable comes out of the vessel tank through the Linear Cable Engine (LCE). Excitement is building onboard for the OL/UW team; for everybody else it seems like just another day at work.
