We have spent the day continuing our hunt for vent plumes with the CTD probe, running survey lines across Hook Ridge. We think we are gradually homing in on the source of the signals that we are finding. Soon we should have a good target for the SHRIMP camera system, to see what is happening - and living - at the seafloor.
Our survey lines today were occasionally interrupted by icebergs straying across our path; icebergs have right of way.
