Todays Highlights

We continued our voyage towards Aberdeen. People have been tidying labs and work areas, correcting data entries and continued preliminary analyses. The plankton people have worked their way through another few tapes (and hours) of ROV-observations to look for jelly-plankton.

Weather has been pleasant, allowing us to enjoy the view of the outer Hebrides and mainland northern Scotland. We passed rather close to the now uninhabited isolated island St. Kilda. During the night we entered the North Sea through the Pentland Firth.

The afternoon series of seminars was continued with four more presentations of preliminary findings:

 

  • Lars Stemman summarised underwater video profiler (UVP) observations and showed good correspondence between results from Leg 1 and Leg 2, and a seemingly strong pattern tied to watermass characteristics.
  • Nicola (Nikki) King showed results from the ROBIO lander observations, illustrated by lots of crisp images of scavenging fish coming to feed on the bait. Clear depth-related patterns were found in the species assemblage being attracted.
  • Franz Uiblein and others provided the first overview of demersal fish findings. The species list is steadily growing, and also the ROV observations are promising.
