Leg 1, Day 20.
Another calm but cool day on the Akademik Tryoshnikov found us steaming south-southeast on the great circle route towards Hobart. The protracted CTD station was delayed due to relatively shallow water, so we ran transects from 5-13h00. Birds were fairly monotonous, with mainly Antarctic Prions circling around the ship. The last Fulmar Prion was seen at 9h38 just after 80°E. On station, few birds were present, but the calm conditions resulted in several cetaceans being seen, including a distant pod of Hourglass Dolphins.
Bull Kelps Durvillaea antarctica were quite abundant, with 44 pieces observed. At least one piece of plastic litter was seen.
