With calm seas and bright weather, we have all been taking advantage of good conditions to carry out some iceberg and penguin spotting in our spare moments on board. The shapes and colours of the different icebergs are amazing: it’s a real eye opener to see how varied they can be! From black to green to bright white, which shines yellow and peach in the sunset, these natural sculptures are so photogenic!
Back in the lab, the multibeam survey is still underway and seismics were deployed to look at the structure of the seafloor. With the seismic array on board, the geophysicists can look down to 1 km into the seafloor to look for sediments and hard rock, or basement. This shows them where they should dredge in order to get in situ samples of rocks that erupted as the Scotia Sea formed millions of years ago. The rest of us are busy with more day-to-day activities.
