The ones we saw were usually in groups of three or four, bounding about on ice floes or swimming together. I want to learn more about seals, now that I've seen some. The icebergs are distinctly different here also. They are dirty, not the blue and white ones of the Amundsen Sea. There are no large ice shelves in the Gerlache Straits.
Bergs calve directly off land glaciers into the water.
Gravel, rocks and sand have no time to melt off their bottoms before the glacier piece becomes a separately floating berg. The result is that icebergs look like snow plow piles melting in spring. The sun set behind the peaks of Brabant Island on our left, but long after we were in the shade the tops of the mountains on the Danco coast were lit up in pure orange-yellow alpenglow. Just before the galley closed. I ran down and grabbed a quick snack so I could get back outside to watch.
