It is easily a hundred feet tall, solid and old, its glacial ice so compacted that the air pockets has been squeezed out, making it ever more blue. • Ice is everywhere here. The 74-foot Pelagic Australis’s deck is sheathed in a thin layer of it. The boat glances off sizable pieces broken away from the 700,000-square-mile pack that surrounds Antarctica each spring. While I’ve been here several times before, a few of my teammates are seeing these big bergs for the first time.
