We dock in Pleneau Bay, Antaractica, an iceberg graveyard between a ring of mountains, and gear up for our morning excursion: Standup Paddleboarding! We were among a handful on the Quark expedition ship to SUP, partly because there are limited spots and partly because it’s borderline insane. Standing on a shaky board over hypothermia-inducing water and paddling around icebergs that could roll and tidal wave…this could go badly. But instead, it was epic. The sheltered bay was perfectly still, reflecting every neon-blue iceberg like a mirror. We paddled through brash ice in a state of heightened adrenaline and wonder.
