What a day! Today we entered Antarctic Sound, also known as Iceberg Alley. And what a place it is! Gigantic table icebergs float everywhere, and on smaller 'bergs Adelie penguins perch in the dozens. I've seen one seal as well and this morning a whale rose near the ship. The ice is getting thicker as we enter the Weddell Sea and the ship now shakes occasionally with the impact.
Less dramatic happenings include a few games of ping pong as the ship rocked and rolled through the end of the Drake Passage, and I tried out some of the exercise equipment earlier this morning.
! Much depends on improving visibility, so the whole ship has our collective fingers crossed.
