The Antarctic Peninsula is home to some of the most spectacular natural artwork on the planet. Here, you'll find ninety-three percent of the world's mass of icebergs, an ever-changing icescape of "growlers" to bergy bits and even ice islands. Growlers are the smallest icebergs, less than 6.6 feet across, with less than 3.3 of their mass showing above water. Bergy bits – that's their real, official name – are the next size class, spanning 6.6 feet to 15 feet in size. These smaller chunks of floating glacier ice are often the result of larger icebergs breaking down.
