Iceberg Versus Island in the South Atlantic Ocean

Most people picture icebergs like big floating boulders in the ocean. Maybe they might be as large as a house. The famous iceberg was big enough to sink the Titanic in 1912. However, most people don't really consider icebergs too deeply, beyond some memes about having more beneath the water than above it. Yet, icebergs, especially in the southern oceans, are becoming an increasing threat as the Antarctic ice sheets break apart thanks to climate change.
