Icebergs, scientists are discovering, play host to all kinds of life —
everything from tiny plantlike organisms called phytoplankton to
enormous whales. This world of extreme cold and isolation bustles with
surprising amounts of activity.
Identifying how and why animals
choose to make their homes in and around icebergs hasn’t proven an easy
task for scientists. Icebergs stretch to towering heights and even more
dizzying depths. To study them underwater, scientists may sink
