Actvity Summary: Where do Antarctic icebergs come from and how do they form? What can scientists learn by studying the rocks and mud icebergs drop as they melt?

Inspired by Expedition 382, Iceberg Alley, Iceberg of Antarctica follows an iceberg’s formation and journey from snowfall, to ice stream grinding across the continent, to the iceberg’s calving, drifting, and eventual melting in the ocean. Through lyrical prose and watercolor illustrations, it explores what we can learn about melting of the Antarctic Ice Sheet from the debris icebergs leave behind.

Author and Illustrator, Marlo Garnsworthy, sailed as the Onboard Outreach Officer on Expedition 382: Iceberg Alley and Subantarctic Ice and Ocean Dynamics.  Read Marlo’s blogs and view artwork from the expedition.
