It's a well-known fact that the majority of an iceberg lies below the surface -- but just as stealthily hidden are the iceberg's other fascinating qualities. Traveling the seas, teeming with life, and sometimes even making a noise called "bergie seltzer," there's so much more than meets the eye. Camille Seaman gives homage to these icy isles.
For a look at the mathematics of sea ice, check out this video from the the U.S. National Science Foundation, that explores just how porous sea ice can be.
To study ice, as well as environmental conditions, scientists (and mathematicians) often use Ice Cores. You can simulate your own ice core study in the classroom with this lesson plan from the Byrd Polar and Climate Research Center.
And for just about everything else you need to know about just about every type of ice, the Canadian government has this comprehensive database that covers everything from Sea Ice cycles to Ice Shelf mechanisms.
