Petermania (IV): Red Menace!

Better yet: the Terra satellite's false-colour band 3-6-7 imagery is just the ticket! Click to enlarge; one pixel one the image represents about 250 metres.

Terra's 3-6-7 imagery combines visual and infrared wavelengths to help tease out details in earth imaging that aren't visible in normal light alone. Usually used to identify features such as burn scars in vegetated areas, it also renders ice as bright red, distinguishing numerous false-red icebergs from yellow-white puffy cloud tops.

Not only is the main Petermann ice island conspicuous, the smaller ice islands and icebergs in the Strait of Belle Island and off the coasts of Labrador and Newfoundland pop out at you in the enlarged image.
