Coast Guard Cadets Kristina Kean and Ryan Gurr stand on the helipad before flying over the Beaufort Sea for ice reconnaissance.


Louis

The Louis S.-St. Laurent viewed from the cabin of the helicopter, roughly 2000 feet in the sky. From this distance, the massive ship looks like a toy boat.


Finger

The zipper-like pattern bisecting the frame shows two thin sheets of ice responding to forces pushing them together. Rather than having one sheet subduct and one form a ridge, the two sheets do what is called "finger rafting," a name derived from the finger-like pattern of their intersection.


Big finger

Finger rafting produces startling geometry. In this case, a rigid rectangle stands out amid sensuous curves and organic shapes.

Viewed from the helicopter, the sea ice appears endless.

The Louis uses a sophisticated arsenal of tools to navigate ice-covered waters and facilitate scientific research in inhospitable environments. Chief among these tools is its primary source of transportation off the ship, the helicopter. In times when navigation requires first-hand observation of conditions ahead, the helicopter carries scouts to explore the vicinity and determine efficient pathways through the ice. When not being used for ship-related exploration, the helicopter's aerial perspective provides expansive views that help scientists understand the mass movement of Arctic ice. These expeditions go by what is arguably the most action-packed term in environmental science, ice reconnaissance.

Today, helicopter pilot Jim Myra led a group of cadets and scientists on an ice reconnaissance mission. Ice expert Alice Orlich of the University of Alaska-Fairbanks was on board to document the environment and get an idea of how Beaufort Sea ice is behaving in September, when Arctic ice cover reaches its annual low.
