Ice Core Secrets

Background
What does ice tell polar scientists? Guide students to understand the types and properties of ice by dispelling the misconception that "ice is ice."

Why do scientists take ice cores and what do they learn from them?

Go to ../../tea_meetteachers.html ("Meet the Teachers" link) for Sandra Kolb's, Marjorie Porter's and Sandra Shutey's journals and photos of ice core fieldwork in sea, lake and glacial ice, respectively.

Photos:

John Gagnon and Chris Meadus using an ice corer on an Arctic ice floe in Davis Strait.

Removing the ice core from the corer.

Measuring the ice core. Measurements are taken in centimeters.

Drilling holes every 10 cm for placing the temperature probe and taking temperature readings.

Slicing the ice core into 10 cm sections.

Weighing each 10 cm section for documenting the ice weight.

The rectangular slice shows a vertical thin section of Arctic sea ice from a depth of about 85 cm. It shows the columnar nature of sea ice. The semi-circle slice shows a horizontal thin section of Arctic sea ice from a depth of 85 cm.
