Cold to the Core
Photograph by Paul Nicklen
Ice cores provide a slice of life for scientists interested in Arctic organisms. Rolf Gradinger and Bodil Bluhm of the University of Alaska Fairbanks examine one such sample drilled out from the multiyear ice. Color in the core would suggest sediment and microscopic plants, but the scientists found little of either, suggesting what they expected: low food production in the summer months in high-northern region.
