The R/V Lance is an old sealing vessel that was converted by the Norwegian Polar Institute to support oceanographic research. Its design requires moorings to be deployed off the ship’s…

Researchers from WHOI and crew from the Canadian icebreaker Louis S. St. Laurent prepare to deploy an ice-tethered micro-mooring (ITM) on a large ice floe in the Canada Basin in…

Icebergs were a common sight around the British icebreaker James Clark Ross during a 30-day summer research cruise along Greenland’s east coast to the high-Arctic island of Spitsbergen. The expedtion, led…

While Hurricane Sandy was lashing the East Coast, a low-pressure system was making life difficult for the scientists and crew of the U.S. Coast Guard Cutter Healy. The team was…

In August 2012, the US Coast Guard Cutter Healy sailed through unusually light sea ice across Hanna Shoal in the norhtern Chukchi Sea. The cruise was the first in the…

The U.S. Coast Guard Cutter Healy plows a path through ice in the Beaufort Sea. Evidence of Earth’s changing climate is especially visible in the Arctic, making it an important area…

A team of researchers sample ice and snow from an ice floe in the Canada Basin, an area northwest of the Canadian coast, during a 2008 expedition to measure carbon…
