From September to November 1967, Northwind was beset by ice 450 miles (720 km) north-northwest of Point Barrow, Alaska. She was freed by CCGS John A. Macdonald, USCGC Glacier, and USCGC Staten Island. [1] During this cruise Northwind made the northernmost penetration into Arctic pack ice by any surface vessel in history at the time.
Younger ice (first-year ice) is shown in darker shades, while older ice (four-year or older) is shown in white. This visual shows the Arctic sea ice change and the corresponding absorbed solar radiation change during June, July, and August from 2000 through 2014. The Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The ...
Similarly, ships can get stuck between drift ice floes. The two major ice packs are the Arctic ice pack and the Antarctic ice pack. The most important areas of pack ice are the polar ice packs formed from seawater in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs ...
The sea-ice observations covered the broad range from the physical and mechanical characteristics of Arctic sea ice, to its morphology, optical properties and mass balance. [23] The emphasis was on characterising snow cover and ice cover, and on arriving at a better understanding of the processes that determine their properties.
[1] [2] [3] Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology , including the ocean's ...
A pressure ridge, when consisting of ice in an oceanic or coastal environment, is a linear pile-up of sea ice fragments formed in pack ice by accumulation in the convergence between floes. Such a pressure ridge develops in an ice cover as a result of a stress regime established within the plane of the ice.

As ice melts, the liquid water collects in depressions on the surface and deepens them, forming these melt ponds in the Arctic. These fresh water ponds are separated from the salty sea below and around it, until breaks in the ice merge the two. Melt ponds are pools of open water that form on sea ice in the
