1. Sea ice

   Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice, which has an even lower density). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. 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 ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs.

1. Sea ice

   Sea ice is frozen seawater. Because ice is less dense than its melt, sea ice floats. Sea ice covers about 7% of the Earth’s surface, or about 12% of the world’s oceans. In the North, it is found in the Arctic Ocean, in areas just below it and in other cold oceans, seas and gulfs; in the Antarctic, it occurs in various areas around Antarctica. 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 ecosystems.

Examples of sea ice in a Sentence

1. Peter Fretwell:

   It shows two things, firstly that when faced with long-term poor conditions emperors will move, rather than try to tough it out at the old location, this gives them some resilience in the face of future change, secondly, it shows how little we know about what drives sea ice dynamics, which is worrying for all species that require that habitat.

2. Andrew Shepherd:

   Growth of Antarctic sea ice over the past few decades had been a relief, because it offset some of the rapid losses in the Arctic, now that sea ice is retreating in both hemispheres we should be concerned about our planet's temperature because it means less of the sun's heat is reflected back into space.

3. Donna James:

   These communities rely on walrus to fill their freezers throughout the year, they were not able to hunt the way they normally do because of changing sea ice and winds.

4. Marilyn Raphael:

   That kind of drop is pretty much unprecedented in the record, antarctic sea ice does vary from year to year, but that was a bigger variation than what normally happens.

5. Gemma Clucas:

   The distances from the open ocean, where the penguins feed, to the stable sea ice, where they breed, was probably too far, the three populations that did manage to survive may have done so by breeding near to polynyas — areas of ocean that are kept free of sea ice by wind and currents.
