- Captain Robert Falcon Scott CVO (6 June 1868 – c. 29 March 1912) was a British Royal Navy officer and explorer who led two expeditions to the Antarctic regions: the Discovery expedition of 1901–04 and the Terra Nova expedition of 1910–13.
- Sea ice (Wikipedia)
Sea ice forms as seawater freezes. Because ice is less dense than liquid water, it floats on the ocean’s surface (just like fresh water ice). 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 naturally undergo significant yearly cycling, reaching their greatest surface extent in winter and retreating in summer.
