+ The expedition’s ship, “Deutschland”, had become trapped in heavy sea ice<\/strong> while attempting to establish a shore base at Vahsel Bay.\n<\/p>\n <\/p>\n + However when wind blows sea ice<\/strong> around, this mixing is much deeper, and the strength can change.\n<\/p>\n <\/p>\n + Because sea ice<\/strong> is made of frozen seawater, it is salty.\n<\/p>\n <\/p>\n + A phenomenon called Arctic sea ice<\/strong> decline can be shown on the islands: In the 20th century, the islands were a portion of Eurasia which was always covered by ice.\n<\/p>\n <\/p>\n + In the overall mass balance, the volume of sea ice<\/strong> depends on the thickness of the ice as well as the area covered.\n<\/p>\n <\/p>\n + It is also relatively easy to pull apart a single piece of sea ice<\/strong> by pulling opposite edges in opposite directions.\n<\/p>\n <\/p>\n + This makes it impossible to keep track of all the sea ice<\/strong> at once and see how its changing.\n<\/p>\n + It also means that the area of sea ice<\/strong> is decreasing.\n<\/p>\n <\/p>\n + In particular, coastal residents of the Arctic travel over the sea ice<\/strong> and use it to hunt animals.\n<\/p>\n <\/p>\n + Others make pictures of the sea ice<\/strong> using microwave energy that can go through clouds.\n<\/p>\n <\/p>\n + However they are still relatively unsure how thick the sea ice<\/strong> is, in part because it is unclear how much snow is resting on the ice at any one time.\n<\/p>\n <\/p>\n + The trends from 1979 to 2002 have been a statistically significant Arctic sea ice<\/strong> decrease of 2.5%\u00b10.9% per decade during those 23 years.\n<\/p>\n <\/p>\n + Although it’s not smooth like a mirror, sea ice<\/strong> is very shiny.\n<\/p>\n <\/p>\n + Measuring the amount of snow that exists on sea ice<\/strong> is difficult, European scientists are currently designing a new satellite called CRISTAL to help study it.\n<\/p>\n <\/p>\n + The sea ice<\/strong> cycle is also an important source of dense “bottom water”.\n<\/p>\n <\/p>\n + When warm air moves up into the Arctic, it can cause the sea ice<\/strong> to melt and break up.\n<\/p>\n <\/p>\n + Because the ice is salty, sea ice<\/strong> is heavier, less transparent and easier to break than ice that isn’t salty.\n<\/p>\n <\/p>\n + Going to the sea ice<\/strong> is difficult and sometimes dangerous.\n<\/p>\n <\/p>\n + One reason for this is because sea ice<\/strong> formation and melting is very sensitive to temperature changes.\n<\/p>\n <\/p>\n + When two pieces of sea ice<\/strong> squash up against each other, they can crumple up and break to form a ‘ridge’ at the part where they touch.\n<\/p>\n <\/p>\n + These temperature rises mean that the sea ice<\/strong> begins growing later in the year, and begins melting earlier in the year.\n<\/p>\n <\/p>\n + As more and more of the sea ice<\/strong><\/strong> is thinner first-year ice the greater effect storms have on its stability with turbulence resulting from major extratropical cyclones resulting in extensive fractures of sea ice<\/strong><\/strong>.\n<\/p>\n <\/p>\n![\"sea](\"https:\/\/englishteststore.net\/blog\/wp-content\/uploads\/2021\/09\/sea-ice-example-sentences.jpg\" "\\"sea")
