How to use in-sentence of “sea ice”:
+ Cook’s observations were based on either a misidentification of sea ice or an outright fabrication.
+ The expedition’s ship, “Deutschland”, had become trapped in heavy sea ice while attempting to establish a shore base at Vahsel Bay.
+ However when wind blows sea ice around, this mixing is much deeper, and the strength can change.
+ Because sea ice is made of frozen seawater, it is salty.
+ A phenomenon called Arctic sea ice decline can be shown on the islands: In the 20th century, the islands were a portion of Eurasia which was always covered by ice.
+ In the overall mass balance, the volume of sea ice depends on the thickness of the ice as well as the area covered.
+ It is also relatively easy to pull apart a single piece of sea ice by pulling opposite edges in opposite directions.
+ This makes it impossible to keep track of all the sea ice at once and see how its changing.
Example sentences of “sea ice”:
+ It also means that the area of sea ice is decreasing.
+ In particular, coastal residents of the Arctic travel over the sea ice and use it to hunt animals.
+ It also means that the area of sea ice is decreasing.
+ In particular, coastal residents of the Arctic travel over the sea ice and use it to hunt animals.
+ Others make pictures of the sea ice using microwave energy that can go through clouds.
+ However they are still relatively unsure how thick the sea ice is, in part because it is unclear how much snow is resting on the ice at any one time.
+ The trends from 1979 to 2002 have been a statistically significant Arctic sea ice decrease of 2.5%±0.9% per decade during those 23 years.
+ Although it’s not smooth like a mirror, sea ice is very shiny.
+ Measuring the amount of snow that exists on sea ice is difficult, European scientists are currently designing a new satellite called CRISTAL to help study it.
+ The sea ice cycle is also an important source of dense “bottom water”.
+ When warm air moves up into the Arctic, it can cause the sea ice to melt and break up.
+ Because the ice is salty, sea ice is heavier, less transparent and easier to break than ice that isn’t salty.
+ Going to the sea ice is difficult and sometimes dangerous.
+ One reason for this is because sea ice formation and melting is very sensitive to temperature changes.
+ When two pieces of sea ice squash up against each other, they can crumple up and break to form a ‘ridge’ at the part where they touch.
+ These temperature rises mean that the sea ice begins growing later in the year, and begins melting earlier in the year.
+ As more and more of the sea ice 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.
+ This behaviour is dominated by the fact that sea ice is not entirely solid – instead it contains lots of tiny pockets of salt water.
+ A computer-based, time-resolved calculation of sea ice volume, fitted to various measurements, revealed that monitoring the ice volume is much more important for evaluating sea ice loss than pure area considerations.Zhang, Jinlun and D.A.
+ As well as the regular seasonal cycle there has been an underlying trend of declining sea ice in the Arctic in recent decades.
+ Because sea ice has air bubbles and saltwater pockets inside it, it is much harder to see through than non-salty, clear ice.
+ When the air is warmer, sea ice grows slower and melts faster.
