What is fast ice?
Everyone knows that James Bond likes fast cars, fast women and fast ice. Actually, no. In the latter, it is "fast" as in "Landfast". A fast ice is ice that is anchored to the mainland and remains in place instead of hovering like drift ice. Technically, the term "fast ice" is also used specifically for referring to sea ice, such as ice, which is formed in the Arctic and along the coast of Antarctica. In the first case, it is formed along the coast, because the weather cools down in the winter months, anchor into the ground and slowly develops into a large ice area that can significantly protrude far from the soil. A fast ice can be surrounded by a field of carried ice, some of which can be left from fast ice of the previous year. Sometimes it associates with anchoring ice, immersed ice that has joined the bottom of the ocean. Anchoring ice holds fast ice in place while developing, often develops fantastic underwater patterns in response to tide movement.
Many features make fast ice interesting. Although it is firmly attached to the landing, fast ice still moves with an inflow and contributes to the development of strange patterns, cracks and cracks, because the ice is not flexible enough to change the sea level. The fast LED also usually bursts from the ground in the summer months, creates ice cloaks and turns into a drifted ice. Over time, the pads will be divided into smaller pieces of ice that float in the open ocean.
Fast LED can be useful for navigation if the properties of a particular deposit of fast ice are well known. For example, robust ice can support vehicles and suction that can otherwise be used to transport goods from a boat that could not otherwise produce a harbor. It can also form temporary bridges or links between ground masses that can be used for ground transit. Fast ice deposits may also pose a danger because the ice can tear or put under the weight of an unsuspecting person or inoznles if it is sufficiently thin. In cases where fast ice has been formed above the water, ice failure may be catastrophic.
