Black ice
Black ice is largely air-bubble-free, very compact and relatively stable ice. It appears very transparent and therefore appears in the color of its subsurface, often wet asphalt or dark water floors. Black ice forms when the surface freezes on standing or slowly flowing water. In addition, it can also form on solid surfaces through the accumulation of supercooled droplets of mist (see clear ice ).
Since it is difficult to see, it poses a danger in the form of icy winter conditions in road traffic and at sea.
Black ice in seafaring
Black ice poses a threat to trawlers who use trawls to fish in cold waters. A combination of sub-freezing air temperatures and fog or drizzle creates thick layers of black ice very quickly . With ice on the superstructure of a ship , the ship can become top heavy. This can capsize in heavy seas.
