Floating island La Rota in Posta Fibreno lake, Italy. Natural floating islands are composed of vegetation growing on a buoyant mat of plant roots or other organic detritus. In aquatic regions of Northwestern Europe, several hundred hectares or a couple thousand acres of floating meadows (German Schwingrasen, Dutch trilveen) have been preserved, which are partly used as agricultural land ...
The flying island of Laputa from Gulliver's Travels. (Illustrated 1795.) In science fiction and fantasy, floating cities and islands are a common trope, ranging from cities and islands that float on water to ones that float in the atmosphere of a planet by purported scientific technologies or by magical means.
Island hopping is the crossing of an ocean by a series of shorter journeys between islands, as opposed to a single journey directly to the destination. Often this occurs via large rafts of floating vegetation such as are sometimes seen floating down major rivers in the tropics and washing out to sea, occasionally with animals trapped on them. [ 1 ]
The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment. This sun-drenched habitat can be defined as roughly one metre in depth, as nearly half of UV-B is attenuated within this first meter. [ 2 ]
Profiling floats can have more than one sensor of the same type on it. A sensor on top of the float will collect data better than one on the bottom if the float is moving vertically through the water column, and a sensor on the bottom will collect data better if the float is descending.
Polynesian navigators thus employed a wide range of techniques including the use of the stars, the movement of ocean currents and wave patterns, the patterns of bioluminescence that indicated the direction in which islands were located, the air and sea interference patterns caused by islands and atolls, the flight of birds, the winds and the ...
In this dynamic way, the current itself can, over time, become a moving habitat for multiple types of marine life. Ocean currents can be generated by differences in the density of the water. How dense water is depends on how saline or warm it is. If water contains differences in salt content or temperature, then the different densities will ...
