A Tab in the Ocean is the second album from German-based English progressive rock band Nektar. English heavy metal band Iron Maiden covered the song "King of Twilight", also mixing in parts of "Crying in the Dark" creating somewhat of a medley, and released as a b-side to the 1984 single " Aces High ".
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
A length of pipe suspended from the ship down to the bottom of the sea might have been as long as 6,243 m (20,483 feet). The maximum depth penetrated through the ocean bottom could have been as great as 1,299 m (4,262 feet). To replace the bit, the drill string must be raised, a new bit attached, and the string remade down to the bottom.
When the age of the ocean crust as determined by magnetic anomalies or drill hole samples was compared to the ocean depth it was observed that depth and age are directly related in a seafloor depth age relationship. [25] This relationship was explained by the cooling and contracting of an oceanic plate as it spreads away from a ridge crest. [26]
When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. [1] The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming the familiar sharp ...
The first documented observations of an Ekman-like spiral in the ocean were made in the Arctic Ocean from a drifting ice floe in 1958. [10] More recent observations include (not an exhaustive list): The 1980 mixed layer experiment [11] Within the Sargasso Sea during the 1982 Long Term Upper Ocean Study [12]
GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...
