NODAL. Interpreted language implemented on Norsk Data's NORD-10 computers. Used by CERN and DESY high energy physics labs to control their accelerator hardware, PADAC and SEDAC. Included trackball input, graphics. For the former stadium in Houghton, Michigan, see Dee Stadium. An amphidromic point is a point of zero amplitude of one harmonic constituent of the tide. The tidal range (the amplitude, or height difference between high tide and low tide) for that harmonic constituent increases with distance from this point. These points are sometimes called tidal nodes. Tsunami (sesmic sea wave). Definition. Long period sea wave produced by a submarine earthquake, volcanic eruption, sediment slide, or seafloor faulting. It may travel across the ocean for thousands of miles unnoticed from its point of origin and build up to great heights over shallow water the shore. Type of wave in whcih the surface of the water oscillates vertically between fixed points called nodes, without progression; the points of mximum vertical rise and fall are called antinodes. Term. nodes. Definition. point of least or zero vertical motion in a standing wave. Seiche 1 Seiche A short-period oscillation in an enclosed or semien-closed body of water, analogous to the free oscilla-tion of water in a dish. The initial displacement ofwater from a level surface can arise from a variety ofcauses, and the restoring force is gravity, which al-ways tends to maintain a level surface. Definition. long-period gravity wave that has it's origin in the tide-producing force and is observed as the rise and fall of the tide. A tide waves is about 12 hours and 45 minutes. The term amphidromic point derives from the Greek words amphi (around) and dromos (running), referring to the rotary tides running around them. The M 2 tidal constituent, the amplitude indicated by color. The white lines are cotidal lines spaced at phase intervals of 30° (a bit over 1 hr). Term. bioluminescence. Definition. production of light by liviing organisms as a result of a chemical reaction either within certain cells or organs or outside the cells in some form of excretion.
A point of zero amplitude of one harmonic constituent of the tide.
