harmonic analysis of tides
H
habitat the characteristic space occupied by an individual, a population, or a
species. Habitats in the sea are diverse and include parts of such environments as estuaries, tidal flats, intertidal rocky shores, oceanic sea surfaces,
deep-sea bottoms, etc. Within such parts of the sea most species occupy only
specific zones, e.g., only sandy tidal flats below mean tide level in the tropics.
hadal zone ---7zonation.
haemocyanin ---7hemocyanin.
haemoglobin ---7hemoglobin.
half-life (11/2) time in which the amount of a radionuclide decays to half its initial
value, a constant for a particular nuclide. ---7radioisotopes.
half saturation constant ---7Michaelis-Menten kinetics.
halocline layer in which the salinity changes rapidly with depth. ---7stratification.
halophilic (halophile) preferring or tolerating high salinities.
halophyte plant species that can tolerate a high salt concentration in its environment. Generally said of plants growing close to the seashore or in salt
marshes.
Haptophyta ---7Prymnesiophyta.
Hardy Plankton Recorder ---7Continuous Plankton Recorder.
harmonicanalysis oftides a method for splitting up the actual tide in its partial tides.
As the periods of these components are known from astronomical considerations, the tide for a given location can be considered to consist of a combination of these components, be it with unknown amplitude and unknown
phase with respect to the tide-generating potential. For a registration of sufficient length one may determine amplitude and phase by means of mathematical procedures. For many ports these phases and amplitudes have been
established, and subsequently they can be used for tidal prediction at any
