Neap Tides Or Tidal Currents

Science / Tides and Currents / Neap Tides Or Tidal Currents: Tides of decreased range or tidal currents of decreased speed occurring semimonthly as the result of the Moon being in quadrature. The neap range (Np) of the tide is the average range occurring at the MORE

Subordinate Tide Station

Science / Tides and Currents / Subordinate Tide Station: (1) A tide station from which a relatively short series of observations is reduced by comparison with simultaneous observations from a tide station with a relatively long series of observations. See t MORE

Solstitial Tides

Science / Tides and Currents / Solstitial Tides: Tides occurring near the times of the solstices. The tropic range may be expected to be especially large at these times. MORE

Spring Tides Or Tidal Currents

Science / Tides and Currents / Spring Tides Or Tidal Currents: Tides of increased range or tidal currents of increased speed occurring semimonthly as the result of the Moon being new or full. The spring range (Sg) of tide is the average range occurring at the tim MORE
