Lowest Astronomical Tide

Science / Tides and Currents / Lowest Astronomical Tide: As defined by the International Hydrographic Organization, the lowest tide level that can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions.

Secondary Control Tide Station

Science / Tides and Currents / Secondary Control Tide Station: A tide station at which continuous observations have been made over a minimum period of 1 year but less than 19 years. The series is reduced by comparison with simultaneous observations from a primary MORE

Reduction Of Tides

Science / Tides and Currents / Reduction Of Tides: A processing of observed tide or tidal current data to obtain mean values for tidal or tidal current constants. MORE

Red Tides

Science / Biology / Red Tides: Phenomenon associated with population explosions (blooms) of certain types of dinoflagellates; red structures inside the dinoflagellates cause the water to have a reddish color. MORE

Red Tide (Water)

Science / Tides and Currents / Red Tide (Water): The term applied to toxic algal blooms caused by several genera of din flagellates (Gymnodinium and Gonyaulax) which turn the sea red and are frequently associated with a deterioration in water qualit MORE

Sequence Of Tide

Science / Tides and Currents / Sequence Of Tide: The order in which the four tides of a day occur, with special reference as to whether the higher high water immediately precedes or follows the lower low water. MORE

Single Nucleotide Polymorphism (SNP)

Science / Genetics / Single Nucleotide Polymorphism (SNP): Dna sequence variations that occur when a single nucleotide (a, t, c, or g) in the genome sequence is altered. MORE
