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
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
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
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
Science / Tides and Currents / Solar Tide: (1) The part of the tide that is due to the tide-producing force of the Sun. (2) The observed tide in areas where the solar tide is dominant. This condition provides for phase repetition at about the MORE
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
