Science / Weather / Neap Tide: A tide of decreased range, which occurs about every two weeks when the moon is at one quarter or three-quarters full.

Flood Tide

Science / Geology / Flood Tide: A tidal current that generally moves landward and occurs during the part of the tide cycle when sea level is rising. (See neap tide for contrast.) MORE

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

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

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

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

Solar Tide

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
