Tide Reducers

Science / Tides and Currents / Tide Reducers: Height corrections for reducing soundings to chart datum (MLLW). A tide reducer represents the height of the water level at a given place and time relative to chart datum. Tide reducers are obtained from one or more tide stations within or nearby the survey area. Often, due to differing tidal characteristics over the survey area, the tide reducers obtained directly from a tide station must be corrected to adjust for time and range of tide differences in the various zones of the hydrographic survey area. See tidal zoning.

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

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
