Science / Tides and Currents / Radiational Tide: Periodic variations in sea level primarily related to meteorological changes such as the semi daily (solar) cycle in barometric pressure, daily (solar) land and sea breezes, and seasonal (annual) changes in temperature. Other changes in sea level due to meteorological changes that are random in phase are not considered radiational tides.
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
