pH Fluctuation in an Intertidal Beach in Bermuda
Gnaiger E, Gluth G, Wieser W. 1978. pH Fluctuation in an Intertidal Beach in Bermuda. Limnology and Oceanography. 23(5):851-857
Unusually high pH values up to 9.6 measured during low tide in a calcareous sandy beach were correlated with high in situ temperatures. Daily fluctuations of up to 1.5 pH units are limited to the topmost layer of sediment. Light, by controlling photosynthesis, is the causal factor in determining high pH at the surface; subsurface sediments do not respond to experimental light changes. Indications of such fluctuations are lacking in the literature. These fluctuations could influence community respiration.
