Diurnal variation in hydrological variables and dissolved inorganic nutrients such as PO inf4 sup3− -P, N O inf2 sup− -N, NO inf3 sup− -N and NH inf4 sup+ -N were studied in three interconnected biotopes including freshwater, marine and mangrove brackish water of the Kakinada coastal zone, Andhra Pradesh. Samples were collected at intervals of 3 hours, for a period of 24 hours. In the marine environment salinity varied from 26‰ to 32‰ whereas in the mangrove waters it fluctuated from 12‰ to 20… CONTINUE READING
