摘要: Abstract Nutrient data from Great Bay Estuary, New Hampshire, were analyzed using a conservative mixing model to assess nutrient distribution and variability with time, determine budget. Analytical precision was estimated as the magnitude of short term (5 min intervals) environmental variability. Finally, monthly this phosphate budget calculated for one year period. In well mixed waters, short-term sampling showed that processes can mix estuarine waters so due small-scale turbulence or imperfect is less than analytical However, when system not then be distinct may attributed some other process processes. The used predict apparent average river concentration based on zero salinity intercept near mouth estuary. Predicted concentrations agreed measured during winter early spring, but much higher summer fall. Total flux dissolved into estuary 70.7 × 105 moles/yr 1976 78% input municipal sewage rest rivers (13%), sediment (7%) rainfall (2%). Only about 12% exported coastal while apparently remained trapped in sediments.
