Pelage

With the help of equiUbrium constants, the extent of adsorption can be predicted as a function of pH and solution variables (7,25,43). Based on this model, the partitioning of metal ions and of ligands (organic and inorganic anions between water and pelagic clays and suspended particles) can be explained.

Fig. A.3. Light meter used by the author (Model 8020, Pelagic Electronics). For total light measurements, the signals are integrated with capacitors. Milliammeter reading is automatically reset at full-scale position, and the number of resets is digitally indicated below the meter. The box at the right contains a photomultiplier and sample compartment.

The sediment surface separates a mixture of solid sediment and interstitial water from the overlying water. Growth of the sediment results from accumulation of solid particles and inclusion of water in the pore space between the particles. The rates of sediment deposition vary from a few millimeters per 1000 years in the pelagic ocean up to centimeters per year in lakes and coastal areas. The resulting flux density of solid particles to the sediment surface is normally in the range 0.006 to 6 kg/m per year (Lerman, 1979). The corresponding flux density of materials dissolved in the trapped water is 10 to 10 kg/m per year. Chemical species may also be transported across the sediment surface by other transport processes. The main processes are (Lerman, 1979) ...

Zooplankton are small, often microscopic crustaceans that live in the water colunm. They are widely distributed, common, and important in pelagic food webs. Zooplankton are eaten by marty fish and by early life stages of some fish that become piscivorous as juverriles or adrrlts. Zooplankton are not eaten by httmans but are an appropriate and relevant candidate indicator because of their importance in the trophic transfer of MeHg to fish. Sampling would not significantly affect populations or assemblages of zooplankton, even in small lakes.
