| Popis: | Contemporary publications on various aspects of sediment traps application in marine and fresh waters are reviewed. Recommendations are given to construction and exposure of sediment traps in water column to a representative collection of settling particles (shape and size of traps, bafflers, covers, sodium chloride addition, suspending devices and free drifting traps, bactericides, swimmers influence, periphyton growth and settling material decomposition assessment, exposure duration, and bottom resuspension correction). Accuracy and precision of the trap method are discussed. A comparative analysis of sinking velocity values of large particles (marine snow, fecal pellets and zooplankton carcasses) obtained by different methods is carried out. Some modern traps and suspension systems are described; considerable progress in video recording is noted; reasonable traps to collect zooplankton carcasses are choosen. |
