Sediment deposition and accumulation rates determined by sediment trap and 210Pb isotope methods in the Outer Puck Bay (Baltic Sea)

open access: yesOceanologia, 2014
Two methods – in situ sediment trap experiments and an isotopic method based on measurements of 210Pb activities in the sediment cores taken near the traps – were applied for determining sediment deposition and sediment accumulation rates in the eastern ...

Effect of the standard levels of forest road segments on soil loss

open access: yesJournal of Forest Science, 2021
Roads with the low standard level are often more susceptible to soil loss and production of sediment during rainfall events. The main aims of this research were to investigate the relationships between the standard level of the road and soil loss and ...
