Opis:: Praca przybliża problemy związane z wydobywaniem urobku czerpalnego w polskie strefie przybrzeżnej oraz istniejące luki prawne w tym zakresie. Szczególnie naglącą sprawą jest opracowanie nowych aspektów prawnych w prawodawstwie polskim zawierających kryteria oceny stopnia zanieczyszczenia wydobywanego urobku, wyznaczania nowych klapowisk oraz zasad ich monitoringu. Autorzy opracowania skłaniają się też do rozwinięcia idei praktycznego wykorzystania urobku, w tym kryteriów do sztucznego zasilania brzegów.
The aim of this work is introducing the problems associated with the dredging of sediment in the Polish coastal zone and pointing no rules in Polish legislation in this regard. A particularly pressing issue is to develop a new legal aspects of Polish legislation containing the criteria for dredging material and principles for new locations of spoil dredging material in the sea and of their monitoring. The authors also tend to develop the idea of the practical use of dredging sediments, including the criteria for artificial supplement the deficit of sediments of the coastal zone.

Opis:: The study area is located on the Islands of Wolin and Uznam on the Pomeranian Bay coast (Southern Baltic). In Poland, the barrier extends for 16 km. It consists of two sand spits formed between morainic plateau of these islands. At present, the entire barrier is covered by dune ridges formed since Atlantic period (5 000 BP). The youngest ridges (White Dunes) have been growing up since 17th century. Here, during last the 20 years two foredunes have grown up. The last one arose between 1997-2001. On this area author has been carried investigations since end of 1996. Investigations consist of relief measurements of different dune ridges and deflation hollows, phytosociological transects across the ridges (dune vegetation cover and variability of plant species), surface sand sampling and wind measurements. In this work long term of the foredune and upper beach changes were described. In separate parts of the sandbar, during last 14 years abrasion and aeolian processes with plants influence played main role. In the end of 2007, near profile 420th km (middle part of sandbar) on the upper beach embryo dunes formed ridge up to 4 m high. Now this form is rebuild into a new foredune. The foredune and the beach in the middle part of the sandbar are now sufficiently stabilized by grasses and wide enough to withstand heaviest storms. In other parts of sandbar dunes are stili affected by abrasional processes. Sand volume changes show visible increase of the foredunes in accumulative - middle part of the studied place. Sand volume dynamics rate in foredunes reached up to 120 m³ per one meter wide profile in the middle part of sandbar. Accumulation there reached up to 40 m³/m.

Tytuł:: Benthic Foraminiferal Assemblages and Biotopes in a Coastal Lake: the Case Study of Lake Varano (Southern Italy)

Opis:: The benthic foraminiferal assemblages in Lake Varano (southern Italy) have been investigated in detail. Statistical analyses enable us to recognize two main biotopes and five sub-biotopes that reflect different ecological and environmental conditions. The assemblages mainly seem to be influenced by the hydrological (namely salinity) and sediment conditions in the lake. These biotopes are characterized by specific sub-assemblages and variations in relative species’ abundances. The Outer Lake Biotope is affected by marine influence and is dominated by the foraminiferal species Ammonia beccarii, Ammonia parkinsoniana and Aubignyna perlucida, which are more common in open water environments. In contrast, the Inner-Marginal Lake Biotope reflects more restricted conditions where low salinity values and sand are associated with high numbers of miliolids. These two main biotopes are thus subjected to different degrees of confinement and water residence times, both of which are related to the water exchange time of the lake with the Adriatic Sea. In addition five sub-biotopes (Intermediate Marine, Mixing, “Urban”, Marginal, and Innermost) represented by particular foraminiferal assemblages are identified that characterize particular sub-environments. These sub-biotopes are, to some extent, separated by salinity gradients as well as the grain-size and the organic matter of sediments.
