“…Water exchange, strong flows/currents in Głębinka (Matciak et al 2011) prevent accumulation of sediments, hence sediments in the southern part of the Seagull Sandbar have features of redeposition. The lack of conditions conducive to sedimentation in this region was also evidenced by research conducted using sediment traps (Szymczak & Szmytkiewicz 2014). Due to the coastline configuration and seabed topography, the Seagull Sandbar is exposed to waves from the NW direction (common -12%) and SE (very rare).…”

“…In the Outer Puck Bay, sandy silt and silty sand occur on the slope of the seabed at depths exceeding 10-15 m. Marine silty clay and clayey silt occur at depths below 20-25 m (Uścinowicz & Zachowicz, 1992, 1994. The processes of intensive erosion of morainic plateaus (Zawadzka-Kahlau 1999), fluvial supply (Szymczak & Szmytkiewicz 2014), aeolian processes (Pęcherzewski 1994), and overwashes (Wróblewski 2009) are the main source of the clastic material.…”

Puck Bay is an unusual and thus interesting coastal water region, as it combines two different environments – a lagoon and the sea. They differ from each other in their seabed morphology, salinity, dynamics and water exchange. Their common elements are the extensive shallows and the vicinity of the Hel Peninsula. The shallows of Puck Bay have developed at various stages of its evolution, which began several thousand years ago and continues to this day. They have been shaped by varying morphogenetic factors resulting from changes in sea level and accompanying evolution phases of sand barriers, e.g. washover fans, as well as the intensity and directions of sediment transport. At present, the shallows cover more than 35% of the seabed area and are influenced by hydrodynamic factors and availability of sediments. The study area was divided into five fields, taking into account morphological and genetic criteria as well as recent hydrodynamic conditions. This study provides an updated map with classification and distribution of surface sediments and describes grain size parameters for sediment samples collected in the selected fields. Based on a comprehensive assessment of grain size parameters, lithodynamic equilibrium zones were determined and areas of sediment deposition and redeposition were identified.

“…The hydrological conditions of Puck Lagoon are influenced by rivers (Reda, Płutnica and Gizdepka) flowing into it [33]. The most important one is the Reda River, introducing approximately 0.187 km 3 of water into Puck Lagoon per year [34] and accounting for approximately 66% of river inflow to the lagoon [35]. Furthermore, the Seagull Sandbar between Puck Lagoon and the outer Puck Bay limits the water exchange occurring in the northern part through the Kuźnica Passage and in the southern part through Głębinka Passage [36].…”

“…The Reda River is therefore of particular importance, with an average water flow of 5.9 m 3 s −1 , contributing metal from a catchment area of 485.2 km 2 [22,84]. Rivers introduce >12.5 tons of sedimentary material into Puck Lagoon, which is deposited near the river mouths [86]. This contributes to the increase in silty and clayey fractions in the surface sediment in this region [81,86].…”

Mercury is a toxic metal that in excessive amounts negatively affects the human nervous system. It can biomagnify to enrich successive levels of the trophic web with higher and higher concentrations of Hg. Diatoms are cosmopolitan microalgae that represent the base of the trophic web. The objective of this study was to determine the importance of diatoms in the accumulation of Hg in surface sediments in the example of Puck Lagoon (southern Baltic Sea). The study verified the relationship of mercury forms with diatoms’ characteristic salinity groups and individual diatom species. The identified diatom flora permitted the distinguishment of three regions with different salinity preferences. The obtained results suggest that, together with organic matter and fine sediment fraction, diatoms are an important element of the marine environment in accumulating Hg. Area I, dominated by euhalobous and mesohalobous diatom species, was characterized by a high statistically significant correlation of mesohalobous with HgSO4, Hg in complexes with organic matter and HgS. In Area II, associated with the highest Hg concentrations (ca. 100 ng g−1), euhalobous showed a statistically significant linear correlation with HgSO4. In contrast, in Area III, the freshwater diatom community was associated with stable Hg forms. The identified species showed a connection with labile forms of Hg that can undergo biomagnification.

Impact of sea level changes and fluvial processes on the location of the Piaśnica River mouth and the lithodynamic of bed sedimentsAbstract: The aim of the article is to analyse changes in the channel layout of the Piaśnica River estuary and the lithodynamic characteristic of bed deposits as a consequence of sea level changes. The analysis is based on the results of measurements in the river estuary conducted in the years 2014-2015. The data of daily average sea level were obtained from the Institute of Meteorology and Water Management (IMiGW) station in Władyslawowo and Łeba. The research documented distinct changes in the position of the riverbed. Analyses of textual indicators were conducted i.e. mean grain size (M Z ), standard deviation (σ I ), skewness (S kI ) and kurtosis (K G ) were calculated according to Folk and Ward formulas (1957) using the Gradistat software. Based on the abovementioned data conclusions were made about the changing conditions of the river sediment transport.
