The influence of different acids and pepsin on the extractability of collagen from the skin of Baltic cod (Gadus morhua)
PublikacjaZastosowano 5,0 M roztwory kwasu cytrynowego, mlekowego, octowego oraz 0,115 M roztwór kwasu solnego. Kolagen z całych skór ekstrahowano w 4 st.C odpowiednimi kwasami (1 : 6, w/v) w czasie 24, 48 i 72 h. Stwierdzono, że kwas solny jest najmniej efektywnym rozpuszczalnikiem kolagenu spośród użytych kwasów. W zastosowanych warunkach doświadczeń maksymalnie można wyekstrahować kwasem cytrynowym 60 % kolagenu, kwasem octowym i mlekowym...

Mathematical Modeling of Ice Thrusting on the Shore of the Vistula Lagoon (Baltic Sea) and the Proposed Artificial Island
PublikacjaCoastal lagoons are inland and shallow water bodies, separated from the ocean by a barrier. In cold regions, ice phenomena in shallow water coastal lagoons occur every winter season. Ice is predominantly formed on the surface due to density stratification and surface cooling. The ice dynamics in such areas are dominantly affected by winds. Water dynamics also cause ice movement, but due to the large areal scale of lagoons, the...

Marka South Coast Baltic jako inicjatywa promocji morskich portów jachtowych południowego wybrzeża Bałtyku
PublikacjaW regionie Morza Bałtyckiego podejmowane są różne inicjatywy mające na celu promocję wybranych grup morskich portów jachtowych. Realizowane są także projekty zmierzające do tworzenia sieci marin wokół pewnego akwenu, np. South Baltic Four Corner i Baltic Sailing lub lokalnych grup portów i przystani, np. Zalewów Szczecińskiego, Wiślanego, Kurońskiego. Na tym tle południowe wybrzeże Bałtyku stanowiło swoistą „białą plamę”. Oprócz...

Towards a multi-basin SWAT model for the migration of nutrients and pesticides to Puck Bay (Southern Baltic Sea)
PublikacjaBackground This paper analyzes the impact of changes in fertilization on crop yields and the runoff of nutrients from a small agricultural catchment (176 km2) to a shallow bay, using the SWAT model. Puck Bay is part of the Gulf of Gdansk and belongs to the Baltic Sea. The whole area of Puck Bay (364 km2) is protected (Natura 2000) yet despite this it suffers from eutrophication problems due to the relatively minimal depth and...

Habitat-related patterns of soft-bottom macrofaunal assemblages in a brackish, low-diversity system (southern Baltic Sea)
PublikacjaCoastal areas provide a high variety of sedimentary habitats that influence the structure of resident fauna even on small geographical scales. Therefore, examinations of spatial variations in benthic assemblages require background knowledge of the environmental and biotic heterogeneity of habitats in order to understand ecological processes in such areas. The effect of habitat-related abiotic and biological variables on macrofaunal...

Mobility and bioavailability of mercury in sediments of the southern Baltic sea in relation to the chemical fractions of iron: Spatial and temporal patterns
PublikacjaMarine sediments play a significant role as reservoirs for mercury (Hg), a bioaccumulative toxic pollutant that poses risks to human and ecosystem health. Iron (Fe) has been recognized as an influential factor in the complexation and bioavailability of Hg in sediments. However, limited studies have investigated the interactions between the chemical fractions of these elements in natural settings. This study aims to examine the...
