Seasonal changes of 137Cs in benthic plants from the southern Baltic Sea
137Cs activity concentrations were determined in samples of macrophytes Polysiphonia fucoides (red algae) and Zostera marina (vascular plant) collected during the entire vegetation season in the Gulf of Gdańsk in the southern Baltic Sea. The measurements showed considerable seasonality of 137Cs activity in both species; an increase of cesium concentrations was observed from spring to autumn wit...
متن کاملSpatiotemporal Variations of the 90Sr in the Southern Part of the Baltic Sea over the Period of 2005–2010
The Baltic Sea is one of the most contaminated seas by the radioactive isotope of strontium in the world; therefore the activity of ⁹⁰Sr is regularly controlled. Due to that fact, seawater samples for ⁹⁰Sr determination were collected at 16 stations located in the southern Baltic Sea between 2005 and 2010. In this period average activity of ⁹⁰Sr was 7.8 Bq m⁻³ and varied within the range from 3...
متن کاملOn variations of volumetric activity of 90Sr and 137Cs in the Baltic Sea coastal waters near the shore of Lithuania in 2005–2009
The article presents the measurement results of the volumetric activity (VA) of artificial radionuclides 90Sr and 137Cs in the coastal waters of the Baltic Sea near the Curonian Peninsula in 2005-2009. The annual average values for this period of time were 12 Bq/m3 (90Sr) and 40 Bq/m3 (137Cs). Considerable variations in the VA of the radionuclide in individual measurements compared to the avera...
متن کاملDistribution of 137Cs in benthic plants along depth profiles in the outer Puck Bay (Baltic Sea)
A study was conducted on three macroalgae species: Polysiphonia fucoides and Furcellaria lumbricalis, the species of the red algae division, and Cladophora glomerata, representing the green algae division, as well as Zostera marina, representing vascular plants. The main aim of the study was to recognize the level of 137Cs concentrations in the plants, which could be used as a measurement of bi...
متن کاملProjected future climate change and Baltic Sea ecosystem management
Climate change is likely to have large effects on the Baltic Sea ecosystem. Simulations indicate 2-4 °C warming and 50-80 % decrease in ice cover by 2100. Precipitation may increase ~30 % in the north, causing increased land runoff of allochthonous organic matter (AOM) and organic pollutants and decreased salinity. Coupled physical-biogeochemical models indicate that, in the south, bottom-water...
