First record of the foraminiferal species Ammonia confertitesta in southeastern Baltic sea [PDF]

open access: yesScientific Reports
Early identification of non-indigenous species is important, as they have the potential to disrupt biogeochemical cycles, ecosystem stability, and trophic energy transfer in fragile ecosystems.

Intra-annual distribution of Temora longicornis biomass in the Gulf of Gdańsk (the southern Baltic Sea) – numerical simulations [PDF]

open access: yesEstonian Journal of Earth Sciences, 2017
A population model of the copepod Temora longicornis coupled with the ecosystem model 3D CEMBS (Coupled Ecosystem Model of the Baltic Sea) was used to determine the intra-annual distribution of the species biomass in the Gdańsk Basin (the southern Baltic

Primary production and chlorophyll in the Gulf of Gdańsk in 1987-1988 [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1991
The paper presents data on primary production and chlorophyll a concentrations at two stations located in the Gulf of Gdańsk (Baltic Sea). The primary production in 1981 was much higher than the mean values for the region, observed in other years when ...

Budget of 90Sr in the Gulf of Gdańsk (southern Baltic Sea)

open access: yesOceanologia, 2018
Summary: In the period from 2005 to 2011 the major source of 90Sr to the Gulf of Gdańsk was the Vistula river. Its contribution was 99.7% of the total load.

Distribution and migrations of tagged rainbow trout (Salmo gairdneri Rich.) released to the Baltic Sea [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1985
41502 tagged rainbow trout were released into the Baltic Sea, mainly to the Gulf of Gdańsk, and to some Polish rivers, mainly to the River Vistula. 2504 returns from “older” fishes and 1486 from “younger” fish made

Spatial distribution of biological and physical sediment parameters in the western Gulf of Gdańsk

open access: yesOceanologia, 2013
The ongoing processes of surface sediments and their biological activity are highly dynamic. Sediment samples for the current study were collected at 48 stations in the Gulf of Gdańsk in May 2006, and the following sediment parameters were analysed ...

Canthaxanthin in recent sediments as an indicator of heterocystous cyanobacteria in coastal waters

open access: yesOceanologia, 2019
Summary: The mean share of heterocystous cyanobacteria in total chlorophyll-a production in coastal waters, based on cyanobacterial marker carotenoid and chloropigments preserved in recent sediments (0–5 cm, ca 30 years), has been studied in the Gulf of ...
