The Baltic Sea is one of the world's largest brackish water bodies and is characterised by pronounced physicochemical gradients where microbes are the main biogeochemical catalysts. Meta-omic methods provide rich information on the composition of, and activities within, microbial ecosystems, but are computationally heavy to perform. We here present the Baltic Sea Reference Metagenome (BARM), complete with annotated genes to facilitate further studies with much less computational effort. The assembly is constructed using 2.6 billion metagenomic reads from 81 water samples, spanning both spatial and temporal dimensions, and contains 6.8 million genes that have been annotated for function and taxonomy. The assembly is useful as a reference, facilitating taxonomic and functional annotation of additional samples by simply mapping their reads against the assembly. This capability is demonstrated by the successful mapping and annotation of 24 external samples. In addition, we present a public web interface, BalticMicrobeDB, for interactive exploratory analysis of the dataset.

Introduction: Harbor seals () and grey seals () are infected by trophically transmitted intestinal cestodes of the genus . species can cause zoonotic infections in humans when larval stages are ingested with undercooked fish products. Diphyllobothriid cestode prevalence, infection dynamics, and health impact in phocid seals around densely populated coastal areas are little understood, and their species delineation remains challenging.

The capacity of river mouths to reduce storm surge water levels upstream, referred to as along-estuary attenuation, has been assessed by several studies. The coastal protection function of semi-enclosed water bodies such as lagoons and channels with narrow inlets remains less explored and generalization is hampered by differences in morphology and hydrodynamic forcing. Here we use a hydrodynamic model to investigate surge attenuation along a microtidal channel with a narrow inlet at the Baltic Sea coast of Germany called The Schlei.

The record storm surge of October 2023, which hit the southwestern German Baltic Sea, not only resulted in significant damages to coastal communities and infrastructure but also demonstrated that the region was prepared and able to avoid loss of lives and other catastrophic impacts. Numerical modelling has been a key tool utilised for providing information to support coastal flood management, at different levels of planning, for such events. Based on recent research conducted in the Baltic coast region as well as on empirical evidence acquired during the event, we present an operational scheme that utilises modelling tools and frameworks for supporting coastal flood management in the region.

The microplastics (0.3-5 mm) and mesoplastics (5-25 mm) in the non-tidal estuary of the Pregolya River (south-eastern Baltic Sea) were investigated for the first time in order to trace the retention zone (estuarine microplastic maxima, EMPM) at the river-sea interface, which is characterised by a salinity gradient. The mean abundance of all plastics (0.

The role of plastics is well-documented in the literature reflecting on its impact on a global economy, planetary and human health. However, there is an urgent need for additional studies analysing their carbon emissions and ways to handle them. This short communication discusses the measures needed to understand and mitigate plastics' carbon footprint while paving a path toward cleaner, sustainable and circular plastic industry.
