Baltic Sea macroalgae exhibit unique bioactive compounds and diverse applications, supporting sustainable industries in food, cosmetics, and medicine while promoting environmental restoration. Common in the Baltic Sea, macroalgae hold great biotechnological and commercial promise in various industries, such as food, cosmetics, and medicines. The present study investigates the various uses of the Baltic macroalgae, emphasizing their nutritional worth, which encompasses vital amino acids, vitamins, and minerals, as well as their suitability as natural gelling agents, food additives, and dietary supplements. Additionally, these macroalgae's bioactive chemicals show promise as therapeutic agents due to their antiviral and anticancer capabilities, making them essential assets for the pharmaceutical and medical sectors. A lot of research has been done on macroalgae, but not much on Baltic species. With an emphasis on their unique qualities and possible benefits to environmental preservation and sustainability, this paper attempts to present a thorough review of the uses of the Baltic macroalgae.

Different natural and anthropogenic drivers impact the groundwater in the catchment area of the southern Baltic Sea, north-eastern Germany. To understand the sources and fate of dissolved sulphate, carbonate, and nitrate on a regional scale, in the present study, the hydrogeochemical and multi-stable isotope (H, C, O, S) composition of groundwater samples from up to more than 300 sites (depths from near-surface down to 291 m) was studied. To investigate the element sources and the water-rock-microbe interaction processes that took place along the groundwater flow path, a mass balance approach is combined with physico-chemical modelling.

Zinc oxide nanoparticles (nZnO), distinct from other nanomaterials, are increasingly utilized in industrial, medical, and personal care products, particularly as the main ingredient in sunscreens, raising concerns about their environmental impact, especially in coastal ecosystems. The Baltic Sea, experiencing severe eutrophication, faces persistent hypoxia due to excessive nutrient runoff and limited water exchange. Simultaneously, coastal pollution from industrial and urban activities introduces nZnO, a highly biotoxic nanopollutant.

While marine seagrass habitats are acknowledged as sinks for carbon and nutrients, much less is known about sequestration in brackish-water vegetation. Here, we quantify the amount of organic carbon (C) and total nitrogen (TN) in shallow bay sediments (0-25 cm) in the brackish Baltic Sea and assess how it varies with morphometric isolation from the sea, catchment characteristics and abundance of brackish-water vegetation. The sedimentary C and TN content per surface area varied across the bay isolation gradient (mean C: 2500-4600 g/m; mean TN: 320-570 g/m), with enclosed bays having the highest percentage content of C and TN, but low sediment density (< 0.

Automatic delineation of coastline in coastal zones is an essential task for various applications including protection of coastal regions, disaster management, and planning. The lack of availability of manually annotated high resolution datasets tailored for AI in coastal research remains a concern. Therefore, we created an open source, UAV captured and high resolution RGB dataset named MADRID (Manually Annotated DRone Imagery Dataset).
