Summary: This article investigates the generation and distribution of halogenated natural products (HNPs), specifically halomethoxybenzenes (HMBs), in the ocean and on land. The study finds that HMBs are present in air, precipitation, rivers, forest fungi, and litter. HMBs volatilize and circulate through the atmosphere, precipitation, and rivers, and their production and biogeochemical cycles are influenced by climate change. The study suggests that BAs and DAME are potential indicators for partitioning and exchange processes.

Summary: Coastal waters exhibit strong gradients in dissolved organic matter (DOM) quantity and characteristics, which originate from terrestrial inputs and autochthonous production. Different coastal systems show varying impacts on DOM, influenced by land use in the catchments, suggesting that the ratio of DOC:DON and DOC:DOP in tributaries may be affected.

Summary: Coastal lagoons and estuaries are hotspots for river basin-related plastic leakage, but knowledge about pollution in lagoons is limited. This study proposes a monitoring methodology for sandy inner-coastal waters that can provide comparable results to existing methods.

Summary: This study investigated the stability and variability of seaweed-associated bacteria across the Atlantic-Baltic Sea salinity gradient. Results showed that bacterial composition was strongly influenced by salinity and host species, with distinct communities in low and high salinity regions. A small taxonomic core community was identified, contributing to 14% of reads per sample, and core taxa followed a gradient model, facilitating host adaptation across the environmental gradient.

Summary: Temperature and salinity are crucial factors in marine habitats and gas fluxes. Using data from temperature and salinity monitoring in the northern Baltic Sea since the 1960s, as well as Argo buoy data from specific regions since 2012, linear trend analysis revealed an increase in near-bottom temperature and a decline in surface salinity. The data also indicated a correlation between deep-water temperature increase and global change in the Gotland Basin.

Summary: This study estimated the annual predation mortality of perch by great cormorants in the coastal waters of the northern Baltic Sea. The results showed that the annual predation mortality ranged from 4-10% depending on the sea area, with 80% likelihood limits ranging from 3% to 21%. The estimates of cormorant-induced mortality were lower compared to a recent perch tagging study in the Quark.

Summary: This study assessed changes in coastal plant community composition under altered water level and salinity scenarios through a three-year mesocosm experiment. The results showed that different plant communities responded differently to changes in water level and salinity, with significant shifts in species richness and abundance. These findings highlight the importance of conserving these important ecosystems in the face of climate change.

Summary: An operational system has been developed at the Finnish Environment Institute for multi-sensor data fusion, which accurately models chlorophyll-a concentration in water. The system utilizes Ensemble Kalman filter and smoother algorithms to account for uncertainty and spatial and temporal correlations in the observation data, improving water quality monitoring and ensuring compliance with ecological standards.

Summary: During the last decades, the Baltic Sea has experienced rapid warming due to increasing air temperatures and lateral advection of heat. Through a hindcast simulation, it has been found that the strong bottom water warming in the western Baltic Sea is linked to a shift in the seasonality of saltwater inflows from the North Sea. These changes, partly driven by a shift in river runoff seasonality, have ecological consequences, including faster oxygen depletion.

Summary: The water mass in the East China Sea shelf has a complex 3D hydrologic structure. This study used 3D interpolation technology to reconstruct the hydrologic structure based on in situ observations, and found that the cubic and thin plate spline RBFs were accurate methods. The reconstruction showed a reasonable 3D hydrologic structure and provided detailed information on the water masses, while also evaluating satellite-derived sea surface temperature.

Summary: The Baltic herring stock biomass has decreased by 80% since the 1970s, but the local effects of this decline have not been assessed. We conducted hydroacoustic surveys and trawling to investigate herring abundance and recruitment in the inshore areas. The fish community composition has significantly changed, with a decline in young-of-the-year herring and an increase in three-spined stickleback.

Summary: Seawaters exhibit various cyclic and trend-like temporal alterations in their biological, physical, and chemical processes, which can be identified and classified using remote sensing technology. By computing time series distances of large datasets, areas with similar reflection dynamics can be recognized. This method helps in identifying environmental changes and threats.

Summary: Microplastics in marine ecosystems serve as microhabitats for diverse toxic plankton species, including viable resting cysts of dinoflagellates. The diversity of plankton communities on the plastisphere is influenced by anthropogenic factors. This study highlights the importance of plastics as vectors for the transport of harmful opportunistic species in the marine environment.

Summary: The Barents Sea, as the largest Arctic shelf region, plays a vital role in supporting commercial fisheries. The ecosystem of this region is significantly influenced by both warm Atlantic Water (AW) and cold Arctic Water (ARW), resulting in distinct frontal zones. This study found that copepod populations, particularly herbivorous copepods, were most abundant and productive in the Polar Front, as well as in the eastern frontal zones. The geographic positions of sampling stations, depth, and chlorophyll a concentration were identified as the main factors influencing copepod biomass and production.
