Summary: While ecosystem health is improving in many estuaries worldwide following nutrient reductions, inconsistent trends in water clarity often remain. The study in Chesapeake Bay found that some measurements of downstream estuarine water clarity appear to be uncorrelated with watershed management actions, indicating the need for multiple metrics to address the issue. Satellite remote sensing provides an additional tool to assess long-term change in water clarity.

Summary: Phytoplankton monitoring is crucial for understanding aquatic ecosystems worldwide. This study combines microscopy and eDNA metabarcoding to investigate the phytoplankton community in Urdaibai estuary, revealing significant variations in composition under different environmental conditions. Metabarcoding identified additional species not observed with microscopy, while microscopy overcame the quantification limitations of eDNA metabarcoding. A combination of techniques is recommended for comprehensive insight.

Summary: The study on the Deba and Urola estuaries reveals significant environmental changes at millennial, centennial, and decadal timescales, primarily influenced by regional driving forces such as fresh-water discharge, relative sea-level variation, and industrial development. These changes include shifts in hydrodynamic structure, salinity, and marine influence in the estuaries at different timescales.

Summary: Monitoring biodiversity and the impact of human activities is crucial due to anthropogenic climate change. Intertidal areas face high pressures due to increased population density in coastal regions. Remote sensing is being increasingly used to monitor intertidal areas as traditional methods are not cost-effective or timely. However, accurately distinguishing between vegetation classes such as seagrass and green algae using multispectral data has proved challenging, often requiring hyperspectral data.

Summary: This study surveyed the zooplankton community in five estuaries along the Basque coast and analyzed the differences in exotic species and water temperature. The results showed that all estuaries were colonized by Oithona davisae, but not by Acartia tonsa and Pseudodiaptomus marinus. Environmental factors and secondary spread opportunities were found to contribute to the observed differences.

Summary: Bottom friction plays a crucial role in coastal and estuarine environments by reducing wave heights and moderating tidal currents. While modeling systems with varying hydraulic properties, bottom friction values are usually obtained from land use classification products. However, estimating bottom friction for vegetated areas is more challenging due to the complex and time-varying geometry of roughness elements. In this study, we integrate a dynamic friction model that considers the temporal variation in submerged aquatic vegetation (SAV) drag forces into a depth-integrated coupled circulation-wave model.

Summary: Using a combination of historical aerial photography interpretation and Bayesian modeling, we mapped the upper limits of P. oceanica meadows and identified the key disturbance factors along the coast of Giglio Island. The study revealed that human-mediated impacts such as harbour expansion, mining, and anchoring had significant effects on seagrass coverage. The findings highlight the importance of implementing management actions to mitigate these adverse effects and preserve P. oceanica beds.

Summary: Over the last decade, xenoestrogenic effects have been observed in thicklip grey mullet populations in contaminated estuaries, resulting in intersex condition. A study on the genetic structure and connectivity of Chelon labrosus from Basque estuaries using microsatellite markers revealed a high level of genetic homogeneity and panmixia across the Atlantic and Mediterranean basins. This supports the hypothesis that individuals in estuaries with intersex conditions belong to the same genetic group as those in adjacent estuaries without xenoestrogenicity.

Summary: Extreme events and disturbances have significant impacts on the carbon cycling in coastal oceans. Satellite remote sensing can greatly enhance our ability to monitor and quantify these impacts, especially in the coastal zone. This review discusses recent studies that have used a combination of field data, numerical models, and satellite observations to assess the effects of extreme events on carbon fluxes and cycling in the coastal zone.

Summary: The study identified four climate regime shifts in the Bay of Biscay, including sea warming, deepening of the winter mixed layer depth, sea-level rise, and increase of extreme wave height events. These changes may have impacted benthic communities and commercial species, with the climate conditions in the region not entirely matching the expected scenarios.

Summary: This study investigates the spectral features of remote sensing reflectance in marine waters during coccolithophore blooms by analyzing radiometric data from Ocean Color sites in the Western Black Sea. The results confirm an increase in reflectance in the blue-green spectral region during coccolithophore blooms, as well as a shift towards the blue as the blooms decline and coccoliths accumulate at the surface. It also highlights the challenges in determining bloom states in optically complex waters and compares satellite data with AERONET-OC radiometric data to show agreements in extreme conditions with significant concentrations of coccoliths.

Summary: This research aims to identify potential areas for marine aquaculture operations in the central and northern Pacific coast of Costa Rica, considering different operation scale scenarios and commercial fish species. The results show a high potential for large and medium-scale aquaculture projects, with three out of five study species presenting high suitability. Small-scale operations also have several areas suitable for aquaculture projects. The Pacific coast of Costa Rica presents high potential for fish aquaculture, which could be a promising development medium for coastal communities as long as it is environmentally sustainable and compatible with other coastal activities such as tourism.

Summary: This study compares the impacts of salinity regime and chemical pollution on the biodiversity patterns of estuarine benthic communities. The results demonstrate that the abundance of opportunistic species increases with the pollution gradient, while biotic indices are sensitive to salinity regime. Diversity increases in habitats with less frequent and shorter extreme drought and flood events.

Summary: Modelling the distribution of introduced seaweed species is challenging. This study examines the use of simplified models and the tuning of algorithm configurations to improve predictions. The results show that models with more predictors generally perform better, with Random Forest and Generalized Boosting Models scoring the highest. However, these models may have unrealistic or overfitting response curves. Generalized Linear Models and MAXENT, despite lower scores, produce smoother curves. It is important to consider both quantitative and qualitative methods when selecting optimal model configurations.

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.
