Summary: Based on the planned FAO Ecosystem Restoration Programme, the relationship between seagrass and eelgrass areas and fish harvest in coastal lagoons was studied. It was found that fish harvest and seagrass area and biomass increased with moderate catchment total suspended sediment and total phosphorus loads. Well-managed catchment management works can help maintain seagrass for estuarine and offshore fisheries. Further research is needed to investigate the migration of estuary-dependent post-juveniles to nearshore, offshore, and shelf marine fisheries.

Summary: In coastal wetlands, groundwater flows are crucial for the establishment and nutrient transport. This study analyzes the impact of groundwater discharge on the dynamics of dissolved nutrients in the Punta Rasa Natural Reserve. A monitoring network was used to determine groundwater flows and sample dissolved N and P species. The presence of sandy sediments in all environments creates homogeneous aquifers. Fresh to brackish groundwater flows from dunes and beach ridges to marshes and coastal lagoons, contributing nutrients derived from organic degradation and possibly atmospheric sources. Nitrification dominates under oxidizing conditions, while phosphorus is mainly retained in sediments. Groundwater discharge provides dissolved nutrients, especially NO3-, to the wetlands, but it is limited due to low hydraulic gradient and oxidizing conditions.

Summary: Coastal lagoons are an important priority habitat in the European environment due to their diverse biological communities. They are relatively recent geological formations that are susceptible to rapid disappearance if environmental conditions change. In the Mediterranean basin, 37 coastal lagoons with a surface area greater than 10 km(2) have been identified. However, most of these lagoons are facing pollution and eutrophication issues, impacting their ecological condition. It is crucial to protect and preserve the cultural values associated with these lagoons.

Summary: Estuaries and their catchments play a crucial role in the cycling of dissolved organic matter and nutrients, with ICOLLs impacting the biogeochemical processes and release of nitrogen and carbon into coastal environments. Despite low inorganic nitrogen concentrations, the eutrophic ICOLL studied in southwest Australia experiences issues such as algal blooms and low dissolved oxygen, highlighting the importance of considering dissolved organic nitrogen in nitrogen studies. Including dissolved organic nitrogen in nitrogen studies may have a significant impact on the current understanding of the global nitrogen budget.

Summary: Through visual analysis of over 3000 satellite images from 2013 to 2020, it was found that stationary polynyas were common in coastal lagoons in the Northern Hemisphere of the boreal and polar climate zones of the Atlantic, Pacific, and Arctic Oceans. The polynyas were classified into flowing and inlet types, with the latter further divided into three subtypes. The distribution and mechanisms of polynyas in the lagoons were discussed, with statistical distributions showing a lognormal distribution function for the polynya areas.

Summary: Bacteriohopanepolyols (BHPs) are lipid molecules produced by bacteria and this study characterized their distribution in lakes and coastal lagoons of the Azores Archipelago. High abundance of BHPs associated with methane-oxidizing bacteria were found in sediments of low-oxygen lakes, while water columns contained dominant BHPs such as BHT. Nucleoside BHPs were found in low abundance under oxic conditions but increased near the chemocline, suggesting in situ production. Different BHPs were detected in coastal lagoons, indicating their potential as taxonomic markers.

Summary: Direct measurements in Al-Shabab and Al-Arbaeen lagoons along the Red Sea coast indicate these lagoons as significant sources of N2O to the atmosphere. The accumulation of N2O is caused by nitrifier-denitrification in oxygen-depleted bottom waters. The ongoing developmental activities may worsen hypoxia and associated biogeochemical feedbacks, emphasizing the need for continuous monitoring of the lagoons.

Summary: This study investigated the interaction of waves over a gently sloping subtidal ramp with an intertidal platform. The frequency shift in waves was observed to occur at a depth of 7 meters, with the primary development of infragravity waves happening at depths less than 5 meters. The offshore energy signal was found to be modulated by tides, with infragravity waves potentially escaping seaward across the platform edge during high tide.

Summary: This study investigates the sedimentary sequences in estuaries in north west Nelson region of central New Zealand to determine the timing of the end of the Post Glacial Marine Transgression. The study reveals that the Parapara Inlet infilled due to lateral flood tide, fluvial delta progradation, and central basin infill at a consistent rate during the mid to late Holocene periods. Similarities in sea level curves for the end of the post glacial marine transgression at stable sites in northern New Zealand suggest a true eustatic signal for the New Zealand archipelago.

Summary: This study used UAV measurements to investigate how to extrapolate across different spatial scales. The results showed that randomly sampling a certain number of samples could represent the entire landform morphology well, while sample size had little effect on representativeness. The study also observed a spatial pattern of rock surface morphology on the shore platform, with higher slope and roughness at the seaward end indicating more intensive wave processes and erosion agents.

Summary: Intermittently Open/Closed Estuaries (IOCEs) are estuaries that periodically close and can be artificially opened to relieve flooding. Whether an estuary remains open and drains its lagoon depends on the hydraulic gradient at opening and offshore wave height. Artifical openings are only successful when the hydraulic gradient is steeper than 0.017 m/m and wave height is below 4.30 m.

Summary: The patterns and driving factors of vegetation expansion during dune stabilization were examined in three coastal dunefields in Victoria, Australia. The trajectory of vegetation expansion was found to be determined by dunefield topography, with colonization occurring at different parts of the dunefield. Pre-existing vegetation played a critical role in dune re-vegetation and subsequent expansion, as it provided seeds and changed the micro-climates. This research provides important insights into vegetation expansion during dune stabilization and can help identify management intervention opportunities.

Summary: Intermittently Open/Closed Estuaries (IOCE) have entrances that close during low river flow, leading to stratification of salinity, dissolved oxygen and water temperature. These stratification changes, caused by rapid water level change and loss of oxygenation during draining, often result in fish kills. However, there is a lack of studies on the statistical relationship between environmental variables and stratification, as well as quantification of stratification changes during draining period in multiple IOCE. Our research filled these gaps by analyzing the relationships between environmental variables and stratification, and measuring physicochemical depth profiles during estuary openings in Victoria, Australia.
