Summary: Considering trophic relationships in seagrass meadows is crucial for explaining and predicting their temporal trajectories, as well as implementing conservation policies. In this study, the reciprocal links between an intertidal seagrass species and a herbivorous bird were investigated using Earth Observation and bird census data. The results showed a mutual relationship between seagrass and the bird species, with positive effects on both populations.

Summary: Studies on periphyton communities in 91 Irish lake waterbodies show that diatom composition is mainly influenced by environmental gradients such as acidity-alkalinity, total phosphorus, and true color. While diatom composition differs among high status lakes in different alkalinity groups, the Lake Trophic Diatom Index (LTDI) shows similar responses across lake types. Seasonality plays a limited role in influencing the diatom populations, allowing for unbiased monitoring throughout the growing season in temperate waterbodies.

Summary: Recent studies have found that climate warming is causing a delay in tropical rainfall over land due to the increasing influence of greenhouse gases and anthropogenic aerosols. This delay, primarily driven by external forcings, is expected to further amplify in the future as greenhouse gases increase and aerosols decrease.

Summary: The global seasonal cycle of energy in Earth's climate system is quantified using observations and reanalyses. Closure of the global seasonal energy budget is achieved by limiting the local vertical integration of new global ocean heat content estimates to the depth to which seasonal heat energy is stored.

Summary: This study analyzes historical climate simulations to determine the cause of the positive trend in the seasonal amplitude of surface ocean pCO(2) and finds evidence of anthropogenic forcing. The results indicate that the trends in mid-latitudes are attributable to human activities, while no trends are detected in the tropics and the Southern Ocean.

Summary: It is found that while the Community Earth System Model (CESM2) has shown relative improvements in many terrestrial carbon cycle benchmarks compared to its predecessor, its interannual variability (IAV) in net terrestrial carbon fluxes did not show similar improvements. The low IAV in net fluxes may have resulted from low variability in gross primary productivity (GPP), especially in the tropics, and a high covariation between GPP and ecosystem respiration.

Summary: This study used a network of multi-parametric probes to continuously monitor dissolved oxygen (DO) in the Marano and Grado Lagoon in the northern Adriatic Sea, Italy. The results showed that DO exhibited high variability in both spatial and seasonal distribution, and was influenced by solar radiation and water temperature. In some areas with limited water renewal, DO was below the minimum requirement for aquatic life. However, inputs of freshwater discharge from inland and marine waters during tides were able to oxygenate most of the lagoon effectively.

Summary: A spatial analysis of the mudflat community before and after experimental oyster reef removal in Bourgneuf Bay, France reveals that oyster reefs influence the distribution of microphytobenthos through predator facilitation. Oyster reefs play an important role in shaping ecosystem processes, and their expansion can potentially affect the sustainability of local fisheries and bird conservation.

Summary: This study evaluates the effectiveness of UAV-photogrammetry and UAV-LiDAR techniques in salt marsh habitats, and analyzes the best sensor configuration. The results show that UAV-photogrammetry provides the highest spatial resolution but requires long processing times and is suitable only for small areas, while UAV-LiDAR offers shorter processing times and lighter datasets, with improved effectiveness when combined with multispectral data for vegetation classification.

Summary: The researchers investigated four adjacent vegetated coastal habitats in Cadiz Bay, South Spain, and found that subtidal seagrass Cymodocea nodosa had the highest organic carbon and total nitrogen stocks, followed by upper intertidal salt marsh Sporobolus maritimus, subtidal rhizophytic macroalgae Caulerpa prolifera, and lower intertidal seagrass Zostera noltei. They also observed that sedimentation and organic carbon burial rates increased with elevation. Overall, this study emphasizes the importance of using habitat-specific carbon and nitrogen stocks and burial rates to predict the sequestration capacity of vegetated coastal habitats at the seascape level.

Summary: Blooms of Lepidodinium chlorophorum, a marine dinoflagellate, cause green seawater discolorations in southern Brittany, affecting recreational activities and tourism economy. The species is most abundant from May to November, with peak abundance in June-July. Tidal currents and stratification play important roles in the distribution of the bloom, while high concentrations of phosphate, ammonium, and TEP are recorded within the bloom. Bacterial stimulation and TEP production contribute to the sustainment of the bloom, with potential negative effects on the environment and biological resources through hypoxia.

Summary: This paper explores the factors controlling the functioning of salt marshes in the San Vicente de la Barquera estuary in Spain. The results show that the salt marsh area is declining due to fragmentation, and there is no clear pattern of vegetation loss/gain with elevation. Increased hydro-dynamic stress and human interventions are identified as major drivers of the decline in salt marshes. The study emphasizes the importance of considering both natural and human factors when developing management strategies for salt marshes.

Summary: This study aims to evaluate the accuracy of PRISMA's standard Level 2d (L2d) products for water bodies in the visible and near-infrared spectral regions. An analytical comparison with in situ water reflectance data from AERONET-OC was performed, and the results showed significant levels of uncertainty in the L2d reflectance products, especially in oligotrophic waters. It suggests the need to develop and test water-specific atmospheric correction algorithms to fully exploit PRISMA data.

Summary: In this study, an unmanned aerial vehicle (UAV) was used to detect and map surface discontinuities with displacements of a few centimeters, indicating the presence of initial geological deformations. The study found that sediments of alluvial fans are susceptible to various tectonic and exogenous deformational processes, and the interpretation of ultra-high resolution UAV images can help recognize low-amplitude brittle deformations at an early stage. UAV surveys are critical for discerning neotectonic activity and its related hazards over short observation periods.

Summary: This article investigates optimal sample allocation in stratified random sampling for estimation of accuracy and proportion of area in applications where the target class is rare. The study finds that precision of estimated accuracy has a stronger impact on sample allocation than estimation of proportion of area, and the trade-offs among these estimates become more pronounced as the target class becomes rarer. The results provide quantitative evidence to guide sample allocation decisions in specific applications.

Summary: Soil moisture and freeze/thaw (F/T) play a crucial role in water and heat exchanges at the land-atmosphere interface. This study reports the establishment of a wireless sensor network for soil moisture and temperature over the permafrost region of Tibetan Plateau. Satellite-based surface soil moisture (SSM) and F/T products were evaluated using ground-based measurements. The results show the reliability of L-band passive microwave SSM and F/T products, while existing F/T products display earlier freezing and later thawing, leading to unsatisfactory accuracy.
