Summary: Methane bubbles can facilitate the transport of polycyclic aromatic hydrocarbons (PAHs) from lake sediments, increasing PAH concentration in the water column and offsetting dry PAH deposition flux into global lakes sediment. This process may significantly contribute to the increment of PAHs in lake waters until 2100.

Summary: This study highlights the significant but variable contribution of methane emissions from aquatic ecosystems to global greenhouse gas emissions. It suggests that the frequency of disturbance can impact methane emissions, with an intermediate disturbance frequency resulting in the highest emissions.

Summary: This study quantified diffusive and ebullitive greenhouse gas emissions from temperate fish ponds for the first time. Results showed significant variations in emissions between ponds, with methane consistently being the predominant greenhouse gas. The quantification of greenhouse gas emissions from temperate fish ponds is important for improving estimations.

Summary: Noble gases are used to trace natural waters and determine temperature conditions during equilibration. Recent measurements in Lake Kivu show a depletion of noble gases in deep waters, but no explanation has been provided. By using noble gas thermometry, it is hypothesized that high equilibration temperatures caused the observed depletion.

Summary: High-frequency methane ebullition data from a boreal pit lake showed that ebullition events typically lasted 2-4 days in response to low atmospheric pressure systems. Empirical equations incorporating a pressure threshold were provided to model the time-series of ebullition events, with minor variations in mud temperature having no significant effect.

Summary: Constructed wetlands in urban environments are commonly used to treat pollutants, but they can also be significant sources of greenhouse gas emissions, particularly ebullitive methane. This study found that ebullitive emissions, in addition to diffusive emissions, contribute to a higher Global Warming Potential than previously estimated, indicating the importance of accurately measuring and accounting for all sources of greenhouse gas emissions from constructed wetlands.

Summary: This study demonstrates that the effect of experimental warming on greenhouse gas (GHG) fluxes differs depending on the dominance of different functional plant types in inland waters. Specifically, the response to warming was strongest for free-floating plants and lowest for submerged plants. Importantly, the anticipated shift from submerged plants to algae or free-floating plants with warming may increase total GHG emissions from shallow waters, representing a positive climate feedback that has been overlooked. Management strategies aimed at promoting submerged plant dominance can significantly mitigate GHG emissions.

Summary: In 2004, a Gulf of Mexico oil platform was destroyed by Hurricane Ivan, leading to a continuous discharge of oil and gas. In 2019, a containment device was installed to prevent oil from entering the water column. Plumes of oil and gas bubbles were observed using acoustic survey, visual inspection, and water column collections. Atmospheric methane concentrations were elevated above baseline, and oil rising to the surface was identified as the main source of methane to the atmosphere.

Summary: This study measured ebullitive methane (CH4) fluxes from inland freshwater fish and crab aquaculture ponds in subtropical China over a two-year period. The results show that during the aquaculture period, ebullition is the dominant pathway of CH4 emissions in these ponds, with dissolved oxygen and dissolved organic carbon being the primary factors driving the fluxes. The study also suggests that the use of aerators can significantly reduce CH4 emissions from freshwater aquaculture ponds.

Summary: Microbial methane oxidation plays a crucial role in the global methane budget on Earth, and the isotopic signatures of methane can be used to track both aerobic and anaerobic methanotrophy. This study investigates the isotopic compositions in two different methanotrophic environments, Lake Pavin and Black Sea sediments, and reveals distinct isotopic fractionation patterns between aerobic and anaerobic methanotrophy.

Summary: Storing energy offshore using hollow concrete spheres at the sea bottom combines technical features of conventional pumped hydro storage systems with vast resource potential, but requires further R&D for large sphere design, construction, installation, and necessary electro-mechanical equipment. A scaled test using a 3m diameter sphere in Lake Constance demonstrated a fully functional system, with an outlook provided for the next development phase currently under negotiation with funding agencies.

Summary: This study explores a novel method to analyze and quantify the emissions of methane from lacustrine sediments by analyzing the concentrations of methane and noble gases in pore water. The research found that different hydro-geochemical settings in lakes can impact the gas dynamics in sediments, leading to heterogeneous emissions of methane. The potential of this combined analysis method for understanding gas dynamics in aquatic environments like wetlands and oceans is demonstrated.

Summary: Aquaculture ponds are significant sources of methane emissions but weak sources of nitrous oxide. Methane emissions are influenced by temperature, dissolved organic carbon concentration, and redox potential, while nitrous oxide flux is affected by gas transfer velocity. Nitrous oxide is primarily produced in the water column and can diffuse downwards into sediments for consumption.

Summary: Three strains of methanotrophic bacteria were isolated from the River Elbe in Germany, including two novel species within the genus Methylomonas and one member of the species Methylovulum psychrotolerans. These bacteria exhibit differences in carbon source utilization and growth conditions, highlighting the importance of identifying and classifying new species in this study.

Summary: Methane distribution in coastal waters is influenced by both riverine input and marine dilution, with higher input concentrations from the Elbe and Weser rivers in the southern North Sea. Small-scale anomalous patterns of methane concentrations were discovered, and the calculated diffusive methane flux into the atmosphere was found to be higher at certain times and locations due to increasing wind speed and methane concentration.

Summary: MOSES is an observation system designed to study the long-term impacts of dynamic events on environmental systems. It aims to capture these events, from their formation to their end, with high spatial and temporal resolution. It is a mobile and modular system to record energy, water, greenhouse gas, and nutrient cycles, especially the interactions between different compartments of the Earth.

Summary: Accurate assessment of changes in sea surface water temperatures is crucial for understanding the impact of global warming on marine ecosystems. Traditional hand measurements have been replaced with automated long-term observation stations, providing more precise and continuous data. Experimentation with different sensor types and sampling frequencies revealed the importance of selecting an appropriate frequency for detecting significant long-term temperature trends.

Summary: Rivers are significant sources of greenhouse gases, but our understanding of their emissions remains incomplete. Continuous measurements of CH4 concentrations along the German Elbe revealed hotspots at weirs and harbors, with corresponding increases in atmospheric CH4 concentrations. The morphology and structures of rivers contribute to lateral heterogeneity in CH4 concentrations, with groin construction increasing GHG emissions.

Summary: The study found that the structure of different water bodies has varying effects on ice formation and methane emissions. The ice cover of thermokarst lakes can prevent methane from being released into the atmosphere during winter, while the microenvironment beneath the ice surface may facilitate methane oxidation. These findings help us better understand the contribution of thermokarst lakes to the global carbon cycle.

Summary: The study indicates that different types of water bodies in the Arctic have varying methane concentrations and methane oxidation rates, with winter methane concentrations typically higher than summer. Temperature has a significant influence on methane oxidation rates, and MOX in lakes is generally much higher than in rivers and bays.
