Summary: The research found that coastal waters from Fortaleza city are significant sources of anthropogenic Gadolinium, with wastewater outfall areas and local river estuaries contributing to high concentrations of Gd in the ocean. The study highlighted the potential of Gadolinium as a tracer for water management and forensic purposes, offering a conceptual model for its behavior within salinity gradients.

Summary: This review discusses the biogeochemical characteristics of tropical peatlands and explores the impacts of human activities such as deforestation, fire, drainage, and agriculture on these systems. Tropical peatlands store a significant amount of carbon, but they are increasingly threatened by anthropogenic modifications, which result in carbon loss, increased greenhouse gas emissions, and hydrological disruptions. With a warming climate, these impacts are expected to escalate, posing risks to carbon stocks in disturbed and intact peat swamps.

Summary: The change in anthropogenic CO2 in the Atlantic Ocean is linked to the Atlantic Meridional Overturning Circulation (AMOC). Advection and diffusion play important roles in the transport of CO2, with strong vertical diffusion between the upper and deep layers.

Summary: Global climate change is a fact that cannot be disputed, and human activities are the main driving mechanisms. In this study, the transit time distribution method was used to estimate the storage of anthropogenic carbon in typical marginal seas along the west side of the North Pacific Ocean and the Arctic Ocean. The results showed that the storage of anthropogenic carbon gradually increased with latitude. The transfer of CO2 from the atmosphere to the water may be promoted in the short term due to warming and declining ice cover, but a positive feedback may occur in the long term, leading to reduced CO2 absorption. Hence, the Arctic Ocean may no longer be a sink for CO2 in the future.

Summary: Tropical forests are vital for biodiversity and ecosystem services. However, anthropogenic pressures, particularly forest fires in transitional regions, pose a major threat to these services. A study found that fires decrease forest carbon stocks and disrupt their ability to absorb carbon, turning them into a carbon source for the atmosphere.

Summary: The presence of floating marine anthropogenic litter in marine environments increases the likelihood of fouling organisms using these substrates as a means of transportation. The study found that exposed beaches have higher density and cover of fouling, possibly due to currents, winds, and storm waves. Bryozoans, barnacles, polychaetes, and mollusks were the most common fouling groups observed in litter and could potentially contribute to the dispersal of species in the area.

Summary: Two centuries of human carbon emissions have resulted in increased atmospheric CO2 and dissolved inorganic carbon in the ocean. However, only 45% of the atmospheric CO2 increase can be attributed to anthropogenic carbon emissions, with the rest being natural CO2 released from the ocean. This release is driven by the seawater's carbonate buffering capacity and occurs as the dissolved inorganic carbon concentration increases.

Summary: The season-dependent impacts of the tropical North Atlantic sea surface temperature anomaly on subsequent El Nino-Southern Oscillation evolution were investigated. It was found that the TNA anomaly during boreal summer generates a stronger rainfall response and zonal wind anomaly over the equatorial western Pacific, impacting the evolution of ENSO.

Summary: Measurements of tracers in the Arctic Ocean have been used to calculate mean ages, Gamma and mixing, Delta parameters to understand water circulation and mixing time scales. The values of Gamma and Delta increase rapidly with depth, but their ratio remains approximately 1, supporting their use in deep ocean transport. The isolines of Gamma=20 years outline the return flow of Atlantic Water towards Fram Strait, while the isolines of Gamma=25 years indicate older water in the basin interior. Values of Delta remain relatively constant, suggesting that mixing occurs upstream.

Summary: The western Tropical Atlantic Ocean is a complex region for carbon cycle dynamics, with three distinct sub-regions showing different sea-air CO2 exchanges. The Amazon River plume waters play a crucial role in carbon uptake in this region. The carbon dynamics in the North Brazil Current and North Equatorial Current waters are sensitive to global climate change.

Summary: Observations from the Argo float array show a warming and freshening trend in the upper mixed layer of the southeastern tropical Atlantic Ocean, leading to increased upper-ocean stratification. Changes in wind stress and weakened coastal upwelling may explain the southward spread of tropical surface waters in the region.

Summary: Early Eocene hyperthermals are short-lived global warming events that perturb the global carbon cycle and Earth's ecosystem by adding isotopically light carbon to the ocean-atmosphere system. A study at Ocean Drilling Program Site 1258 reveals the impacts of the Eocene Thermal Maximum 2 (ETM2) and H2 events on carbon cycle dynamics, providing insights into the rapid warming and subsequent recovery mechanisms in climate and ecosystem. Modeling results show moderate ocean pH changes for the two scenarios due to biogenic methane and organic matter oxidation.

Summary: Potassium-containing fertilizers are commonly used in agriculture, but excessive use can lead to pollution. This study investigates the sources of potassium in different fertilizers from various countries using stable potassium isotope data. The results show that potassium isotope ratios and concentrations can be used to identify the impact of fertilizers in ecosystems.

Summary: The study found a significant amount of floating macroplastics and meso-/microplastics in rivers in Germany, with some hotspots potentially linked to plastic-producing industries, wastewater treatment plants, weirs, and residential areas. The identification of litter hotspots could lead to targeted mitigation measures to prevent further pollution.

Summary: Population in Africa is projected to increase significantly, with a focus on uncultivated land and greenhouse gas emissions. Due to Africa's vast size and diversity, there is still limited understanding of greenhouse gas emissions sources. Therefore, establishing an environmental research infrastructure is crucial.

Summary: The release of organic matter from thawed permafrost will impact the sources and sinks of greenhouse gases in Arctic rivers. However, little is known about the temporal variation, environmental controls, and magnitude of greenhouse gases in these rivers. This study measured the concentrations of CO2, CH4, and O2 in the Ambolikha River in northeast Siberia, revealing the effects of temperature variation, flooding, and lateral exchange on greenhouse gas emissions.

Summary: Accurate assessment of anthropogenic CO2 emissions and their redistribution among different components is critical for understanding the global carbon cycle. This study presents datasets and methodologies to quantify the major components of the global carbon budget. The results show changes in fossil fuel and land-use change emissions, as well as atmospheric CO2 concentration, ocean CO2 sink, and terrestrial CO2 sink.

Summary: Mesoscale eddies play a crucial role in phytoplankton growth in the eastern tropical North Atlantic, but their impact on organic carbon transfer and the marine carbon budget is still unclear. Measurements of eddies' contribution to bathypelagic particle flux are hard to obtain. Observations suggest efficient export of organic carbon from the surface to the deep ocean in low-oxygen eddies.
