Summary: Subtropical ocean gyres play a crucial role in modulating the global climate system by redistributing energy between low and high latitudes. Recent poleward displacements of the subtropical gyres may increase oceanic CO2 release, impacting climate system dynamics. Paleoceanographic records offer insights into meridional variations of subtropical gyres and their consequences on climate.

Summary: Previous studies have suggested that the South Atlantic subtropical gyre has been expanding, shifting poleward, and intensifying. Investigating from an observational standpoint, analyzing seasonal and interannual variability, and long-term trends. The gyre strength follows seasonal heating and cooling, largely influenced by sea surface height gyre maximum, while ocean mass variability is driven by wind stress curl and out of phase with the steric signal. Interannual changes to the southern boundary and gyre strength are related to wind stress curl.

Summary: Mesoscale eddies, both anticyclonic and cyclonic, have been found to act as net sinks for CO2 in the South Atlantic Ocean over their lifetimes, with anticyclonic eddies showing an exponential decrease in net CO2 sink and cyclonic eddies showing a linear increase. The cumulative impact of these eddies significantly enhances the CO2 sink into the South Atlantic Ocean. Resolving eddies explicitly is crucial for assessing the ocean carbon sink.

Summary: This study reveals the interaction between spring South Atlantic sea surface temperature and summer storm-track activity, which modulates the hemispheric atmospheric circulation and affects Antarctic summer sea ice concentration. The warm SST anomalies in the western South Atlantic frontal zone can lead to increased sea ice concentration in the eastern Ross Sea and decreased concentration in the northwestern Weddell Sea. These findings suggest a potential impact of midlatitude South Atlantic variability on South Pole air temperature variability.

Summary: This study shows that the atmospheric Arctic Dipole (AD) modulates the inflows of warm subarctic waters, affecting sea ice, oceanic circulation, and heat fluxes in the Nordic Seas. The AD+ phase slows sea-ice loss, while a transition to the AD- phase may accelerate the decline of Arctic sea ice.

Summary: Plastic pollution is widespread in the marine environment, with emerging research on microplastic pollution in Antarctic sea ice. Sea ice serves as an important seasonal sink for microplastics, with positively buoyant microplastics dominating Arctic sea ice and neutrally buoyant plastics dominating Southern Ocean sea ice. Further observational data is needed to understand the transport and accumulation of microplastics in the Southern Ocean.

Summary: Antarctic fur seals at South Georgia primarily feed on Antarctic krill, with foraging trips limited by the need to provision their pups. After breeding, female seals disperse to feed and recover condition, with potential interaction with the krill fishery at South Georgia during the winter months. Tracking data from female fur seals in winters of 1999 and 2003 reveals extensive distribution around South Georgia, with small areas of overlap with the krill fishery. These findings have implications for management and future research.

Summary: A three-dimensional hybrid modeling method was used to study the generation and propagation of T waves in the ocean triggered by a Southern Mid-Atlantic Ridge earthquake. The results suggested that T waves with clear modal features could be generated by the concentration of reflected head waves in two depressions 40km away from the epicenter, and the advantages and limitations of each approach were discussed.

Summary: This study aims to characterize the Atlantic symmetric pattern (ASP) which is established by the South America summer monsoon over the Atlantic Ocean during January and February. The ASP is manifested as two anomalous cyclonic-anticyclonic-cyclonic circulation trains aligned meridionally over the Atlantic, with distinct sea surface temperature (SST) dipole of the Southwest Atlantic Ocean and a tripole of the North Atlantic Ocean. The ASP is excited by convective activity in the SA summer monsoon and has important implications for linking South Atlantic SST, the SA summer monsoon, and North Atlantic climate.

Summary: Allochthonous resource fluxes mediated by organisms crossing ecosystem boundaries are crucial for resource-limited environments. Invasive species like black rats disrupt the natural pathways of nutrient subsidies. This study examines the role of seabirds in subsidizing terrestrial food webs and coral reefs in the Abrolhos Archipelago. The results show that seabird subsidies lead to overall enrichment of N-15 across the food web on islands. However, contrary to other studies, delta N-15 values were consistently lower within the seabird colonies, suggesting localized depletion in N-15 in small islands influenced by seabirds. Additionally, seabird presence has a higher effect on the base of the trophic web.

Summary: An out-of-season RSV epidemic was observed in Portugal from June 2021 onwards, with a longer epidemic period compared with previous seasons. Possible reasons include relaxation of COVID-19 physical distancing measures and a greater proportion of population susceptible to disease. Year-round surveillance RSV surveillance systems should be implemented to monitor changes in RSV activity.

Summary: A study in the Abrolhos archipelago found that black rats on different islands have different patterns of resource utilization, possibly due to varying levels of spatial segregation among habitats. Rats on the larger island relied heavily on seabird resources, while rats on the smaller island only benefited from seabird resources if they were sampled inside the breeding colony. This difference may be related to higher population density on the smaller island.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
