Summary: Oxygen consumption in aquatic sediments is a key indicator of overall biological activity in an ecosystem. However, there has been a lack of direct measurements of sedimentary oxygen consumption in Antarctic subglacial aquatic sediments. This study provides the first microsensor oxygen profiles and derived sedimentary oxygen consumption rates in these environments, revealing relatively low rates comparable to ice-free polar oceans and oligotrophic Arctic lakes. The presence of oxygen in Antarctic subglacial sediments is important for supporting oxygen-consuming microorganisms in these ecosystems.

Summary: The Southern Ocean is characterized by high eddy activity and high POC content in summer, especially near Antarctica. Coastal water rich in POC is often trapped by nonlinear cyclonic eddies near the coast before being transported offshore. This leads to an enrichment of POC in offshore waters off the West Antarctic Peninsula.

Summary: This study investigates the variability and changes in carbon stocks on the seabed of Antarctic fjords, revealing a more complex scenario than previously assumed. The research suggests that blue carbon stocks and recent gains around Antarctica may be higher than previously estimated, indicating a stronger negative feedback on climate change.

Summary: This study investigates the significant exchanges between the Mid-Atlantic Bight continental shelf and the neighboring open ocean induced by shelf water streamers generated by Gulf Stream warm-core rings. The satellite-measured data and in situ measurements show the evolution and characteristics of the streamer, including its onshore transport of heat and salt and offshore transport of organic carbon and oxygen.

Summary: Arctic rivers are important channels for transmitting signals of change from the changing landscape to the ocean. This study reveals a previously overlooked contribution from aquatic biomass in the particulate organic matter (POM) flux. It also suggests that climate change-induced warming and increasing CO2 concentrations could enhance soil destabilization and aquatic biomass production, leading to increased POM fluxes to the ocean.

Summary: Demand for and production of organic fresh food play an increasing role worldwide. To support organic food logistics operations, benefits of facilitating real-time product data along delivery and storage processes are investigated. The results indicate that considering shelf life data in supply chain decisions can reduce food losses and enable surplus inventory to be shifted to alternative distribution channels.

Summary: This study provides a comparative analysis of carbon dynamics in different types of North American swamps, highlighting differences in carbon fluxes, biomass, and net primary productivity. The findings suggest that broad-leaved swamps have the highest methane flux, soil bulk densities, and lowest organic matter contents, while needle-leaved swamps have the highest aboveground biomass and net primary productivity. Despite the abundance of swamps in Canada and the United States, there is a significant lack of studies focused on swamp carbon dynamics.

Summary: Over 1.3 billion tonnes of food are wasted globally each year, leading to significant greenhouse gas emissions. The Food Bank of Navarra plays a crucial role in reducing this waste and associated emissions. Without the actions of the food bank, a much higher amount of CO2 would have been released. The findings highlight the importance of integrating food banks into climate change policies.

Summary: With the growing consumer demand for natural and healthy convenient food, the demand for organic convenience food has also increased. Consumers prefer organic processing technologies that maintain the product's naturalness, have fewer processing steps, and low environmental impact. Engaging consumers in understanding the benefits of processing technologies, rather than specific details, remains challenging when developing new technologies.

Summary: The study evaluated the impact of a cobia farm on nematode assemblages and found significant changes during the rearing cycle, including increased abundance, low diversity, and changes in trophic group dominance. The research indicated that fish farming in oligotrophic and dynamic tropical regions can lead to alterations in nematode communities.

Summary: This study evaluated the behavior of three paint systems exposed to the Antarctic marine environment for 45 months compared to a control of uncoated carbon steel. The study assessed the environmental conditions and analyzed the paint systems before and after exposure. The results showed that the best behavior was found for the system whose top layer was acrylic-aliphatic polyurethane.

Summary: This study investigates the benthic carbon sedimentation, remineralization, and iron cycling in the sediment cores retrieved from the eastern shelf of the Antarctic Peninsula. The results show that marginal sea ice conditions have a positive influence on sedimentation and remineralization rates. The study also reveals a significant covariation between dissolved iron and phosphate concentrations, indicating a tightly coupled phosphate-iron recycling. These findings suggest a clear bentho-pelagic coupling that could be affected by future climate change.

Summary: Time series data from a moored array of sensors are used to describe the long-term mean circulation and seasonal variations on the West Florida Continental Shelf. The observations reveal a coherent shelf-wide circulation pattern with alongshore and down-coast flow, and a coastal jet separating an upwelling region from a downwelling region influenced by the deeper ocean.
