Summary: This study analyzes the time-dependent behavior of the buoyant plume rising above Grotto Vent and identifies long-term changes in the background bottom currents, suggesting a systematic evolution in vent output along the Juan de Fuca Ridge. The behavior of the plumes can be characterized by their volume, velocity, and orientation relative to the seafloor, which are influenced by hydrothermal flux and ocean bottom currents. The findings reveal a change in plume direction and a decrease in southward bottom currents, indicating the influence of local venting rather than external ocean circulation.

Summary: The study reveals that hydrothermal vent fluids contain a variety of barium forms, but their initial composition changes due to barite precipitation. Water-rock interaction in the deep oceanic crust appears to occur without barium isotope fractionation. During mixing with seawater, barite precipitation selectively removes isotopically light barium from the fluids.

Summary: This paper presents the methods used in the search for modern hydrothermal activity areas and their long-term use in the Russian exploration area of the Mid-Atlantic Ridge. Various techniques, including CTD-sounding and teleprofiling, were employed to detect geophysical and geochemical anomalies near high-temperature, low-temperature, and inactive fields. The results show that a combination of these methods can effectively identify both low- and high-temperature hydrothermal discharges within mid-oceanic ridges.

Summary: In this study, three linearly aligned seamount chains on the flanks of the easternmost and longest Australian-Antarctic Ridge (AAR) segment, KR1 ridge, were examined. The seamounts were found to be distributed asymmetrically about the ridge axis, with some characterized by high elevation and large volume, and others smaller and mostly located on the western side of the ridge. These differences in volumetric magnitude of volcanic eruptions and distance from the ridge axis suggest the presence of magma sources with different origins.

Summary: Active hydrothermal vents provide the surrounding submarine environment with substantial amounts of matter and energy, thus serving as important habitats for diverse megabenthic communities in the deep ocean. By simulating the vent hydrodynamics, it was found that the tendency of turbulent buoyancy plumes to carry matter far away is counteracted by generated entrainment flows back into the plume stem. Plume hydrodynamics exercises strong control over the spatial distribution of vent-endemic fauna.

Summary: This study investigates the food web structure and species interactions in a hydrothermal vent community in the Central Indian Ridge. The results show that chemosynthetic production is the primary source of energy in this community, and different populations utilize distinct energy pathways to avoid competition. Multiple trophic guilds and levels are identified. The study also reveals similarities and differences between this vent community and others in the Indian Ocean.

Summary: This study implemented a novel experimental approach to assess the recovery potential of vent communities along the slow-spreading northern Mid-Atlantic Ridge. Within 2 years after inducing a small-scale disturbance, most taxonomic richness had recovered, but there was only partial recovery of faunal densities and a major change in faunal composition. The results suggest a potential role of mobile predators in early-colonisation stages.

Summary: The Cheoeum vent field represents the first discovery of an inactive ultramafic-hosted seafloor massive sulphide deposit in the middle part of the Central Indian Ridge. The mineralisation stages, with the presence of high concentrations of gold and tin, suggest that the Au-Sn mineralisation may be a common occurrence along slow-spreading mid-ocean ridges.

Summary: This study investigates the export and influence of carbon produced by hydrothermal vents on benthic food webs. It reveals that fauna near the venting area primarily rely on chemosynthetic organic carbon, while fauna further away from the vents rely more on photosynthetic organic carbon. Nematodes are the most abundant faunal taxon. These findings have important implications for future spatial management plans in deep-sea mining at hydrothermal vents.

Summary: Our study found significant differences in microbial community composition between Scaly-foot Snails samples collected from independent hydrothermal vent fields. The dominant bacterial lineages varied between epibiotic and internal samples, with Sulfurovaceae, Desulfobulbaceae, Flavobacteriaceae, and Campylobacteraceae dominating in epibiotic samples, and Candidatus Thiobios affiliated with Chromatiaceae dominating in internal samples. Core microbial communities were mainly composed of Chromatiaceae, Sulfurovaceae, Desulfobulbaceae, and Flavobacteriaceae, and genera Desulfobulbus and Sulfurovum were found to be responsible for the dissimilarity between samples from different vent fields.

Summary: A mooring with sediment traps and a current meter was deployed near the Wocan hydrothermal field to study the variations in composition and flux of settling particles. The collected particles showed high content of hydrothermally derived minerals. The data indicate that the current direction, trap position, and height above the bottom have strong impacts on the observations of the hydrothermal fluxes.

Summary: The study investigated the speciation of Fe and distributions of Fe-binding ligands in hydrothermal plumes over high and low-temperature vents as well as over diffuse venting fields. The results showed variations in dissolved Fe/total Fe ratios between different vent sites and the importance of weaker ligands in stabilizing Fe. Organically complexed Fe constituted significant proportions of the DFe and Fe-Lab fractions in all plume samples.

Summary: Different submarine hydrothermal systems have diverse chemical compositions, leading to unique impacts on the ocean carbon cycle. Research indicates that organic carbon produced in hydrothermal vent areas differs from that in background seawater, suggesting distinct carbon synthesis pathways for vent microbes. Enhanced biological production in hydrothermal plumes demonstrates the importance of hydrothermal activities on carbon production in the deep ocean.

Summary: The Solomon Sea was found to have relatively low concentrations of aluminum and manganese compared to the Equatorial Undercurrent, but local enrichments were observed near coastlines possibly due to sediment scouring by strong currents. Fluxes of dissolved aluminum and total dissolved aluminum leaving the Solomon Sea can explain about three quarters of their respective budgets in the Equatorial Undercurrent, while fluxes of dissolved manganese and total dissolved manganese only account for about half of their respective budgets. These fluxes are highly variable over time and subject to uncertainty regarding the contributions of water masses from the Northern and Southern Hemispheres to the Equatorial Undercurrent.

Summary: Hydrothermal iron supply plays an important role in the Southern Ocean carbon cycle. The magnitude of its impact on export production depends on the estimation method used, with inverse helium modelling leading to a significant reduction. However, the observed anomalies and correlation with observations suggest that the spreading rate input scheme is more accurate.

Summary: Deep-sea hydrothermal venting is an important source of dissolved iron to the oceans. This study investigates the evolution of Fe isotopes in hydrothermal plumes, finding that the variation in plumes is related to the loss of particulate Fe-sulfides or Fe-oxyhydroxides, and the δ(56)dFe compositions in plumes increase during dispersal/dilution. The data demonstrate how Fe isotopes are transformed within a hydrothermal plume above arc volcanoes.

Summary: This study investigates the vertical resupply of dissolved iron (DFe) in the Ross Sea shelf and its impact on water-column DFe distributions. The results show that the major source of DFe comes from the benthos during winter months when katabatic winds drive sea ice formation. The study also suggests that the vertical resupply of DFe mainly occurs during mid-late winter and is sensitive to changes in the timing and extent of sea ice production.

Summary: The dispersal of dissolved iron from hydrothermal vents in the Trans-Atlantic-Geotraverse system is mainly controlled by physical processes and occurs predominantly in the colloidal phase. Fine-scale mixing near the seafloor and transport through fracture zones play important roles in the dispersal, leading to predominant westward dispersal away from the Mid-Atlantic ridge at a larger scale, while diapycnal mixing drives northward transport within the ridge axial valley. Coarse resolution ocean models often used to assess ocean iron cycling are not able to accurately reproduce the observed dispersal due to the omission of local topography and mixing.

Summary: This study investigates the seasonality of aluminum (Al) and manganese (Mn) sources in the Gulf of Alaska coastal region. It finds that sediment resuspension plays a significant role in delivering trace metals during the pre-stratification period, while meltwater becomes a major source of Al and Mn during spring and summer. The behavior of dissolved and particulate trace metals in coastal waters is controlled by different physical mechanisms.

Summary: The supply of iron to the surface ocean affects primary productivity, but the extent of iron input from hydrothermal sources in the deep ocean is poorly understood. This study examines the variability in dissolved iron to excess helium ratios at four hydrothermal vent sites along the Mid-Atlantic Ridge. The results show that the ratios differ due to differences in plume age, and the presence of particulates affects the ratio within a certain distance from the vents. The study highlights the need for further research on vent sources and their impact on iron flux in the deep ocean.
