    Corals living in naturally extreme environments such as mangrove lagoons have been considered as ‘super corals’ for reef conservation. However, this study shows that resistance in highly variable conditions comes with biological trade-offs that could compromise the suitability of these stress-tolerant corals for reef management under worsening climate change conditions.

    Turbulent pair dispersion is relevant for mixing processes such as microplastics transport in the ocean or dynamics of water droplets in clouds. The authors present a geometrical framework and empirical evidence that elucidate the universality of the process across scales, while forming a bridge with the classical Richardson theory.

    Petrels are wide-ranging, highly threatened seabirds that often ingest plastic. This study used tracking data for 7,137 petrels of 77 species to map global exposure risk and compare regions, species, and populations. The results show higher exposure risk for threatened species and stress the need for international cooperation to tackle marine litter.

    This study presents an absolute metabolic index that quantifies how ocean temperature, dissolved oxygen and organismal mass interact to constrain the oxygen budget an organism can use to fuel aerobic metabolism. The index is calibrated with physiological measurements from purple sea urchin and red abalone and the authors test if the index can delimit the distribution of these two species.

    In this study, the authors use a global dataset of satellite-derived shoreline positions, and demonstrate that their interannual evolution is dominated by El Niño through its worldwide influence of sea level, river discharge and ocean waves

    Seasonal stratification on the northwest European Shelf is found to be triggered by rainfall from passing storms. Further links are made between the onset of stratification to large-scale pressure changes in the North Atlantic.

    The Tara Pacific program and expedition focused on coral reefs across the Pacific Ocean and used a coordinated sampling effort to address questions at multiple scales using a common suite of samples. Here, we highlight some of the Tara Pacific achievements, discussing the benefits of long-duration sea expeditions for investigating a wide array of research questions within a selected ecosystem.

    Using data from the Tara Pacific expedition to investigate symbiont fidelity and patterns of gene expression across a thermal gradient, this study shows that Pocillopora corals have a three-tiered strategy of thermal acclimatization that is underpinned by host–photosymbiont specificity, host transcriptomic plasticity, and differential photosymbiotic associations under extreme warming.

    From profiling the gene expression of five coral species exposed to Stony Coral Tissue Loss Disease (SCTLD), this study finds signatures of in situ degradation of Symbiodiniaceae experiencing photosystem dysfunction. These results indicate that Symbiodiniaceae may be the target of initial SCTLD infection, which subsequently induces host responses and tissue loss.

    This global analysis reveals that artificial light from cities is associated with the disruption of synchronised egg release by corals. This situation could reduce coral reproductive health, hindering conservation efforts in the face of climate change and other anthropogenic impacts.

    The authors find that whether the Labrador Current transports its cold, relatively fresh, and well oxygenated waters towards the subpolar North Atlantic or the eastern American coast depends on large-scale forcing, partly driven by winds over the North Atlantic.

    Combining geological evidence and modelling, Crichton and others find life in the ocean Twilight Zone (200 m to 1000 m depth) is vulnerable to warming due to lower food supply. High emissions may lead to severe depletion and extinction in this habitat

    Is phosphorous a limiting factor for life on ocean worlds (e.g. Europa and Enceladus)? Calculated dissolved phosphate concentrations from a wide range of possible water-rock reactions suggest cell populations larger than those observed in Earth’s deep oceans could be supported.

    This study shows that the total energy loss of gravity currents has a non-linear dependence on the work required to keep sediment in suspension, highlighting the importance of large-scale mixing for the particulate transport of gravity currents.

    The capacity of coral reefs to keep pace with sea-level rise is central to their ability to continue to provide shoreline protection to vulnerable coastal communities. Here, the study shows that whereas restoration has the potential to minimize climate-change impacts, doing nothing will amplify them.

    By combining fisheries, nutrient, and carbon cycling data, this synthesis suggests that marine kelp forests, a dominant but often undescribed habitat, provide services with a potential value of $111,000/ha/year and a global yearly value of $500 billion.

    In contrast to the North Atlantic, the projected overturning circulation in the Nordic Seas increases throughout most of the 21st century in global climate model simulations. The Nordic Seas could therefore be a stabilizing factor in the future AMOC.

    Biological carbon pump pathways combine to transport organic carbon into the deep ocean. This study shows that sinking particles sequester 4 Pg C, active transport sequesters 1 Pg C, and subduction sequesters 0.8 Pg C in the California Current Ecosystem.

    Barents Sea shelf experienced >30 episodes of glaciation which scraped off layers of rocks and led to petroleum reservoirs exposed onto the seafloor. Today, such uncapped reservoirs produce strong fluxes of methane gas and oil into the ocean.

    Strong negative climatological air-sea interactions effectively damp warming over the eastern Indian Ocean, resulting in weakening of the winds therein. This, in turn, changes the strength of ocean currents, which is considered as the primary mechanism responsible for modulating warming patterns.

    The authors investigate marine heatwaves on the ocean bottom in the shallow waters surrounding North America. Relative to their surface counterparts, bottom marine heatwaves are often more intense, more persistent, and can occur independently.

    This study reports a dense, late summer phytoplankton bloom in the Southern Ocean that accumulated unusually high levels of organic matter and supported feeding hot spots for birds and whales. The authors show that this recurring open ocean bloom is driven by anomalies in easterly winds that push sea ice southwards and favour the upwelling of deep waters enriched in hydrothermal iron.

    Little is known about genetic heterogeneity within deep sea cold seep microbial populations. From examining 39 abundant microbial species identified in sediment layers below the sea floor and across six cold seep sites, this study reports that their evolutionary trajectories are depth-dependent and differ across phylogenetic clades.

    Temperature shapes the adaptation and composition of microbiomes, but whether their enzymes drive the thermal response remains unknown. Using an analysis of seven enzyme classes from worldwide marine microbiome data, this study shows that enzyme thermal properties explain microbial thermal plasticity and they are both finely tuned by the thermal variability of the environment.
