    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.

    Here the authors show that Chinstrap penguins play a significant role in iron recycling, essential for phytoplankton growth and carbon sequestration, recycling yearly 521 tonnes of iron, half of what they did 40 years ago due to population decline.

    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.

    Estimating the amount of plastics that enters the ocean is subject to significant uncertainty. This study uses ocean plastic abundance data to refine our estimate and reduce this uncertainty, enabling more effective control and mitigation polices.

    Based on two high-resolution simulations, the authors find that submesoscale eddies significantly boost poleward oceanic heat transport in Antarctic waters by strengthening transport capability of mesoscale eddies through inverse energy cascade.

    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.

    Marine fishes can substantially contribute to the inorganic carbon cycle through the excretion of intestinally precipitated carbonates, but the underlying drivers remain largely unknown. This study identifies the environmental factors and fish traits that predict carbonate excretion rate and mineralogical composition in tropical reef fishes.

    Ziveri et al find calcifying phytoplankton dominate pelagic CaCO3 production, but a large portion of this CaCO3 dissolves in the photic zone - they suggest the processes driving shallow CaCO3 dissolution are key to understanding the role of planktonic calcifiers in regulating atmospheric CO2.

    Zooplankton are a critical link to higher trophic levels and play an important role in global biogeochemical cycles. This Review examines key responses of zooplankton to ocean warming, highlights key knowledge and geographic gaps that need to be addressed, and discusses how better use of observations and long-term zooplankton monitoring programmes can help fill these gaps.

    Sharks and rays are vital coral reef species. This study shows that nearly two thirds (59%) of the 134 coral-reef associated species are threatened with extinction. The main cause of their decline is found to be overfishing, both targeted and unintentional, and extinction risk is greater for larger species found in nations with higher fishing pressure and weaker governance.
