Trends in Oil Spill Modeling: A Review of the Literature

Oil spill simulation models are essential for predicting the oil spill behavior and movement in marine environments. In this study, we comprehensively reviewed a large and diverse body of peer-reviewed literature obtained from Scopus and Web of Science. Our initial analysis phase focused on examining trends in scientific publications, utilizing the complete dataset derived after systematic screening and database integration. In the second phase, we applied elements of a systematic review to identify and evaluate the most influential contributions in the scientific field of oil spill simulations. Our analysis revealed a steady and accelerating growth of research activity over the past five decades, with a particularly notable expansion in the last two. The field has also experienced a marked increase in collaborative practices, including a rise in international co-authorship and multi-authored contributions, reflecting a more global and interdisciplinary research landscape. We cataloged the key modeling frameworks that have shaped the field from established systems such as OSCAR, OIL-MAP/SIMAP, and GNOME to emerging hybrid and Lagrangian approaches. Hydrodynamic models were consistently central, often integrated with biogeochemical, wave, atmospheric, and oil-spill-specific modules. Environmental variables such as wind, ocean currents, and temperature were frequently used to drive model behavior. Geographically, research has concentrated on ecologically and economically sensitive coastal and marine regions. We conclude that future progress will rely on the real-time integration of high-resolution environmental data streams, the development of machine-learning-based surrogate models to accelerate computations, and the incorporation of advanced biodegradation and weathering mechanisms supported by experimental data. These advancements are expected to enhance the accuracy, responsiveness, and operational value of oil spill modeling tools, supporting environmental monitoring and emergency response.

Microbiomes for a Stable Planet: Embedding Microbial Processes in Global Climate Action

Microorganisms regulate key biogeochemical processes and ecosystem feedbacks to climate change, yet they remain underrepresented in global environmental policy and implementation frameworks. The World Microbiome Partnership (WMP) Environment and Climate Change Roadmap sets out a coordinated agenda to embed microbial science into climate mitigation, adaptation, and nature-based solutions. It identifies three scientific priority actions: (i) microbial process accounting, (ii) global integration of microbiome data, and (iii) the deployment of microbiomes for ecological resilience. These priorities define the core knowledge and governance gaps that currently limit the effectiveness of climate mitigation, adaptation, and nature-based solutions. To operationalise these priorities, the Roadmap establishes interoperable microbiome data infrastructures linking distributed observations across biomes, a federated governance model combining regional stewardship with global standards, and measurable microbial indicators translated into policy-relevant targets for climate, biodiversity, and ecosystem rehabilitation. The roadmap proposes alignment with existing climate and biodiversity agreements to avoid duplication and maximise impact. By articulating concrete near-term priorities and cross-sector partnerships, this comment aims to catalyze coordinated investment and action so that microbial systems are recognized, protected, and harnessed as essential components of a stable and just climate future.

Carbon sequestration service in the Atlantic Ocean: an assessment from coastal to ocean ecosystems

The ocean plays a central role in the global carbon cycle. It regulates atmospheric CO₂ through long-term sequestration in coastal and deep-sea systems. Blue Carbon Ecosystems (BCEs)—mangroves, salt marshes, seagrass meadows, and tidal flats—are recognized for their high carbon burial efficiency per unit area and their growing relevance in climate policy. In contrast, the open ocean, driven by the Biological Carbon Pump (BCP), dominates large-scale carbon storage but is rarely considered alongside coastal systems in carbon budget assessments. Here, we present a basin-scale assessment of carbon sequestration across the Atlantic coastal and open-ocean domains. To do so, we quantified carbon fluxes and long-term stocks by harmonizing and integrating spatial datasets, Earth System Model outputs, and a data-assimilated biogeochemical framework. Coastal ecosystems show high sequestration efficiency per unit area. The open ocean, however, accounts for most of the total carbon storage due to its depth, extent, and circulation-driven redistribution of remineralized carbon. By creating a unified framework that allows to combine coastal burial processes with pelagic carbon transfer in a consistent way, this study clarifies how different definitions of sequestration shape basin-scale estimates. The results provide a robust basis for improving representation of marine carbon processes in regional and global carbon budgets, marine conservation strategies, and climate mitigation planning.
