Standardising research on marine biological carbon pathways required to estimate sequestration at Polar and sub-Polar latitudes
-
Marine biological (‘blue’) carbon pathways are crucial components of the global carbon budget due to the ecosystem services they provide through the fixation of CO2 from the atmosphere. CO2 is removed from biosphere through long-term sequestration into seafloor sediments, removing it from the carbon cycle. Coincident with marine ice loss, little studied negative (mitigating) feedbacks to climate change are emerging in polar waters, which is important to quantify and comprehend. Understanding the mechanisms driving these pathways, that could lead to change, is a massive task and to ensure studies are comparable requires standardisation and prioritisation of future research. The expertise of scientists within the EU grant, Coastal ecosystem carbon balance in times of rapid glacier melt (CoastCarb), identified the 23 most important high latitude pathways through a modified Delphi scoring system. Metrics were selected as priorities for future research and for syntheses across broader geographic regions. The metrics with the highest importance scores also scored as the metrics that could be most readily standardised in the next five years. This review provides a definition and description of how each metric is measured, including its central role to blue carbon pathways. It also provides recommendations for standardisation, emphasising the requirement for modelling studies to scale from geographically limited regions where high-resolution data is available. Where methods cannot be standardised, cross calibration between methods is required to ensure reproducibility. An increasing use of remote sensing and innovative technologies will be necessary to scale measurements across this vast and remote region.

New insights on the Lower Ordovician linguliformean brachiopods of the Anglo-Brabant Massif and the Stavelot-Venn Inlier (Belgium)
-
The Lower Ordovician (Tremadocian) linguliformean brachiopods of the southeastern part of the Anglo-Brabant Massif are documented systematically for the first time. The material belongs to a single Belgian locality (La Roche-en-Brabant), situated in one of the few valleys that incise the Mesozoic-Cenozoic cover, and more precisely from the topmost part of the siliciclastic Mousty Formation (Tangissart Member). Here, minute, poorly diverse linguliformeans are associated with planktic graptolites (Rhabdinopora) and nileid trilobites (Platypeltoides). They consist of three species belonging to three genera (Obolidae and Elkaniidae), of which only Broeggeria is known with certainty, due to the poor preservation of the material. In the Belgian part of the Stavelot-Venn Inlier, the presence of linguliformean brachiopods within the Floian Les Plattes Member of the Ottré Formation, which were reported more than 150 years ago, remains unconfirmed. The genus Broeggeria, known from several Belgian Tremadocian localities, is a relic from the Cambrian brachiopod fauna. By the Tremadocian it is well established globally between the Low-Latitude and High-Latitude provinces. The Belgian assemblage has strong similarities with assemblages from Baltica reflecting the early Palaeozoic changing palaeogeography.

Designation of a Brazilian topotypic neotype for Dardanus pectinatus (Ortmann, 1892) and establishment of D. ctenodon sp. nov. for the East Atlantic hermit crab previously misidentified with it (Crustacea, Decapoda, Anomura, Diogenidae)
-
The type locality of the hermit crab, Pagurus striatus var. pectinata Ortmann, 1892, as given in its original description, is Brazil. After its original brief taxonomic account, the species was first treated as amphi-Atlantic and later the name Dardanus pectinatus (Ortmann, 1892) was systematically applied to an African Atlantic species. No explicit reason has ever been given for this application. However, it transpires from the literature that carcinologists believed that the gastropod shell, Tonna galea (Linnaeus, 1758), occupied by the holotype of Pagurus striatus var. pectinata Ortmann, 1892 was endemic to the Mediterranean and Eastern Atlantic, and that the specimen had therefore been mislabelled. In fact, Tonna galea is amphi-Atlantic and the shell occupied by the hermit crab cannot be used to argue that it has been mislabelled. The holotype of Pagurus striatus var. pectinata Ortmann, 1892 is lost and its original description and illustration are insufficient to establish its true identity. Two steps are taken to stabilise the nomenclature in accepting the hypothesis by far most likely, i.e. that the holotype of Pagurus striatus var. pectinata did indeed come from Brazil. First action: a Brazilian neotype is designated for Pagurus striatus var. pectinata, with a specimen of a species compatible with its original description, namely Dardanus insignis (de Saussure, 1857). As a result of this action, Dardanus pectinatus (Ortmann, 1892) becomes a junior synonym of Dardanus insignis (de Saussure, 1857). Second action: the African Atlantic species is described as a new species, Dardanus ctenodon sp. nov., with a holotype from Senegal. The three similar Atlantic species Dardanus arrosor (Herbst, 1796), Dardanus ctenodon sp. nov. and Dardanus insignis (de Saussure, 1857) are the subject of an illustrated taxonomic account and an identification key is given for all the Atlantic species of Dardanus.

A description of existing operational ocean forecasting services around the globe
-
Predicting the ocean state in support of human activities, environmental monitoring, and policymaking across different regions worldwide is fundamental. To properly address physical, dynamical, ice, and biogeochemical processes, numerical strategies must be employed. The authors provide an outlook on the status of operational ocean forecasting systems in eight key regions including the global ocean: the West Pacific and Marginal Seas of South and East Asia, the Indian Seas, the African Seas, the Mediterranean and Black Sea, the North East Atlantic, South and Central America, North America (including the Canadian coastal region, the United States, and Mexico), and the Arctic. The authors initiate their discussion by addressing the specific regional challenges that must be addressed and proceed to discuss the numerical strategy and the available operational systems, ranging from regional to coastal scales. This compendium serves as a foundational reference for understanding the global offering, demonstrating how the diverse physical environment – ranging from waves to ice – and the biogeochemical features besides ocean dynamics can be systematically addressed through regular, coordinated prediction efforts.

A description of ocean forecasting applications around the globe
-
Operational oceanography can be considered the backbone of the blue economy: it offers solutions that can support multiple UN Sustainable Development Goals by promoting the sustainable use of ocean resources for economic growth, livelihoods and job creation. Given this strategic challenge, the community worldwide has started to develop science-based and user-oriented downstream services and applications that use ocean products as provided by forecasting systems as main input. This paper provides examples of stakeholder support tools offered by such applications and includes sea state awareness, oil spill forecasting, port services, and fishing and aquaculture. Also emphasized is the important role of ocean literacy and citizen science to increase awareness of and education about these critical topics. Snapshots of various applications in key world ocean regions, within the framework of the OceanPrediction Decade Collaborative Centre (DCC), are illustrated, with emphasis given on their level of maturity. Fully operational examples can be used as inspiration for export to other areas.

Limits of calcium isotopes diagenesis in fossil bone and enamel
-
Diagenesis has been recognized for decades to significantly alter the trace elements biogenic signatures in fossil tooth enamel and bone that are routinely used for paleobiological and paleoenvironmental reconstructions. This signature is modified during diagenesis according to a complex continuum between two main processes, addition and substitution. For an additive-like, or early diagenesis, the trace elements biogenic profiles can be restored by leaching secondary minerals, but this technique is inefficient for a substitutive-like, or extensive diagenesis for which secondary trace elements are incorporated into the biogenic mineral. This scheme is however unclear for Ca, the major cation in tooth enamel and bone hydroxylapatite, whose stable isotope composition (δ44/42Ca) also conveys biological and environmental information. We present a suite of leaching experiments for monitoring δ44/42Ca values in artificial and natural fossil enamel and bone from different settings. The results show that enamel δ44/42Ca values are insensitive to an additive-like diagenesis that involves the formation of secondary Ca- carbonate mineral phases, while bone shows a consistent offset toward 44Ca-enriched values, that can be restored to the biogenic baseline by a leaching procedure. In the context of a substitutive-like diagenesis, bone exhibits constant δ44/42Ca values, insensitive to leaching, and shows a REE pattern symptomatic of extensive diagenesis. Such a REE pattern can be observed in fossil enamel for which δ44/42Ca values are still fluctuating and follow a trophic pattern. We conclude that Ca isotopes in fossil enamel are probably not prone to extensive diagenesis and argue that this immunity is due to the very low porosity of enamel that cannot accommodate enough secondary minerals to significantly modify the isotopic composition of the enamel Ca pool.

How atmospheric forcing resolution impacts storm surge model results: Insights from Storm Xaver in the North Sea-Scheldt estuary continuum
-
Estuaries are particularly vulnerable to flooding from storm surges, a risk worsened by climate change. While numerical models are essential for flood risk management, most storm surge models rely on atmospheric forcing data with coarse spatial (tens of kilometers) and temporal (hours) resolutions—significantly lower than the model’s own grid resolution. This mismatch may compromise prediction accuracy. This study evaluates the impact of the spatial and temporal resolution of atmospheric forcing data on storm surge modeling within the Scheldt river-estuary-North Sea continuum for the record-breaking Storm Xaver (December 2013). Atmospheric forcings were incorporated at spatial resolutions ranging from 2 km to 30 km and at temporal resolutions from 15 min to 6 h. Using an unstructured-mesh multiscale hydrodynamic model, we assessed how these variations influenced the accuracy of storm surge simulations. Our findings indicate that spatial resolution has the greatest influence on model performance, with finer resolutions (2–5 km) improving peak surge predictions in estuarine areas. Temporal resolution enhancements provide additional benefits, but only when combined with high spatial resolution. The impact of temporal refinement diminishes rapidly as spatial resolution coarsens beyond 10 km. Notably, the timing of peak surges remains stable across all resolution combinations. The best results are obtained with 2 km and 15 min atmospheric forcing resolution, while 5 km spatial resolution also shows good performance. This study underscores the importance of aligning atmospheric forcing resolution with the hydrodynamic model’s spatial scale to achieve optimal accuracy in storm surge predictions within this estuary.
