Drawing as a tool for representing and explaining complex structures in Foraminifera
(Elsevier Masson SAS, 2025-12-29) Lería, María; Ferràndez i Cañadell, Carles
This work considers the relevance of drawing in foraminiferal micropaleontology and how drawing has helped to understand and explain the complex architecture of foraminiferal tests. We present a brief anthology of those works on foraminifera in which drawing plays a significant role. The objective is to detect milestones in the illustration of foraminifera throughout history and to explore a trajectory in the evolution of the drawing techniques and concepts applied. Drawing is influenced by technological advances, the artist’s skills, and the aesthetic influences of the moment. We conclude that drawing, a crucial aspect in this scientific discipline, facilitates the understanding and explanation of complex forms. The literature on foraminifera is replete with small gems of drawing art, sometimes created by artists, but other times by the same micropaleontologists who studied fossil material and described the species. This work highlights some of these drawings to analyse their creation process and to show their great artistic value.
Best-practice stochastic facies modelling from a channel fill turbidite sandstone analog (the 'Quarry outcrop', Eocene Ainsa Basin, NE Spain)
(American Association of Petroleum Geologists, 2006-07-01) Falivene Aldea, Oriol; Arbués, Pau; Gardiner, Andy; Pickup, Gillian; Muñoz, J. A.; Cabrera, Lluís
Using data from an outcrop characterization of a sandstone-rich turbidite channel fill (the so-called ‘‘Quarry outcrop’’ in the Ainsa basin), several stochastic facies models were constructed at bedscale resolution (cells 2.5 m [8 ft] wide and 0.05 m [2 in.] thick).
Several industry-standard reservoir-modeling algorithms were employed: truncated Gaussian simulation, sequential indicator simulation, multiple-point geostatistics, and object-based methods with varying degrees of complexity.
The degree of similarity (i.e., realism) between realizations and the outcrop characterization was quantified through the use of several responses: (1) static connectivity, (2) effective permeability, and (3) recovery efficiency from waterflood simulations.
Differences in the responses measured from the outcrop and facies models were observed: these are mostly algorithm related, instead of caused by soft data or different stochastic realizations. Differences increase greatly when the permeability of the heterolithic
packages and mudstone beds (Ht-M) decreases and reflect the methods’ ability to model the inclined and undulating Ht-M packages and beds that occur in the outcrop. These packages and beds can drape scours and sandstone beds with depositional topography
and pinch-outs, producing sandstone thinning and dead ends.
Object-based methods capable of introducing highly undulating Ht-M beds provided the most realistic models. Variogram-based and simple object-based methods failed to capture and reproduce the whole length of undulating beds.
Multiple-point geostatistics provided realizations with responses intermediate between variogram-based and simple object-based methods and the more successful advanced object-based methods. The conditioning-to-harddata capabilities of multiple-point geostatistics are higher than those of the object-based methods, which give them an added advantage.
Three-dimensional reconstruction of geological surfaces: An example of growth strata and turbidite systems from the Ainsa basin (Pyrenees, Spain)
(American Association of Petroleum Geologists, 2004-08-01) Fernández, Òsca; Muñoz, J. A.; Arbués, Pau; Falivene Aldea, Oriol; Marzo, M.
The external and internal geometry of four turbidite systems outcropping around the Buil syncline (Ainsa basin, Spanish Pyrenees) have been reconstructed with reservoir-scale resolution in three dimensions. The irregular geometry of the syncline and the resolution required for the reconstruction cannot be resolved with cross-sections. Therefore reconstruction has been carried out with a new methodology that applies a 3-D dip-domain geometrical model and 3-D restoration techniques to achieve reservoir-scale resolution in kilometric-scale reconstructions. This methodology is aimed at resolving 3-D geometries in folded areas, and regions with variable thickness stratigraphy.
The 3-D reconstruction of the Buil syncline reveals the synsedimentary growth of an intrabasinal anticline and the foreland lithospheric flexure associated to tectonic loading north of the Ainsa basin.
A FORTRAN program to introduce field-measured sedimentary logs into reservoir modelling packages
(Elsevier Ltd., 2006-11-01) Falivene Aldea, Oriol; Arbués, Pau; Howell, J.; Fernández, Òscar; Cabello López, Patricia; Muñoz, J. A.; Cabrera, Lluís
Building reservoir-scale facies models of outcrops is a practice that improves the three-dimensional geological modelling of subsurface analogues. Facies modelling of outcrops can be achieved either with geostatistical or object-based methods, which in most cases require conditioning to field-measured sedimentary logs. DEVLOGS assists in producing input files from field-measured sedimentary logs to be loaded into standard reservoir modelling packages. This is achieved by using a number of georeferenced nodes along the sedimentary log trace, and placing the intermediate bed boundaries according to true thickness recorded in the sedimentary log. Moreover a number of operations to enable the correct loading of the sedimentary logs are also performed. The main benefit of DEVLOGS is to facilitate the loading of non-vertical logs, by using non-vertical logs, the conditioning of outcrop models it is not limited to favourable outcropping settings such as very step exposures or non-dipping strata.
Hierarchical geocellular facies modelling of a turbidite reservoir analogue from the Eocene of the Ainsa basin, NE Spain
(Elsevier B.V., 2006-07-01) Falivene Aldea, Oriol; Arbués, Pau; Howell, J.; Muñoz, J. A.; Fernández, Òscar; Marzo, M.
Geocellular models of analogues can provide with insights into modelling strategies for the subsurface, therefore a model of the outcropping Ainsa turbidite system, deposited in slope setting, was built. The modelling began with a structural reconstruction mostly from outcrop data to remove structural relief. The facies modelling workflow consisted of three nested stages, each corresponding to a different scale. (a) The first scale addressed the deterministic reconstruction of surfaces that bound sedimentary bodies. (b) The second scale related to the modelling of the interfingering at the gradational boundaries of sedimentary bodies. (c) The third scale reproduced the internal heterogeneity within the sandstone-dominated bodies. Flow simulation revealed differences in recovery efficiency depending upon the scales of modelling considered.
New early Rupelian endemic porcellaneous larger foraminifera from the Prebetic Range, westernmost Tethys. Discussion on Praerhapydionina.
(Cushman Foundation for Foraminiferal Research., 2024-02-15) Ferràndez i Cañadell, Carles
Peneroplis peramplus n. sp. and Spirolinella emmae n. gen., n. sp. are described from the early Rupelian of the Ibi section in the Prebetic Range (southeastern Iberia). The former is a Peneroplis species of evolute annular growth with a large bilocular megalospheric embryo. Spirolinella n. gen. is similar to Spirolina, from which it differs by a complex aperture. Spirolinella is also similar to Praerhapydionina, but it completely lacks radial partitions. It also differs in the wall texture, homogeneous in Spirolinella and with a pseudokeriotheca-like texture in Praerhapydionina. This newly observed character in Praerhapydionina will help to identify the genus and verify its presumed cosmopolitan distribution. The two new species show the same stratigraphical range, corresponding to the Shallow Benthic Zone SBZ 21, early Rupelian, and are considered endemic to the carbonate platform that developed during the Paleogene in the southeastern margin of the Iberian plate, at the westernmost Tethys.
Macrolitter trapping in mangroves: Insights from forest structure and local community knowledge
(Elsevier B.V., 2025-12-18) Garcés Ordóñez, Ostin; Canals Artigas, Miquel; Romero, Diana; Thiel, Martin
Mangroves, globally recognized as critical coastal ecosystems, form fringe, basin, and riverine forests in tropical and subtropical coastal zones, where their aerial roots trap macrolitter carried by currents. This study provides the first large-scale integration of field surveys and community knowledge from 671 interviews to assess macrolitter sources, composition, and abundance in 29 mangrove sites in Colombia. We also examined relationships between macrolitter abundance and forest type (fringe, basin, riverine), species composition, tree density, basal area, and proximity to pollution sources. Residents emerged as the main contributors to mangrove macrolitter, largely because of poor waste management practices. Macrolitter abundance was significantly higher in fringe mangroves (2.5 ± 3.6 items m⁻²) compared to basin (0.3 ± 0.3 items m⁻²) and riverine (0.2 ± 0.1 items m⁻²) mangroves. Forest structural variables showed no significant effect on macrolitter abundance, whereas the distance to the nearest population center had a moderately significant effect. Plastics dominated across all mangrove types (89.6 %–93.1 %); floating items prevailed in fringe and riverine mangroves, whereas heavier materials (glass, metals, pottery) were more common in basin mangroves. These findings demonstrate that mangroves act as natural traps for macrolitter, regardless of forest composition or structure, and are heavily impacted by waste from nearby communities. The socio-ecological approach of this study underscores the urgent need to reform packaging for high-consumption products, improve waste management, and deepen community education as public policy priorities. Strengthening these measures would enhance mangrove conservation and support global agendas on coastal management and pollution mitigation.
From salt carapace to secondary minibasin encasement—The Bolon Secondary Minibasin, Eastern External Betics, SE Iberia
(Elsevier B.V., 2025-10-01) Canova, David P.; Roca i Abella, Eduard; Ferrer García, J. Oriol (José Oriol); Ferràndez i Cañadell, Carles; Escosa, Frederic O.; Afzal, Jawad
The Bolon Secondary Minibasin (BSM) evolved on the now eroded Elda Salt Sheet, which contains fragments of the diapiric roof and syn-contractional sediments. Our detailed analysis of the BSM reveals how diapir rejuvenation and salt sheet evolution can affect the structural and stratigraphic architecture of secondary minibasins. We present a comprehensive analysis of the BSM integrating detailed cartography with stratigraphic, paleontological, and structural data. The field data show that the BSM contains a carapace of latest Cretaceous marlstones overlain by an up to 800 m thick roof of terrigenous and outer platform deposits. These suprasalt deposits are characterized by tabular beds without diapir derived detritus and are cut by a series of extensional growth faults that sole into the salt. In the Oligocene, diapir rejuvenation due to contractional deformation resulted in the breaching and dismemberment of this diapiric roof and extrusion of allochthonous salt. Roof dismemberment is recorded as an unconformity truncating the roof strata and diapir derived detritus in the Oligocene-lower Miocene units. Throughout the middle Miocene composite halokinetic sequences, rapidly shifting depocenters, episodic unconformities, and stratigraphic onlaps record the rapid sinking and progressive northward rotation of the BSM. Debrite wedges, diapir derived detritus, and ramp-flat geometries along the upper salt-sediment contact show that in the middle Miocene the BSM was fully encased in allochthonous salt. Continued shortening and further extrusion of allochthonous salt rotated the BSM an additional 60° to the NW before its eventual grounding on subsalt strata.
Buccal dental-microwear and feeding ecology of Early Pleistocene Theropithecus oswaldi from Cueva Victoria (Spain)
(Elsevier B.V., 2020-03-17) Martínez, L.M.; Estebaranz, F.; Ferràndez i Cañadell, Carles; Romero, Ad.; Ribot, F.; Galbany i Casals, Jordi; Gibert Beotas, Lluís; Martínez Pérez-Pérez, Alejandro
Despite the scarcity of fossil specimens of Theropithecus oswaldi in Eurasia, its presence out of Africa attests to the great dispersal of this Papionini genus during the Early Pleistocene. In the present study, we analyze the buccal dental microwear of T. oswaldi (T. o. leakeyi) fossil specimens from Cueva Victoria (Southeastern Spain). This analysis is the first characterization of the feeding ecology of T. oswaldi in Europe. The buccal microwear pattern of the molar and premolar teeth of T. oswaldi from Cueva Victoria shows great similarities to that observed for the extant frugivorous forest-dwelling Mandrillus sphinx and mangabeys (Cercocebus sp.)—both species adapted to durophagous dietary habits—while significantly different from that observed for the gramnivorous Theropithecus gelada. These results suggest that T. oswaldi from Cueva Victoria could have exploited both hard-shelled fruits or seeds and succulent fruits from open and forested Mediterranean ecosystems.

Coralgal buildup in a mixed carbonate-siliciclastic succession of the upper Eocene Sant Martí Xic Formation (Orís, Vic, SE Ebro Basin, Spain)
((UB). (ICTJA). (IDEA). (UAB). (CSIC), 2025-09) Mancini, Alessandro; Brandano, Marco; Gaglianone, Giovanni; Mannetta, Domenico; Ferràndez i Cañadell, Carles
Coralgal buildups from the mixed carbonate siliciclastic succession of the upper Eocene Sant Martí Xic Formation (Orís, Vic, SE Ebro Basin, Spain) were studied. During the upper Eocene, the sedimentation in the Orís area was strongly influenced by global and local factors associated with the evolution of the Ebro Basin. The stratigraphic series in Orís shows first a transgressive sedimentary sequence characterized by floatstone to rudstone limestone with Discocyclina and Nummulites, which developed in a deeper and oligophotic environment and in a general context of humid climate conditions. The second sequence is formed by progradational deltaic deposits rich in Nummulites and developed under more arid climate conditions. Coralgal buildups occur interdigitated with these deltaic deposits forming two different lens-shaped bioherms that resulted in a coalescent buildup, with coral colonies sparse in a skeletal matrix of different grain-size. Corals grew in the mesophotic zone of the deltaic system affected by light fluctuations during periods of low siliciclastic input. The coralgal buildups of Sant Martí Xic Formation were thus influenced both by climatic changes and by the local detrital input from a deltaic system, associated with the uplift of the Catalan Coastal Range, highlighting the resilience of Eocene corals to environmental change.
Zipper tectonics in the Tyrrhenian-Apennines system: linking rift inheritance with thrusting, back-arc extension and crustal delamination
(Elsevier B.V., 2025-12-01) Tavani, S.; Maresca, A.; Carminati, E.; Cavinato, G.P.; Corradetti, A.; Granado, Pablo; Manatschal, G.; Muñoz, J. A.
We review geological and geophysical data across the Tyrrhenian back-arc basin–central Apennines fold and thrust belt system and incorporate them into a crustal-scale balanced cross-section. The section allows us to derive a kinematic reconstruction of the subduction-to-collision system over the past 25 Myr and illustrates how its evolution was driven by the interplay between slab rollback and the inherited rifted margin architecture of the subducted plate. Oceanic subduction and slab rollback initially led to the formation of the Liguro-Provençal backarc basin and the thin-skinned Liguride accretionary wedge. Around 20 Ma, soft collision began as Adria rifted margin arrived at the subduction zone; the buoyant continental crust docked at the subduction zone, causing the deceleration of both slab rollback and thrust propagation. During the subsequent 8 Myr of soft collision, thrusting occurred in a thin-skinned framework. By 12–10 Ma, the shift to hard collision caused the subduction interface to move into the ductile middle crust, triggering a decoupling of contractional deformation into thin- and thick-skinned tectonics. This also renewed slab rollback, initiated lower crust delamination, and accelerated thrust propagation toward the foreland and back-arc extension in the belt’s axial zone. Since then, deformation and seismicity have been driven by the forelandward migration of a singularity point within the lower crust, where contractional and extensional structures converge. Lower crustal delamination caused foreland-dipping lowangle normal faulting, culminating in the opening of the Tyrrhenian back-arc basin. This evolution is captured in a zip-like tectonic model, of which the Apennines provide a world-class example.
Geology of the Golobar and Rumaceo faults, Basque-Cantabrian Pyrenees
(Taylor & Francis, 2024-11-11) Carola i Molas, Eloi; Muñoz, J. A.
The lateral transition between different styles of deformation is crucial for understanding local-scale structures since it influences orogenic reconstructions at the crustal scale. This is especially important at the westernmost Basque-Cantabrian Pyrenees, where the transition from the thin-skinned Basque-Cantabrian Pyrenees to the thick-skinned Cantabrian Mountains remains a subject of debate. To address this, detailed geological mapping and proper fault characterisation are critical. This research focused on the surface characterisation of the Golobar Fault System, one of the faults located at the transition between the two styles of deformation. The results of this study include not only a detailed geological map of the Golobar Fault System but also its integration with neighbouring seismic sections and well data. This approach enhances the understanding of the deeper portions and lateral thickness variations, thereby providing a more comprehensive understanding of the Golobar area within the regional framework.
Surface and subsurface geology of the Hontomín structure, Western Pyrenees
(Taylor & Francis, 2025-08-11) Carola i Molas, Eloi; Roca i Abella, Eduard; Quintà Riera, Anna; Muñoz, J. A.
A detailed geological study was conducted in the Hontomín area in the western Pyrenees,Northern Spain, focusing on structural characterization by integrating available subsurfacedata with a newly developed surface geological map. It reveals a relatively simple surfacestructure, with the Upper Cretaceous generally dipping gently eastward, except at thesouthern margin, where they are deformed into tight E-W-trending folds. In contrast,the unconformable Cenozoic layers dip only a few degrees southward. However, seismicdata interpretation reveals a much more complex subsurface structure. It is dominatedby a broad dome, cored by Upper Triassic salt, which has significantly influenced theoverlying stratigraphy and structure. Above the salt, the Jurassic and Lower Cretaceousunits exhibit moderate folding, a deformation style that is not apparent at the surface.The deep structure is controlled by a major E-W trending thrust fault, which is notclearly expressed at surface except through small-scale, tight folds aligned in the samedirection. This study highlights the importance of integrating surface mapping withgeophysical data, both for accurately interpreting subsurface geology when planning forCO₂ injection operations.
New Workflow for Bridging the Gap Between Geology Knowledge and Society: The Example of the VIGEOCULT Project and the Orígens Geopark. South‑Central Pyrenees
(Springer, 2025-07-23) Puras, G.; Yagüe Medina, A.; Vallès, Jan; Muñiz, J.A.; Carola i Molas, Eloi; Muñoz, J. A.; Santolaria, Pablo; Gratacós Torrà, Òscar; Ferrer García, J. Oriol (José Oriol); de Matteis, Marco; Rivas, G.; Galobart, Àngel; Sellés, Albert; Dinarès Cabrerizo, O.; Mir Pellicer, X.
The effective dissemination of geological content in an engaging and easy-to-follow manner is challenging, especially because in most situations the general public has a limited geological background. This is particularly evident when considering dissemination outdoors. This study introduces a comprehensive workflow and methodology designed to transform complex geological research into accessible and engaging content for visitors to the Orígens UNESCO Global Geopark – hereinafter simply referred to as Orígens Geopark – in the southern Pyrenees. This workflow brings accurate geological research together with leading-edge graphical design techniques to create a set of outreach products such as virtual reality images, 3D models and 4D reconstructions of the past geological landscapes. Despite the potential of the workflow to create leading-edge dissemination products, some limitations have also been identified and are discussed here. This workflow developed for the project entitled “A natural open museum in the Pyrenees: virtual reality experience for dissemination and conservation of the geological and cultural heritage (VIGEOCULT) is applicable not only to Orígens Geopark but also in the tourism sector, educational (from elementary to university level) outreach in villages and schools, and public dissemination events.
Geology of the eastern tip of the El Tordell Fault, Southern Pyrenees
(Taylor & Francis, 2024-04-05) Carola i Molas, Eloi; Muñoz, J. A.
Along strike variations of frontal structures at fold and thrust belts allow us deciphering the evolution of contractional structures at early stages of deformation but also, how processes such as salt mobilisation, thrust emplacement, and folding develop. The external parts of the Pyrenees are suitable to investigate how these processes interacted during the Pyrenean Orogeny. The integration of fieldwork and subsurface data allowed us to obtain on the one hand the geological map of the eastern tip of the El Tordell Fault and the Súria Anticline and on the other hand, the 3D structural model of the study area. These two results allowed us to decipher the evolution of the area, which is characterised by the development, under compression, of a salt accumulation at early stages of deformation which was afterwards the locus of the El Tordell Thrust and finally, as deformation progressed, the development of the Súria Anticline.
New insights on the crustal deformation in the Eastern Betics from densified GNSS data
(Wiley, 2025-02-18) Portela, J.; Staller, A.; Béjar-Pizarro, M.; Martínez-Díaz, J. J.; Álvarez-Gómez, J. A.; Khazaradze, Giorgi
The Eastern Betic cordillera, southeastern Spain, is characterized by slow tectonic deformation rates and moderate seismicity. Great uncertainties persist regarding the precise kinematics of the main fault system within the region, the Eastern Betic Shear Zone (EBSZ). We present a new GNSS (Global Navigation Satellite System) velocity field in the Eastern Betics, including new episodic and continuous stations belonging to the GeoActiva network, as well as all available continuous stations in southern Iberia. We use this data to build kinematic models with elastic blocks, obtaining slip rates and locking ratios in the main faults of the EBSZ. Our model suggests that the central EBSZ is dominated by reverse and sinistral motion, accommodated by two fault branches closing the Guadalentín and Segura valleys. For the first time, we use geodetic data to quantify how slip is distributed between these branches in the central EBSZ: the Alhama de Murcia fault (western branch) accommodates up to 1.3 mm/yr sinistral and 0.6 mm/yr reverse slip, while the Palomares fault (eastern branch) is slower (0.5 mm/yr sinistral and 0.3 mm/yr reverse slip). Although slip rates are higher in the south Palomares and Carboneras faults, data scarcity limits their constraint. The deformation in the northern limit of the Eastern Betics appears to be distributed between the Jumilla and Crevillente faults. On a regional scale, our data suggest that the Nubia-Eurasia plate convergence is distributed radially from the Eastern Betics, consistent with the escape of multiple blocks driven by indentation and rollback tectonics in the Alboran Sea.
Spatial and temporal variability in blue carbon accumulation in the largest salt marsh in British Columbia, Canada
(Frontiers Media, 2025-11-18) Kohfeld, Karen E.; Basnayake, Hasini; Pellatt, Marlow G.; Olid Garcia, Carolina
Preserving blue carbon ecosystems, such as salt marshes, for climate change mitigation requires quantifying their carbon (C) dynamics. Boundary Bay (BB) marsh is a 222-ha salt marsh in southern British Columbia, Canada, where construction began in 2023 to enhance the marsh as a natural defense against coastal flooding. This study provides a baseline understanding of C storage and sequestration in Boundary Bay marsh prior to foreshore enhancement. We collected 18 sediment cores and vegetation surveys across the middle (BBM), eastern (BBE), and Mud Bay (MB) areas of the marsh, along with 128 depth profiles (i.e., field measurements of marsh thickness to refusal) from BBM. We combined C measurements with 210Pb chronologies, in addition to existing data from western Boundary Bay (BBW), to estimate C stocks (g C m-2) and accumulation rates (g C m-2 yr-1) for the entire marsh. Total C stocks averaged 71 ± 37 Mg C ha-1 for high marsh and 41 ± 36 Mg C ha-1 for low marsh, with higher values in western Boundary Bay (BBW, BBM) compared to the east (BBE, MB). Total C storage (Mg C) at Boundary Bay was 17,360 ± 4,960 Mg C, with the western marsh (BBW, BBM) comprising 84% of the total. The C accumulation rates (CAR) for Boundary Bay marsh averaged 80 ± 45 g C m-2 yr-1, comparable to regional averages on the Pacific coast of North America. However, large spatial variability exists, with significantly lower average CARs in the east (35 ± 11 g C m-2 yr-1). Historical aerial photographs indicate that the eastern marsh area (BBE, MB) decreased by ~35% while BBW expanded by ~20% since 1930. These contrasting trends suggest dynamism in marsh development, likely driven by environmental factors and human influence. This work highlights the high spatial and temporal dynamics of blue C ecosystems, especially in urban settings, and how decadal changes induced by human activities could influence their short-term (years to decades) C storage capacity, with potential consequences for long-term (centuries to millennial) C sequestration.

Increased Ecosystem Productivity Boosts Methane Production in Arctic Lake Sediments
(Wiley, 2025-07-01) Bulínová, M.; Rouillard, A.; Schomacker, A.; Kjellman, S.E.; Gudasz, C.; Olid Garcia, Carolina; Rydberg, J.; Panieri, G.; Hodson, A.; van der Bilt, W.G.M.; Røthe, T.O.; Bindler, R.
Global estimates of methane (CH4) emissions from lakes to the atmosphere rely on understanding CH4 processes at the sediment‐water interface (SWI). However, in the Arctic, the variability, magnitude, and environmental drivers of CH4 production and flux across the SWI are poorly understood. Here, we estimate CH4 diffusive fluxes from the sediment into the water column in 10 lakes in Arctic Scandinavia and Svalbard using porewater modeling and mass transfer estimates, which we then compare with 60 published estimates from the Arctic to the tropics. Diffusion of CH4 in the sampled lake sediments ranged from -0.46 to 3.1 mmol m-2 day-1, which is consistent with previous reports for Arctic and boreal lakes, and lower than for temperate and tropical biomes. Methane production occurs primarily within the top ∼10 cm of sediment, indicating a biogenic origin. Random forest predictive modeling of the sampled lakes revealed that condition promoting production and deposition of autochthonous organic carbon in Arctic lakes drive CH4 diffusion into the water column by fueling sediment CH4 production. For small lakes across biomes, determinants of the estimated CH4 flux were also best captured by climate predictors, with warmer and wetter conditions favoring ecosystem productivity and enhancing flux but also lake morphometry resulting in important regional variability in estimates. Our study emphasizes the importance of quantifying diffusive CH4 fluxes from sediments in diverse lake types to account for differences in the controls on primary production and the preservation of organic carbon across and within different biomes, to refine CH4 emission estimates in a
warming climate.
