The Mississippian Derbyshire Carbonate Platform outcrops, in the Peak District in UK, host many mud mound complexes (Gutteridge, 1995). The one near the village of Monyash, in Ricklow Quarry, is one of the best for outcrop quality and accessibility. Fieldwork and petrographic study allowed recognising three facies associations in the complex. A basal tabular portion, five metres thick, consists of nodular packstone-rudstone beds with patches of clotted peloidal-leiolitic micrite boundstone, interbedded with tabular clotted peloidal-leiolitic micrite/fenestellid bryozoan boundstone mounds (FA 1). The overlying, dome-shaped, decametre-size mound complex core formed by lateral accretion of numerous dome-shaped, metre-size mounds. These consist of an association of fenestellid bryozoan/clotted peloidal-leiolitic micrite boundstone with radiaxial fibrous calcite cement (FA 2). The mound core is flanked by dipping beds characterized by clotted peloidal-leiolitic micrite/fenestellid bryozoan boundstone, passing downslope to skeletal packstone with brachiopods and crinoids (FA 3). Flank beds are transitional to the crinoid-rich packstone/grainstone-rudstone beds occurring laterally to the mound complex. Clotted peloidal-leiolitic micrite textures have been interpreted as originated from in-situ precipitation mediated by the presence of microbial mats on the sea floor (Pickard, 1996). Likely, the complex developed during a deepening of the depositional environment in a middle-ramp intraplatform setting, by microbial communities colonisation of the seafloor. Microbially-mediated in-situ precipitates were then occupied by brachiopods and bryozoans, forming mounds whose vertical growth was prevented by currents (FA 1). A further deepening of the environment allowed vertical growth and coalescence of dome-shaped mounds, which accreted to form the decametre-size core (FA 2). Flank beds (FA 3) developed as a result of the metre-scale mound complex core relief over the seafloor. The presence of inner ramp crinoidal grainstone beds onlapping the complex core and vadose cements on top of the mound complex reveal that mound growth was interrupted by a phase of relative sea-level fall and subaerial exposure. Preliminary evaluation of the diagenetic history through petrographic analysis shows a first phase of marine diagenesis (radiaxial fibrous calcite cement), followed by meteoric diagenesis (dissolution vugs, pendant vadose cement). During the following burial phase, mechanical compaction, cementation (blocky calcite cement), silicification and pressure solution occurred. Fissure formation was followed by precipitation of coarse late calcite cement. Finally, hydrocarbons and mineralising fluids pumped from adjacent basinal areas (e.g. Walkden &amp; Williams, 1991) opened fractures, stylolites and intercrystalline discontinuities. Presence of bitumen in the resulting fissures prevented the precipitation of further calcite cement, leaving open secondary porosity.

technical paper

The present geomorphology of the Volturno river delta and related strandplains is largely a product of an intricate long-term relationships between geological evolution and human impacts. In order to assess the main drivers of the changed landscape in the last 150 years, a multidisciplinary study was carried out by combining historical and geological data. A 150 year cartographic sources were acquired, georeferenced and managed into a GIS environment. Some 1800 well log stratigraphic data were acquired and interpreted to reconstruct the stratigraphic architecture of the plain. Historical analysis has produced documentary evidence of the geomorphological evolution of the area since the end of the XVII century, when, during the Spanish vice-kingdom, it was subjected to major land reclamation. More than 500 km of canals were built in the coastal area. The development of agriculture and farming on reclaimed land promoted urbanization and increasing landscape fragmentation. The peak was attained between the 1960s and the 1990s, when landscape pattern structure increased in complexity with major alterations of alluvial channels and of the deltaic environment, and retreat of the coastline. Land use maps were reconstructed for the 1957 and 2012. The overgrowth of the urban areas to the sea, coupled with intensification of agricultural and tourism activities, resulted in the loss of high quality ecosystems such as the humid coastal setting, the lacustrine/marshy back-dune area and, in most cases, also the beach-dune system. The negative sedimentary balance resulting from the reclamation works on the river courses, together with the interventions along the Volturno river basin, resulted in an accelerated and severe coastal erosion. Coastline displacement was calculated at 7 time points, showing timing and causes of trends and rates of variation. The anthropic impacts were compared with the subsidence trends previously assessed. The lack of an unequivocal correlation of the latter with agricultural land use and zootechnical farm location indicates that these human activities do not exert a significant impact on regional subsidence rates. On the contrary, a net overlay of the subsiding areas with the geological architecture was recognized and in particular with the areal distribution and thickness of deposits such as clayey silts, clays and peats. From geotechnical point of view, these soils can be classified as fine-grained soil (mostly clayey) with poor mechanical properties (high compressibility and low strength). Moreover, the inclusion of significant amount of peat and organic matter clearly reflects high values for the coefficient of secondary compression. The subsidence rates, coupled with the sea level rise due to climatic changes, increase the vulnerability of the coast to erosion, flooding and storm surge and aquifer salinization.

The changing geomorphology of the Volturno delta and coast (northern Campania, Italy): human influence and geological architecture

Shoreline variability is a key factor in coastal studies. In the last decades, remote sensing techniques have been widely applied and several algorithms for shoreline detection have been developed to extract the so called Satellite Derived Shorelines (SDS). Multispectral and hyperspectral satellites provide images covering large areas with high spatial and temporal resolution, allowing to perform a near real-time analysis of shorelines worldwide. There are several open source algorithms (e.g. SHOREX (Pardo-Pacual et al., 2012) and CoastSat (Vos et al., 2019)) for shoreline detection at sub-pixel level, using freely available multispectral images (Landsat and Sentinel constellations). However, open source applications for SDSs analysis using hyperspectral data are not yet available. Recently the Agenzia Spaziale Italiana (ASI), has launched the PRISMA mission (PRecursore IperSpettrale della Missione Applicativa), offering medium-spatial (30 m) and high spectral (smaller than 12 nm) resolution. In this study we present the performance of the CoastSat algorithm applied to multispectral images. Additionally, we show the capability of hyperspectral techniques applied to PRISMA images to detect the shoreline given their higher spectral resolution. The performance of the CoastSat algorithm was evaluated in two different microtidal beaches of the Italian Adriatic coast (Emilia-Romagna and Marche Regions): Punta Marina (PM) and Sirolo (SIR). The beach at PM is a typical intermediate fine-sandy beach, while SIR is a mixed coarse sand-gravel reflective beach. SDSs were compared to RTK-DGPS surveyed shorelines, measured following the upper limit of the swash zone, and with shorelines derived from a video monitoring station, after manual mapping on variance images. The shoreline derived from in-situ surveys were coincident with Landsat-5, Landsat-7 and Sentinel-2 satellite overpasses The influence on the identification of SDSs of the run-up extent and beach morphodynamic state was evaluated. The obtained RMSE ranges between ~ 6.5 and 14 m at both sites, indicating that the shoreline is effectively obtained from multispectral images at sub-pixel level. In addition, we analysed the shoreline derived from a PRISMA hyperspectral image of PM. We found that similar results can be obtained using hyperspectral images.

Performance of remote sensing algorithms for shoreline mapping under different beach morphodynamic conditions

The Mediterranean coastal areas have been recognized as the most sensitive regions to actual climate and environmental changes. The increased frequency, intensity, spatial extent, duration, and timing of storm events due to climate change can increase the susceptibility of low-lying coastal areas to seawater flooding. The impact of climate change is expected to be strong in areas characterized by severe anthropogenic disturbances. In this context, the understanding of the interaction between beach dynamics, human impact, benthic marine habitat and climate forcing appears crucial for scientists and coastal planners to evaluate coastal risks and to develop the best measures to mitigate them. This work aims to improve the knowledge of the short‐term effects of storm events on the coastline morphology of natural, microtidal, wave dominated beaches located in the western Mediterranean trough the images processing from the data of video monitoring system at Piscinnì beach (SW Sardinia). The morphodynamic states and the spatial shoreline variability of this natural beach has been assessed in our study, during two years of data acquisition, from August 2013 to August 2015 along a 0.3 km stretch of sandy beach. During this period severe storm events mainly related to south-westerly winds (about 50 km/h on average) were happened. For the evaluation of morphodynamic states we carried out forty-two time-exposure (timex) images from three hundred snapshot, with a frequency of 1Hz, of a single recording interval during the storm events, that allow us to understand the morphology of the shoreface (configuration of bars and troughs). For the spatial shoreline variability, we rectified and georeferenced a single snapshot from the day before, during, and two days after the storm event. These images has been loaded in a GIS software where the shoreline was mapped, and the results showed an erosion and a consequent accretion of the studied beach of about 20 m in two days after the event (SW wind and waves) as a result of the deposition of the Posidonia oceanica beach-cast litter. Another significant result is the clear reconfiguration of nearshore bars linked to the wave energy flux, calculated by the Copernicus Marine Environment Monitoring Service. A better knowledge of this morphological response induced by storm events is crucial for coastal managers to define beach management plans (for example beach cleaning practice), to prevent coastal risk and to understand the importance of seagrass berm deposition in the formation of natural Mediterranean beaches.

Short-term effects of storm events on the coastline morphology of a Mediterranean microtidal wave-dominated beach (Piscinnì, SW Sardinia)

A large Neogenic "Calcari a Lucina" deposit - i.e. hydrocarbons-rich cold seep carbonate -, reaching 40 m of thickness and several tens of meters of extension, crops out in the Crotone Basin (South Italy). It is composed of authigenic carbonate forming a facies referable to the conduits of gas/fluid, crosscutting early carbonate-cemented bioclastic and siliciclastic sediments definable as pavement facies. Conduits are commonly characterized by the accretion of meters thick thinly laminated and banded calcite and formed by the alternation of dark micritic laminae and clear crystalline layers. The micritic laminae are characterized by an autochthonous microbial peloidal to dendrolitic fabric, incorporating coprolites and planktonic foraminifera. In contrast the crystalline layers are characterized by microspar laminae and centimeters thick sparry crusts composed of prismatic zoned calcite crystals. The pavement facies is typified by foraminiferal bioturbated mudstone/wackestone gradually passing to mixed arenites as the increasing of the siliciclastic grains composed of quartz, plagioclase, phyllosilicates, aphanitic lithic grains, phaneritic rock fragments, and heavy minerals, all immersed into a micritic carbonate matrix, and indicating both sedimentary and crystalline basement source. The foraminiferal assemblage, characterized by almost exclusively by planktonic forms, and the relative proportion of sandy/silty grains, indicate a deep-water setting with occasional siliciclastic coarser sedimentary flows. A common chemosynthetic macrofauna composed of often articulated and in life-position Lucinids, Mytilids and Vesicomids bivalves, associated to tubeworms and gastropods, is commonly present into such sediments. The deposits of the pavement facies are commonly brecciated, possibly because the overpressure conditions established by the gas/fluid injection, and the displacive growth of the conduit deposits that crosscut the sediments, suggesting a very early cementation of the micritic matrix. Clasts of breccias are also later lined by primary fibrous to acicular isopachous to fan-shaped calcite cement. The high diversity of the heavy minerals in the mixed arenite deposits together with the presence of unstable (green amphibole) and moderately stable (epidote, garnet, sillimanite) heavy detrital species, indicates a burial depth comprised between 600 m and 2000 m during which a late diagenetic phase occurred. A pervasive neomorphic recrystallization of the carbonate grains and the precipitation of mosaic equant calcite cements, filling the remnant voids, took place during this phase.

Neogene seepage carbonate deposition in the Crotone Basin (South Italy), preliminary results

A complex set of feedback mechanisms has allowed our planet to stay habitable for most of its 4.5 billion years of evolutionary history. During this time, life has significantly influenced the surface redox state of our planet, impacting the diversity of minerals available, the planet's atmospheric composition and long term climate stability. While the coevolution of the geosphere and biosphere has been recognized for some time for some events and processes (for example the Great Oxidation Event), the extent and diversity of coupled life-planet processes remains unclear. In this talk I'll review the current knowledge regarding geosphere-biosphere coevolution, highlighting biological processes that have a significant planetary scale impact and might have played a key role in influencing Earth evolutionary trajectory and habitability.

Geosphere and Biosphere co-evolution through space and time

Microbes colonize some of Earth’s most extreme environments, sometimes providing refugees for symbionts and decomposers. The vesicles in porous basalt and basanite of deep-sea volcanoes support flourishing subsurface micro-ecosystems, which are part of the deep biosphere of the igneous oceanic crust. Despite the abundance and antiquity of cryptoendoliths in structural cavities of the oceanic crust, the evolution and ecology of these cryptic ecosystems remain mostly elusive. Here we report morphological and geochemical properties of microbial body fossils in rock samples collected from Vesteris Seamount during cruise MSM86 of MS Maria S. Merian in 2019. The highly porous basanites exhibit densely intergrown filamentous networks and laminated deposits on vesicle walls of probable biotic origin preserved as secondary minerals like manganese- or iron-oxides and others. Morphological evidence suggests the dominance of fungi among filamentous fossils, whereas basal coatings on internal vesicle walls resembling minute stromatolites are interpreted as remains of iron- or manganese-oxidizing chemolithoautotrophic bacteria. Hand samples, thin sections, and polished slabs of vesicular basanite also yielded in vivo fungal mycelia associated with globular, botryoidal, and dendritic stromatolites. The spatial relation and growth of fungal filaments upon a basal microbialite suggests a symbiotic-like relation of the supposably autotrophic bacteria and the heterotrophic fungi. Such association would explain the recent findings of a vital fungi community in the oceanic lithosphere.

Microbial communities carry out the core redox reactions that control biogeochemical cycles of elements and nutrients mainly thanks to enzymes that use transition metals as catalytic cofactors, suggesting a direct link with the environmental availability of those metals. As Earth’s biosphere and geosphere have coevolved over time, the availability of these metals has changed, influencing surface redox conditions as well as cycling of elements and volatiles, leading to new and more abundant reductant-oxidant pairs, probably impacting the evolution and distribution of metabolic processes and expanding the network of microbial metabolism. Electron transfer reactions are the common thread of the history of life from the very beginning, and the emergence of proteins capable of incorporating metals that facilitate redox reactions is the foundation of the strong link between biosphere and geosphere. The delivery of life’s relevant transition metals is controlled to a first order by tectonic processes. We present here geochemical and microbiological coupled analysis of data from over 250 geothermal locations globally. Our work aims to look for links between the delivery of biologically important transition metals to the surface through plate tectonics and microbial functional diversity. Our dataset reveals correlations between key microbial functions and differences in the delivery of the key metal cofactors to the surface of our planet. Understanding which processes determine the delivery of biologically important transition metals, and how these affect the distribution of microbial enzymes critical for biogeochemistry, will allow to shed light on the interaction between Earth’s geosphere and biosphere, opening new doors not only on better understanding our planet, but also on what are the characteristics to look for in a planet potentially suitable for life.

Linking plate tectonic settings and microbial functions on a global scale

Subduction zones are critically involved in recycling of volatiles and elements between the surface and planetary interior and play a key role in climate stability and planetary habitability. Both in the forearc and backarc regions the lithosphere is affected by the deformation induced by the plate movements, generally favouring lithosphere fractures formations and the widespread origination of deeply-sourced springs, hot or cold, that carry deep fluids and gases up to the surface. These fluids and gases originate from the subducting slab as well as from the interaction of the rising fluids and melting with the overlying crust, and generate "hot spots" of microbial diversity and activity driven by the sharp redox, geochemical and often thermal gradients. Given their direct connection with the subsurface, deeply-sourced springs can be used as a window into the deep to understand processes happening at depth. To be able to use deeply-sourced springs as conduits to the subsurface we need to be able to deconvolve the surface signals from the deep subsurface ones. Despite the abundance of studies looking at the microbiology of hot springs globally, there are relatively few studies linking microbial diversity to the underlying geological processes, and especially in the backarc regions information are scarce. Here we present data on the microbial diversity of the deeply sourced springs along the backarc of the volcanic complex of Puna, Argentina, and assess the extent of influence from surface processes of the spring communities. We conclude that surrounding soil and shallow subsurface microbial communities minimally contribute to the diversity of the deeply sourced fluids that thus represent key samples to investigate the deep continental subsurface.

Deeply-sourced springs microbial diversity: a window into the deep of the Earth 

Being at the boundary between marine and continental realms, marine caves are affected by wide environmental variability for the interaction of marine and continental waters; for this, they are natural laboratories for studying the effects of seasonal and long-term environmental variability also in the perspective of global changes. The first studies of benthic foraminifera from marine caves of the Mediterranean Sea have been carried out in the Gulf of Orosei in the context of a scientific project which started in 2014 and has continued to this day. They demonstrated that benthic foraminifera are very sensitive environmental proxies in these habitats, due to their high diversity and adaptability. The Bue Marino system is constituted by North, Middle and South Branch which join together close to the coast. The study of benthic foraminifera and sediment texture from surface samples, associated with parameters of bottom water, indicated that the Middle Branch was characterized by warmer, saltier and less oxygenated water than the rest of the cave, and by finer sediment with abundant vegetal debris, probably supplied from the mainland during strongly rainy periods (Romano et al., 2021). Then, it was reasonable hypothesizing that cave sediments, although deposited in enclosed environment, are reliable archives of past climatic changes. A 18 cm long sediment core, collected in 2018 in the Middle Branch, was studied for grainsize and benthic foraminifera in order to highlight evidence of temporal changes of environmental conditions and their causes. In the whole core, sediment texture was homogeneous, with prevailing sand and silt in similar proportions, while clay was less abundant and gravel nearly absent. Two hyaline (Ammonia inflata and A. tepida) and one agglutinated species (Eggerelloides advenus), dominated the assemblage, accounting for a total of 70-92%. A main change occurred along the core, at 11 cm depth, for the shift from an assemblage in the lower section with prevailing A. inflata, to another one where the highly opportunistic E. advenus and A. tepida dominated. Of these two assemblages, the latter was more similar to that recorded in the surface sample (0-2 cm), collected at the same sampling station, for the dominance of E. advenus, despite A. inflata slightly prevailed on A. tepida. It was interpreted as the result of a highly organically-enriched environment where opportunistic taxa benefited of abundant degraded organic material under low-oxygen conditions. The prevalence of the “indifferent” A. inflata in the lower core suggests less stressed conditions with minor supply of continental vegetal debris, probably due to less frequent and/or intense rainy episodes in past times.

Paleoecological reconstruction and modern analogues from foraminiferal proxies in the Middle Branch of Bue Marino Cave (Sardinia, Italy). Work in progress

Cold seep environments are often associated with chemosynthetic communities at the seafloor, reflecting the spatial distribution and magnitude of methane fluxes in the sediment underneath. Quantifying areal fluxes and rates of consumption via anaerobic oxidation of methane (AOM) is extremely important for better understanding the future response of the benthic filter to climate-induced ocean warming. Short-time-scale transient processes such as tides, seasonal bottom water temperature fluctuations are efficiently recorded in unsteady-state pore water profiles. However, to interpret the long-term trends in methane fluxes and controlling factors one needs to integrate this data with sedimentary proxies and conduct paleo-reconstructions. We present a case study from the SW Barents Sea at Leirdjupet Fault Complex, where active methane seepage has been observed in summer 2018 from 295 m to 350 m water depth and is associated with microbial mats and tubeworms. We discuss the modern seepage conditions based on pore water data and habitat maps generated through Object-Based Image Analysis (OBIA) classification, and discuss the history of seepage recorded in sediment cores. A new ROV survey conducted in June 2021 in the same area revealed a very different situation compared to 2018, consistent with the long-term reconstructions since Late Weichselian deglaciation.
