Abstract. Land planning projects aiming to maximize soil organic carbon (SOC) stocks are increasing in number and scope, often line with the objective reach neutrality by 2050. In response, a rising of studies assesses where additional SOC could be stored over regional global spatial scales. order provide realistic values transferrable beyond scientific community, providing targets accrual should consider timescales needed them, taking into consideration effects C inputs, type, depth on...
Coastal saltmarshes provide a range of ecosystem services, such as flood protection and carbon sequestration, but face rapid global losses. Managed realignment (MR) is an increasingly popular method to artificially recreate these habitats by reinstating tidal regimes reclaimed land. However, improve MR design, better knowledge the processes that control morphological evolution in natural needed. In this paper, we develop tools assist monitoring creek network towards dynamic equilibrium,...
Abstract Salt marshes deliver vital ecosystem services by providing habitats, storing pollutants and atmospheric carbon, reducing flood erosion risk in the coastal hinterland. Net losses salt marsh areas, both modelled globally measured regionally, are therefore of concern. Amongst other controls, persistence any one location depends on ability their substrates to resist hydrodynamic forcing at front, along creek margins vegetated surface. Where relative sea level is rising, elevation must...
Movement of organisms plays a crucial role in microbial ecology, yet little is known about how, when and at what speeds soil microorganisms move. Literature offers conflicting lines evidence, even regarding whether single-celled can move all under typical conditions. We review the literature on movement context physicochemical complexity, to establish its likelihood prerequisite Our focus spatial temporal scales relevant for microbiota (µm cm, seconds days), with particular...
Abstract The vulnerability of saltmarshes to lateral erosion at their margin depends on the local biogeomorphological properties substrate. In particular, 3D architecture pore and root systems is expected influence shear strength, with repercussions for wider‐scale stability saltmarshes. We apply X‐ray computed microtomography (μCT) visualize quantify subsurface structures in two UK Tillingham Farm, Essex (silt/clay rich substrate) Warton Sands (sand‐rich substrate), four types ground cover:...
Subsurface structures and especially the interactions between pores, roots other organic matter elements have a strong impact on ecosystem functioning. Yet despite recent progress in application of X-ray Computed Microtomography (µCT) to soil structure agricultural science, applications more complex heterogeneous substrates found natural soils, specifically wetland remain sparse. We apply µCT heterogenous develop robust segmentation method quantify live necromass. This approach significantly...
Saltmarsh restoration such as managed realignment (MR) projects often include excavation of simplified tidal creek networks to improve drainage and marsh functioning, but their design is based on limited evidence. This paper compares the morphological evolution in current MR UK with natural saltmarshes, order provide improved guidance. The was monitored for 2–20 years post-breach at 10 sites across by semi-automatically extracting 12 parameters from lidar. rates are linked initial tidal,...
Abstract Urban soils exhibit a wide diversity of properties that have no equivalent in other environments but are overwhelmingly perceived as degraded by decision makers. As result, their potential is not considered urban planning even though they can deliver range ecosystem services. This paper describes support tool for assessing soil services to land use planning. An overview existing methods provided has been detailed. Destisol, model developed specifically the context, presented detail....
Estimates of bed roughness used for predictions sediment transport are usually derived either from simple scalars the physical (i.e., ripple height or grain size) hydrodynamic length (Zo) based upon velocity gradient estimates in benthic boundary layer. Neither parameter accounts irregular features. This study re-evaluates relation between and using high-resolution seabed scanning inlet a shallow lagoon. The statistically-robust relationship, on 1D statistical analysis elevation at different...
Abstract Coastal wetlands provide crucial ecosystem services including flood protection and carbon storage, but are being lost rapidly worldwide to the combined effects of sea-level rise, erosion coastal urbanisation. Managed Realignment (MR) aims mitigate for these losses by restoring reclaimed land tidal influence. Data creek evolution is critical assess performance design strategies improve implementation practices. This data descriptor provides a dataset horizontal morphological systems...
Soil moisture is a main driver of soil organic matter dynamics and an important environmental variable in all models predicting changes carbon stocks from site to global scales. Despite this, the mechanisms determining response heterotrophic respiration remain poorly quantified, being represented most current cycle as simple empirical functions. Soils are extremely complex heterogeneous environments many properties observed at profile or plot scale are, fact, determined by microscale...

In response, a rising of studies assess SOC additional storage capacities over regional global spatial scales. order provide realistic values transferrable beyond the scientific community, capacity assessments should consider timescales which this might be reached, considering effects C inputs, type depth on dynamics.

Soils constitute a carbon reservoir that can help to mitigate climate change, or conversely accelerate greenhouse gas emissions if not managed properly. are heterogenous and dynamic systems, which physico-chemical properties impact their current soil organic (SOC) stocks capacity store more carbon. Land-use planning aiming preserve increase SOC should therefore be aware of the spatial repartition various types dynamics therein. This project aims map effect typology on vertical stocks,...
As highlighted by recent regulations in Europe and worldwide, the multifunctionality of soils their capacity to deliver services societies are increasing importance land planners decision makers. Soils provide multiple ecosystem (ES) including food production, biomass-energy contribution climate change regulation through carbon storage. These need be estimated visualised at relevant scales order improve consideration planning decisions.This project aims map interdependent bundles soil a...
