Abstract The number and refinement of gridded meteorological datasets are on the rise at global regional scales. Although these now commonly used for hydrological modeling, representation precipitation amount timing is crucial to correctly model streamflow. Génie Rural à 4 paramètres journalier (GR4J) conceptual combined with CEMANEIGE snow routine was calibrated using four temperature [Système d’analyse fournissant des renseignements atmosphériques la neige (SAFRAN), Mesoscale Analysis...
In this paper, we outline the need for a coordinated international effort toward building of an open-access Global Ocean Oxygen Database and ATlas (GO 2 DAT) complying with FAIR principles (Findable, Accessible, Interoperable, Reusable). GO DAT will combine data from coastal open ocean, as measured by chemical Winkler titration method or sensors (e.g., optodes, electrodes) Eulerian Lagrangian platforms ships, moorings, profiling floats, gliders, ships opportunities, marine mammals, cabled...
The benthic environment is a crucial component of marine systems in the provision ecosystem services, sustaining biodiversity and climate regulation, therefore important to human society. With contemporary increase computational power, model resolution technological improvements quality quantity data, it necessary ensure that are appropriately represented coupled benthic-pelagic biogeochemical ecological modelling studies. In this paper we focus on five topical challenges related various...
Abstract. Constraining the mechanisms controlling organic matter (OM) reactivity and, thus, degradation, preservation, and burial in marine sediments across spatial temporal scales is key to understanding carbon cycling past, present, future. However, we still lack a detailed quantitative of what controls OM consequently, general framework that would allow model parametrization data-poor areas. To fill this gap, quantify apparent (i.e. degradation rate constants) by extracting reactive...
Abstract. Total alkalinity (AT) and dissolved inorganic carbon (CT) in the oceans are important properties with respect to understanding ocean cycle its link global change (ocean sinks sources, acidification) ultimately finding carbon-based solutions or mitigation procedures (marine removal). We present a database of more than 44 400 AT CT observations along basic ancillary data (spatiotemporal location, depth, temperature salinity) from various regions obtained, mainly framework French...
Abstract. River deltas are particularly important in the marine carbon cycle as they represent transition between terrestrial and carbon: linked to major burial zones, reprocessing zones where large fluxes can be mineralized. In order estimate this mineralization, sediment oxygen uptake rates were measured continental shelf sediments river prodelta over different seasons near outlet of Rhône Mediterranean Sea. On a selected set 10 stations nearby shelf, situ diffusive (DOU) laboratory total...
Abstract. The Rhône River is the largest source of terrestrial organic and inorganic carbon for Mediterranean Sea. A large fraction this either buried or mineralized in sediments close to river mouth. This mineralization follows aerobic anaerobic pathways, with a range impacts on calcium carbonate precipitation dissolution sediment near sediment–water interface. study focuses production dissolved (DIC) total alkalinity (TA) by early diagenesis, consequential pH variations effect dissolution....
Abstract. Observations indicate that resuspension and associated fluxes of organic material porewater between the seabed overlying water can alter biogeochemical dynamics in some environments, but measuring role sediment processes on oxygen nutrient is challenging. A modeling approach offers a means quantifying these for range conditions, models have typically relied simplifying assumptions regarding seabed–water-column interactions. Thus, to evaluate dynamics, we developed coupled...
