Peatland Contribution to Stream Organic Carbon Exports From a Montane Watershed

Journal of Geophysical Research Biogeosciences (2019)

Thomas Rosset Laure Gandois Gaël Le Roux Roman Teisserenc Pilar Durántez Jiménez

Abstract Mountains contain many small and fragmented peatlands within watersheds. As they are difficult to monitor, their role in the water and carbon cycle is often disregarded. This study aims to assess the stream organic carbon exports from a montane peatland and characterizes its contribution to the water chemistry in a headstream watershed. High frequency in situ monitoring of turbidity and fDOM were used to quantify respectively particulate organic carbon (POC) and dissolved organic carbon (DOC) exports at the inlet and outlet of a peatland over three years in a French Pyrenean watershed (1,343 m.a.s.l.). The DOC and POC signals are both highly dynamic, characterized by numerous short peaks lasting from a few hours to a few days. Forty‐six percent of the exports occurred during 9% of the time corresponding to the highest flows monitored at the outlet. Despite its small area (3%) within the watershed, the peatland contributes at least 63% of the DOC export at the outlet. The specific DOC flux ranges from 16.1 ± 0.4 to 34.6 ± 1.5 g m 2 year −1 . POC contributes 17% of the total stream organic carbon exports from the watershed. As the frequency of extreme climatic events is expected to increase in the context of climate change, further studies should be conducted to understand the evolution of underestimated mountainous peatland carbon fluxes and their implication in the carbon cycle of headwaters.

World Karst Spring hydrograph (WoKaS) database for research and management of the world’s fastest-flowing groundwater

Figshare (2019)

Tunde Olarinoye Tom Gleeson Vera Marx Stefan Seeger Rouhollah Adinehvand

World Karst Spring hydrograph (WoKaS) database is a compilation of karst spring discharge observations from across the globe. The database consist of over 400 spring discharge datasets which were collected from researchers, national hydrological databases and agencies in different countries and some of the datasets were digitized from published articles. The WoKaS database aims to serve as resourceful tool which will promotes large-scale karst hydrological studies, improves management, protection, process and comparative understanding of the karst aquifer systems.

Variability of the groundwater sulfate concentration in fractured rock slopes: a tool to identify active unstable areas

Hydrology and earth system sciences (2009)

Stéphane Binet Lorenzo Spadini Catherine Bertrand Yves Guglielmi Jacques Mudry

Abstract. Water chemical analysis of 100 springs from the Orco and the Tinée valleys (Western Italy and Southern France) and a 7 year groundwater chemistry monitoring of the 5 main springs were performed. All these springs drain from crystalline rock slopes. Some of these drain from currently active gravitational slope deformations. All groundwaters flowing through presently unstable slopes show anomalies in the sulfate concentrations compared to stable aquifers. Particularly, an increase of sulfate concentrations was observed repeatedly after each of five consecutive landslides on the La Clapière slope, thus attesting to the mechanical deformations are at the origin of this concentration change. Significant changes in the water chemistry are produced even from slow (mm/year) and low magnitude deformations of the geological settings. Pyrite nuclei in open fractures were found to be coated by iron oxides. This suggests that the increase of dissolved sulfate relates to oxidative dissolution of Pyrite. Speciation calculations of Pyrite versus Gypsum confirmed that observed changes in the sulfate concentrations is predominantly provided from Pyrite. Calculated amounts of dissolved minerals in the springs water was obtained through inverse modelling of the major ion water analysis data. It is shown that the concentration ratio of calculated dissolved Pyrite versus calculated dissolved gneiss rock allows us to unambiguously distinguish water from stable and unstable areas. This result opens an interesting perspective for the follow-up of sliding or friction dynamic in landslides or in (a) seismic faults.
