Abstract Accelerated mass loss from the Greenland ice sheet leads to glacier retreat and an increasing input of glacial meltwater fjords coastal waters around Greenland. These high latitude ecosystems are highly productive sustain important fisheries, yet it remains uncertain how they will respond future changes in Arctic cryosphere. Here we show that marine‐terminating glaciers play a crucial role sustaining productivity fjord ecosystems. Hydrographic biogeochemical data two systems...
Summary Quantification of ecosystem services ( ES ) is an important step in operationalizing the concept for management and decision‐making. With exponential increase research, have become a ‘catch‐all phrase’, which some suggest has led to poorly defined, impractical ambiguous concept. An overview methods used quantification needed examine their scientific rigour provide guidelines selecting appropriate measures. We present systematic review 405 peer‐reviewed research papers address...
Much uncertainty exists about the vulnerability of valuable tidal marsh ecosystems to relative sea level rise. Previous assessments resilience rise, which marshes can adjust by sediment accretion and elevation gain, revealed contrasting results, depending on contemporary or Holocene geological data. By analyzing globally distributed data, we found that increases in parity with seemingly confirming previously claimed resilience. However, subsidence substrate shows a nonlinear increase...
Abstract During a one‐year period temporal and spatial variations in suspended sediment concentration (SSC) deposition were studied on salt freshwater tidal marsh the Scheldt estuary (Belgium, SW Netherlands) using automatic water sampling stations traps. Temporal found to be controlled by inundation. The initial SSC, measured above surface at beginning of inundation events, increases linearly with height high tide. In accordance this an exponential relationship is observed between time...
*Although silica (Si) is not an essential element for plant growth in the classical sense, evidence points towards its functionality a better resistance against (a)biotic stress. Recently, it was shown that wetland vegetation has considerable impact on biogeochemistry. However, detailed information Si uptake aquatic macrophytes lacking. *We investigated biogenic (BSi), cellulose and lignin content of 16 aquatic/wetland species along Biebrza river (Poland) June 2006 2007. The BSi data were...
We investigated long‐term trends (1965–2002) in dissolved inorganic nutrients the tidal part of Scheldt estuary (Belgium, The Netherlands). Annually averaged concentrations silicate (DSi), nitrogen (DIN), and phosphate (DIP) increased significantly until mid‐1970s, after which they declined linearly at rates 0.6, 2.9, 0.3 µmol L ‐ yr , respectively. This co‐occurred with a deterioration followed by restoration water column oxic conditions. Because differences reduction rate DSi (1.2% ), DIN...

[1] Feedback between vegetation growth, water flow, and landform is important for the biogeomorphic evolution of many landscapes, such as tidal marshes, alluvial rivers, hillslopes. While experimental studies often focus on flow reduction within static homogeneous vegetation, we concentrate acceleration around dynamically growing patches that colonize an initially bare landscape, with specific application to Spartina anglica, a pioneer intertidal flats. were placed in large-scale facility 16...
Abstract Heat is recognized as a natural tracer to identify the exchange of water between groundwater and surface compartment. One‐dimensional (1D) heat transport models have ability obtain quantitative estimates vertical fluxes through sediment matrix. Input these can come from temperatures observed in bed material rivers lakes. The upper thermal boundary condition at groundwater–surface interface affected by seasonal diurnal temperature variations. We hypothesize that effects transient...
The trade in soybean, an important animal feed product, exemplifies the environmental and socio-economic impact of global markets agricultural policy. This paper analyses increasing production soybean exporting countries (deforestation grassland conversion) as well importing regions (decrease permanent by substitution grass feed). Ecosystem services monetary values were used to calculate observed land use changes. is balanced against economic value trade. results prove that consumption...
Spatial self‐organisation of ecosystems is the process by which large‐scale ordered spatial patterns emerge from disordered initial conditions through local feedbacks between organisms and their environment. Such considered important for ecosystem functioning, providing increased productivity, resistance resilience against environmental change. Although has been found an increasing number ecosystems, it never shown so far aquatic river vegetation. Here we explore existence freshwater...
Abstract Silica is an essential element for marine life and plays a key role in the biogeochemistry of ocean. Glacial activity stimulates rock weathering, generating dissolved silica that exported to coastal areas along with meltwater. The magnitude export from large glacial such as Greenland Ice Sheet presently poorly quantified not accounted global budgets. Here we present data two fjord systems adjacent which reveal by meltwater relative other macronutrients. Upscaled entire Sheet, equals...
Abstract. The weathering of silicates is a major control on atmospheric CO2 at geologic timescales. It was proposed to enhance this process actively remove from the atmosphere. While there are some studies that propose and theoretically analyze application rock powder agricultural land, results field experiments still scarce. In order evaluate efficiency side effects Enhanced Weathering (EW), mesocosm experiment set up soil Belgium amended with olivine-bearing dunite ground two different...
