This study examines the suitability of authigenic 10Be/9Be dating method to deposits an incising river, taking as example Nová Vieska river terrace, which accumulated during neotectonic inversion Danube Basin (western Slovakia). The succession was formed by a wandering with minor preservation proximal floodplain muds. frequent occurrence mud intraclasts reflects significant input eroded materia...

Abstract ABSTRACT: The abyssal overturning circulation is thought to be primarily driven by small-scale turbulent mixing. Diagnosed watermass transformations are dominated rough topography “hotspots”, where the bottom-enhancement of mixing causes diffusive buoyancy flux diverge, driving widespread downwelling in interior—only overwhelmed an even stronger up-welling a thin Bottom Boundary Layer ...

Hydrochemical and geophysical data collected during a hydrological survey in September 2017, reveal patterns of small-scale connectivity small water track catchment the north-European Arctic. The stable isotopic composition different compartments was used as tracer processes at scale. Elevated tundra patches underlain by sandy loams were disconnected from stream stored precipitation previous mo...

GLORIA sidescan imagery, multibeam bathymetry, seismic profiles, and piston cores (3-5 m penetration) reveal the near-surface geology of the Bryant Canyon turbidite pathway on the continental margin of Louisiana. This pathway extends from the continental shelf edge, across the continental slope, to a deep-sea fan on the continental rise. The pathway is narrow (<2 km) where it crosses shallow sa...

In order to qualify and quantify the impact of sediment contamination in hydric settings by metallic trace elements (MTE) emanating from controlled dump Fez city (northern Morocco), leachate sample analyses were carried out. The leachates collected 24 sites are characterised a pH between 6.91 8, COD varying 430.7 7962 mg/L, an NTK content up 1955 with average 1514 nitrate concentration reaching...

Submarine canyons that incise continental slopes are considered an important conduit for transport of suspended matter between shelf seas and deep-ocean. However, the exact mechanisms influencing deposition still largely unknown. We present moored observations current flows, acoustic echo intensity and, in high-resolution, temperature variation from two contrasting mooring sites 6.5 km apart ho...

Although previous research has documented well-organized interactions between the turbulent flow field and an irregular boundary, the spatial variability of turbulent flow characteristics at the reach-scale remains poorly understood. In this paper, we present detailed field measurements of three-dimensional flow velocities and turbulence intensities in a high-gradient, cobble-bed riffle from th...

Morphological and sedimentological responses of streams to basin-scale impact have been well documented for intensively agricultural or urban areas. Sensitivity thresholds of streams to modest levels of disturbance, however, are not well understood. This study addresses the influence of forest conversion on streams of the southern Blue Ridge Mountains, a region that has received little attentio...

The long-term increases in average temperature and intensification of droughts which characterise the current state Earth’s climate system have a negative impact on forest ecosystems can lead to decrease their area deterioration living conditions components. In Ukrainian Steppe an important environmental, antierosion, water-protective soil-protective role belongs ravine forests. most valuable c...

This review and synthesis weaves various multiproxy data into a single coherent narrative for the latest Pleistocene–Holocene paleoclimatic paleoceanographic evolution of Black Sea, Marmara Sea Aegean Sea. narrative, referred to as “Outflow Hypothesis” rests on several key observations interpretations which are incompatible with suggestion that post-LGM reconnection basin global ocean occurred ...
