dc.description.abstract | A unique data set of suspended sediment transport from the Breelva, which drains the
Werenskioldbreen (Southwestern Spitsbergen), is reported for the period 2007–2012. This basin is
thoroughly described hydrologically, glaciologically, and chemically. However, until now there
was a lack of full recognition of mechanical denudation. This study extends the information
on quantitative suspended sediment load (SSL), amounting to 37.30–130.94 kt per year, and also
underlines the importance of its modification by high discharge events, triggered by intense snowmelt
or heavy rainfall. The large floods during the hydrologically active season transported even 83%
of the total SSL. The variability of the SSL is controlled by glacial storage and release mechanisms.
Particularly interesting is the second half of the hydrologically active season when intense rainfall
events plays a key role in shaping the sediment supply pattern. The main source of fine mineral
matter is the basal moraine, drained by subglacial outflows. Their higher mobilization occurs
when the hydrostatic pressure increases, often as a result of rainwater supply to the glacier system.
An increasing precipitation trend for Hornsund fjord region determines a positive trend predicted for
sediment flux. | pl_PL |
