- •
Organic matter quantity, quality and sources were spatially and seasonally examined.
- •
Well-marked glacier-outer fjord quantitative gradients of OM throughout all seasons
- •
Spring events of surface primary production well recorded in sediments
- •
Discrepancy between quantity and quality of the sedimentary OM within the fjord
- •
Biogenic gradients influenced the prokaryotic distribution in the sediments.
- •
Spatial variability prevailed over seasonal variability in Kongsfjorden's sediments.
