Distribution of recent Benthic foraminifera in Kongsfjorden and Krossfjorden; North-West Svalbard, High Arctic
نویسندگان
چکیده
Benthic foraminifera assemblages from two fjords of Svalbard—Kongsfjorden and Krossfjorden in the High Arctic—have been studied. The show three characteristic fjords’ glacial proximal, middle distal parts. Cassidulina reniforme– Elphidium clavatum, Textularia spp. assemblage dominates fauna near glacier proximal that indicates increased sedimentation meltwater runoff; a Nonionellina labradorica– Islandiella helenae– Lobatula lobatula relates to well-oxygenated high energy conditions mainly occupies part; helenae dominate region surface primary productivity. contains an oxygen deficiency zone around part characterised by Stainforthia loeblichi. abundance labradorica productivity is more than Kongsfjorden.

Diversity and distribution of fungal communities in the marine sediments of Kongsfjorden, Svalbard (High Arctic)
This study assessed the diversity and distribution of fungal communities in eight marine sediments of Kongsfjorden (Svalbard, High Arctic) using 454 pyrosequencing with fungal-specific primers targeting the internal transcribed spacer (ITS) region of the ribosomal rRNA gene. Sedimentary fungal communities showed high diversity with 42,219 reads belonging to 113 operational taxonomic units (OTUs...
متن کاملBenthic foraminifera in Hornsund, Svalbard: Implications for paleoenvironmental reconstructions
Modern hydrology of a typical Arctic fjord (Hornsund, SW Spitsbergen, Sval− bard) was investigated and compared with commonly used in paleoceanography proxies: benthic foraminiferal assemblages and their stable isotope ( 18O and 13C) composition. The benthic foraminifera from Hornsund comprised 45 species and 28 genera. Their spatial variations follow the zonation pattern, resulting from the in...

The spatial distribution of benthic foraminiferal assemblage of Nayband Bay and Haleh Estuary in the North-West of the Persian Gulf, was explored during 2011-2012 . The relationship between spatial pattern of foraminifera assemblages and the ambient factors (i.e. water temperature, salinity, pH, dissolved oxygen, sediment grain size distribution, sediment organic content, and CaCO3 concentrati...

متن کاملMonothalamous foraminifera from West Spitsbergen fjords, Svalbard: a brief overview
During the 2004 summer season, 14 sediment samples were collected in Kongs− fjorden and Isfjorden, West Spitsbergen, from 6 down to 345 m water−depth (mwd). The samples yielded abundant assemblage of monothalamous foraminifera, belonging to almost 40 morphotypes. Our qualitative (>125 μm) and quantitative data (125–500 μm) allowed to distinguish three water−depth related assemblages in both Kon...
