Benthic foraminifera as tracers of brine production in the Storfjorden “sea ice factory”

Eleonora Fossile et al.

Data sets

STEP2016 living foraminifera in surface sediments of a N-S transect in the Storfjorden Eleonora Fossile, Maria Pia Nardelli, and Meryem Mojtahid

Short summary
This study focuses on benthic foraminiferal distribution in an Arctic fjord characterised by continuous sea ice production during winter and the consequent cascading of salty and corrosive waters (brine) to the seabed. The inner fjord is dominated by calcareous species (C). In the central deep basins, where brines are persistent, calcareous foraminifera are dissolved and agglutinated (A) dominate. The high A/C ratio is suggested as a proxy for brine persistence and sea ice production.
