Sediment coring in Lurefjorden

Sediment coring took place in Lurefjorden to determine how a jelly-dominated ecosystem can influence the foraminifera composition within the fjord. Comparisons will be drawn between Lurefjorden, where the jellies are, and Masfjorden, a fjord with no Periphylla. Cores were taken today from 3 different sites in Lurefjorden, at depths of 444 m, 350 m and 200 m.

Selecting 1 cm sections of the core, to be analysed post-cruise for composition changes with depth. From this, it can be possible to determine the sediment accumulation rate of the fjord, which has not previously been explored. Pictured: Magnhild Torper, Silvia Hess and Elisabeth Alve.
