Jelly Farm Incubation Experiments

Jellyfish (Periphylla periphylla) weighed to be added to benthic cores

Microprofiling is conducted right before core processing begins

JellyFarm Field Work Kaldfjorden, Troms


Monday 4th to Thursday 7th of September the JellyFarm team were out in Kaldfjorden to collect box core sediment samples for benthic core incubation experiments.

Experiment chambers were carefully pushed into the sediment in box core and sent over to the lab for further incubation experiments.

Silvia and Anouk slicing sediment cores for further chemical, foraminifera, 13C and nematode analysis.


Despite some difficulties with coarse and rocky seabed several Gemini cores were also collected in Kaldfjorden.



Kaldfjorden Sediment Trap Deployment

Sediment traps were deployed in the Arctic fjord Kaldfjorden, Kvaløya, Tromsø on the 8th September 2017 by Andrew Sweetman (Heriot Watt University), Marta Cecchetto (Heriot Watt University), Hege Vågen (University of Oslo) and Carl Ballantine (Akvaplan Niva).  

Traps will remain in the fjord for 10 months were they will measure the flux of organic material to the seafloor close to a fish farm and in a control site in the center of the fjord.
