Sediment Trap Cruise. Updates from the JellyFarm Work Package 1.

On 19th August the JellyFarm team Dr Andrew Sweetman (Heriot Watt University, Scotland), Dr Catherine Lalande (Laval University,  Quebec City), Dr Kathy Dunlop, Dr Wenting Chan (NIVA, Norway) and RV Solvik skipper Leon Pedersen set out to continue the work on JellyFarm Work Package 1.

Successful sediment trap retrievals were made in Lurefjorden and Masfjorden where the traps have been collecting falling detrital samples since Aug 2015.  Traps were redeployed in Hardangerfjorden where they will collect data for a further year to quantify fluxes of jellyfish POC.

Scavenger Traps

Scavenger traps (baited with dead Periphylla) were deployed at the same position as the camera lander after lander retrieval.  This was to allow us to collect specimens of the same species of scavengers observed in the camera lander images.
