Scavenger Lander Cruise Preparation, Askøy, Norway.


Kathy Dunlop, Mark Berry and Leon Pedersen prepare the benthic chamber lander for deployments as a baited scavenger lander.  The scavenger lander will be tested next week in Lurefjorden and also used as part of a study to examine the affect of fjord water depth on scavenger jelly-fall feeding dynamics.

Boxcoring, Handangerfjorden.

 

This time the JellyFarm team were on there way to Hadangerfjorden collecting box cores at 380 m onboard the RV Solvik. 

Morning in Hadangerfjorden
Multicores were collected from the boxcores to set up an experiment in the laboratory at IRIS to examine the effect of jelly-fall decompostion on sediment ammonium and sulphate levels.  This ties into Workpackage 5 to study scavenging processes at jelly-falls.  This experiment will enable us to determin if toxic levels of ammounium and sulphates produced by jelly-fall decomposition may deter scavengers from removing jelly-falls.


This trip to Hadangerfjorden allowed us to try out some of the improvements to the design that Captain Leon had made to the boxcore.
