Looking back at the lab experiment performed at IRIS (Stavanger) in September 2016, looking forward to work with this team on the next experiment in September 2017

WP2: Quantifying interactions between  aquaculture and jelly-falls on organic matter cycling in fjord sediments. 

Sediments collected in Hardanger fjord at two different depths, in the vicinity and at a distance from a fish farm were collected and incubated in the lab at IRIS.

Team work at its best!
