A key ambition of ATLAS Work Package 2 is to link the metabolic activity and biomass of deep-water sponges and cold-water corals (CWCs) to the supply of organic matter sources from the water column using mathematical modelling. This requires the development of physiological models of sponges and CWCs as a function of food availability. In the last decade, the body of literature on sponge and coral physiology has grown substantially, but unfortunately these literature reports have not be collected into a coherent database (e.g. using standardised units). Therefore, this deliverable has the aim to assemble and review the existing literature on physiology of CWCs and sponges. This deliverable will support the physiological experimental and modelling efforts planned within ATLAS.
