Figure 4.3.1. Stones at the sea bottom covered by encrusting coralline red algae and looselying, branched forms, rhodoliths, intermixed. A number of sea urchin, Strongylocentrotus droebachiensis, are apparent. (Photo: Martin E. Blicher). 78 The sea urchin, Strongylocentrotus droebachiensis, occurs frequently in the coralline red algal dominated area (Fig. 4.3.1) (ME Blicher, pers. comm.) and is considered as very dominant in Kobberfjord in the assessment area (Blicher et al. 2009). In general, the existing knowledge of macroalgal diversity is very limited, and macroalgal species composition, biomass, production and spatial variation are largely unknown in the assessment area. Therefore, important or critical shoreline intervals cannot be identified based on the available information. In addition, at present only limited research addresses the littoral zone and no research has been conducted on subtidal macroalgal community interactions in the assessment area. Hence, the knowledge of biodiversity/abundance of macroalgal associated fauna or mapping of macroalgal /faunal interactions including grazing by, e.g., sea urchins, is lacking. Therefore, it is suggested that investigations are preformed to provide data and further information on: • Diversity and spatial variation of the marine flora and associated fauna in the littoral and sublittoral zones • Macroalgal and associated faunal biomass as well as species specific coverage or number • Benthic primary production Studies of this nature would provide robust data for mapping and modelling the littoral and sublittoral ecology of the Davis Strait coast of Greenland. This would optimise the advisory and assessment capability for shoreline protection and clean-up in relation to oil activities, as well as evaluation of subsequent rehabilitation of an oil impacted coast.
