The fish observed in each picture were then counted along with rays, brittlestars,
starfish and other fauna. The geo-referenced data of the first dive (PS64/347-1) was
mapped (Fig. B5.5-6). The highest Lycodes densities were recorded at the centre of
the volcano and in an area south of the centre. Further conclusions can be drawn by
overlaying fish abundance with environmental data (e.g. sedimentology, habitat, and
bathymetry). The area of high Lycodes density in the centre, for example, appeared to
coincide with a site where the highest temperatures were measured by Kaul and
Heesemann (B. 3.1.1) during this cruise.
