Preface The expedition ARK XIX/3 with the German icebreaking RV ...

Considering the observed 5000 m² video and still photo material of Milkov et al. which
covered 0.5 % of the edifice of the mud volcano [3], it should be emphasised that the
new data set is 20 times more extensive and covers more than 10% of the sea-floor
area. Fig. B5.4-4 represents the tracks of the mosaics and shows the full extend of the
video mosaicking surveys.

This very successful data collection will deliver an insight into the habitats of the
Håkon Mosby Mud Volcano better than before. The mosaics will be analysed for
habitat types according to Milkov et al., 1999: smooth mud, mud with holes, mud with
ripples, mud with relief, seafloor with bacterial mats (Beggiatoa), seafloor with
tubeworms (Pogonophora) with a comparable method like in Bergmann (this issue).
