Sonne-Expedition SO254

Research Aim

Our research aim during RV Sonne cruise SO254 was the examination of sponge communities in the southwestern Pacific – from the sunlit surface waters down to the deep sea (~ 5 km water depth).

Besides taxonomy, physiology and chemistry of sponges, especially their associated microbes were in the focus of our research.  A prerequisite for those studies was the ROV Kiel 6000, which not only delivered our samples, but also valuable meta data that in turn allow an analysis of the respective deep-sea sponge habitat. The data of this cruise will represent an important piece in the puzzle for our biogeographical comparison of deep-sea sponge microbiomes in different ocean regions worldwide.
