Ziel der Reise / Objectives of Cruise:

Cruise So 157 visited the pracific-antaretic ridge (PAR) adjecent to its intersection with the foundation seamount chain from 36.5 - 48.5 %. The cruise followed earlier visits to the foundation seamounts of the SF Sonne (1995) and the no Latacante (1997), which had discovered silca-rich lavas and indications of widespread hydrotermal activity along this part of the PAR crest and responds the present day position of the foundation plume as ~35 km west of the PAR crest near 37? 25' S. Motor objectivies of the So 157 cruise were to establish the nature of plumeridge interactions, to define the extent and genesis of the silica-rich lavas opting out along the ridge crest and to investigate the relationsship between the silico-rich and widespread activity. 66 stations were completed, comparising to dredge stations 10 TV-grab stations, and 6 OFOS (nidro-(slkd) stations.
