Purpose
Abstract SO191-3 set out to achieve further insight like the build up, life time, internal structure, long term behaviour, etc. at the seep sites at the Hikurangi Margin. A ROV was employed during the cruise to study methane seeps in fine scale resolution and to make in situ measurements. During SO191 a swath width of 120 or 100° was usually used for mapping. The system kept running during the entire time regardless if the ship steamed or was on station. New raw data files were started about every hour.
