| Purpose | |
| Abstract | SO-225 focused on stratigraphically controlled sampling of the igneous successions of the Manihiki Plateau. This has been accomplished by using the remotely operated vehicle ROV Kiel 6000 and chain bag dredges. The accuracy of the EM120 is usually critically dependent upon weather conditions and the use of a correct sound speed profile. During SO-225 sound profiles have been used recorded on SO-224 and SO-225 in the working area, ensuring the use of the correct sound velocity on this cruise |
