Purpose | |
Abstract | The expedition SO201-1B aimed of sampling volcanic rocks at seamounts, submarine ridges and fracture zones in the Northwest Pacific and the Bering Sea. Reconstructing the age, source and development of these structures will contribute to the main objective of KALMAR, to better understand the Geosystem Kurile-Kamtchatka-Aleuten-Arc. The accuracy of the depth data obtained from the EM120 is usually critically dependent upon weather conditions and the use of a correct sound speed profile. During SO201-1b sound profiles have been used recorded on SO201-1a in the working area, ensuring the use of the correct sound velocity on this cruise. |
