Ziel der Reise / Objectives of Cruise:

The aims of RV SONNE cruise SO263 in June 2018 were to explore and sample volcanoes at the northernmost end of the Tonga island arc and NE Lau Spreading Centre (NELSC). The sampling program included ROV dives, TV grab and wax corer deployments as well as vertical CTD deployments and CTD Tow-yos. In addition, bathymetric surveys were carried out in the working area. The main working areas were (1) Niua volcano, (2) the submarine island arc volcanoes south of Niua, (3) Niuatahi volcano, and (4) the southern portion of the NELSC. In each of these areas volcanic structures and hydrothermal vents were explored and sampled by ROV, TV grab and CTD. Wax coring along the NELSC recovered samples of volcanic glass. The cruise started in Suva on June 1st and we arrived in the working area on June 3rd. After 21 working days and a total of 131 deployments and bathymetric surveys the working program t
