Abstract:
The gravimetric data was acquired with a sea gravimeter KSS32-M system, which was installed on RV Sonne near its centre of gravity during the SO267 cruise. The instrumental drift of the data was approximated by repeated gravity observations in the harbour of Suva both at the beginning and at the end of the expedition. In order to tie the measurements to the International Gravity Standardization Net IGSN71, gravimetric measurements with a LaCoste&Romberg gravity metre, model G, no. 480 (LCR G480) were executed both at the pier next to RV Sonne and at the next absolute gravity reference station at the Mineral Resources Department in Suva, Fiji. Additional processing of the data comprised the correction of the Eötvös effect using navigation data and the subtraction of the normal gravity. Data was acquired along a E-W trending profile in the northern Lau Basin at ~ 16°S between the 13.01.2019 and the 14.01.2019.
