Marine mammal Service (MMO) including passive acoustic monitoring (PAM) for a research cruise from November 22nd 2023 til January 4th 2024

BGR is carrying out a research cruise with a seismic reflection and refraction survey with the German RV SONNE in the central Indian Ocean close to the Rodrigues Triple Junction. Research cruise SO301 with the project acronym SCIROCCO is aiming to record a seismic image of the Central Indian Ridge. The survey starts on November 22nd 2023 in Port Louis, Mauritius, and will end on January 4th 2024 in Port Louis. During the survey, seismic reflection and refraction profiles will be acquired for a period of approximately four weeks using a 8 km long 2D-streamer and many ocean bottom seismometers. The seismic source array is a tuned G-gun array, consisting of 16 G-guns arranged in two strings (port side and starboard), each string consisting of 4 clusters with a pair of 2 G-guns. The total volume are 3100 cuinch (50 liters).
