Sediment echosounder raw data (Atlas Parasound P70 echosounder entire dataset) of RV METEOR during cruise M134/1
Sediment echosounder data using Atlas Parasound P70 echosounder was recorded during RV METEOR cruise M134/1. The cruise took place between 16.01.2017 and 18.02.2017 around South Georgia. The main objective of the cruise was to investigate emissions of free gas from cross‐shelf troughs of South Georg...
