Abstract:

The raw 2D multichannel seismic reflection data in this project were acquired during expedition SO299/2 offshore Krakatau using a single GI Gun. The data were recorded with a 48-channel streamer. The Krakatau survey aimed to shed light on the erupted volumes of the disastrous 1883 eruption and decipher the processes leading to a damaging tsunami. The data comprise 381 line kilometers and are provided in raw format (SEG-D) and associated standardized metadata. Detailed information on the acquisition can be found in the SO299/2 cruise report (https://doi.org/10.48433/cr_so299_2). In addition, a technical report is provided with this data set.
