Title

Anak Krakatau hydroacoustic data - Seismic and multibeam bathymetry (NERC Grant NE/T002034/1)

Abstract

Single Channel seismic data, Sound source - 8kJ Sparker; Recorder - EG&G 8 element marine hydrophone (streamer), stored in jpeg and SEGY files. Multibeam bathymetric data recorded by Teledyne Reson T20-P Multibeam echosounder (MBES) 200 - 400kHz. Positioning system using Differential Global Positioning System (DGPS) Trimble SPS 461 with OmniSTAR signal correction and computer-based navigation/data acquisition system with Qinsy Acquisition software. Hunt, J.E., Tappin, D.R., Watt, S.F.L., Susilohadi, S., Novellino, A., Ebmeier, S.K., Cassidy, M., Engwell, S.L., Grilli, S.T., Hanif, M., Priyanto, W.S., Clare, M.A., Abdurrachman, M., Udrekh, U., 2021. Submarine landslide megablocks show half of Anak Krakatau island failed on December 22nd, 2018. Nature Communications 12, 2827.

Lineage

The 2018 Anak Krakatau collapse was mapped with satellite imagery. The offshore region was mapped with pre-existing hydroacoustic data and from these interpretations a grid planned to map the eater depths and the subseabed architecture of the collapse
