Cruise Report


Instrumentation:

  •     Sodera micro GI (Generator-Injector) Gun 2 x 0.1 L
  •     DuraSpark 400 (Fraunhofer IWES)
  •     Teledyne Streamer 220 m, 96 channels, single hydrophone groups


Funding for this cruise and related science is received through SEBAMO, our joint research project with BSH, to gain a better understanding of geologic conditions in the German North Sea, with a focus on wind farm areas. 

The third cruise in the sequence of BSH-MTU cooperation was expedition Atair009, where an analogous multichannel surface streamer, a micro GI air pulser, and a Dura sparker were utilized.

The main targets of the cruise were to collect multi-frequency seismo-acoustic data in the windfarm areas N-9 and -10. Adverse weather conditions affected data quality on various Sparker profiles, nonetheless, successful . 

 Data yield: 365 nm /  >37 profiles of seismo-acoustic data.
