Oceanography studies setup

... discharge technology and unique tip material. They do not require frequent maintanence even while working on large energies. To increase weather operational window and low energy content sparkers can be towed up to 5 m depth. Additionaly, multi-level sparkers working with MultiJack energy sources support cutting-edge shooting technology – pre-defined delay is used to shoot at each sparker level for each shot. This results in constructive interference of wavefields, generated by each level, resulting in increasing low frequency energy,...
