DORI Hydrophone

Abyssens

The DORI hydrophones are acoustic recorders powered by Lithium/Alkaline batteries, meant for short deployments (15 days), medium deployments (3 months) and long deployments (6 months). There is also a version without internal batteries (for vehicles or subsea stations).
It is possible to choose between Low Frequency (2 Hz – 30 kHz) and High Frequency (2 Hz – 250 kHz, which allows click detection from marine mammals including the harbor porpoise).

HydraSeis Multi-Channel Seismic Streamer

AAE Technologies - UK

The HydraSeis UHR system has been developed to acquire digital multi-channel Ultra- High Resolution (UHR) seismic data. The design methodology of the HydraSeis system compliments applied acoustics existing range of Ultra- High Resolution sound sources to provide a step change in performance for data quality.

The in- water internal 16kHz 24-Bit ADC modules provide digital low noise, wide bandwidth data acquisition. The 100MBps network data link to the system console provides continuous Ultra-High Resolution recording coupled with external navigation integration.

The flexible modular system allows for 2D and 3D UHR data acquisition at fast shot intervals for a wide range of marine geophysical survey applications.
