BGK1000 pressing on with 200 N
Different clamping arms in action
BGK1000 Digital 3C Geophone System was presented at the exhibition booth of Geotomographie in Campus Griebnitzsee of the University of Potsdam 27th – 30th March 2017. The 77. annual meeting of Deutsche Geophysikalische Gesellschaft was organized by German Research Centre of Geosciences (GFZ).
Also on the booth: the new BHC1000 24-channel Digital Hydrophone String and the new SBS1000 Borehole Seismic Source.
Several promising discussions of seismic noise measurements with Multistation Borehole Geophons and aspects of high frequency seismic vibro sources.
On a four days mission in March 2017 the High Performance 24 Bit Digital Hydrophone records sound in 100 m depth. The recordings created new insights for this century-old problem of the success of catching fish.
The Digital Hydrophone is completely EMI-immune to powerline (50 Hz) or radio transmitter (RF) noise on the ship. Due to the very low input noise and the very high dynamic range it produces professionell data files in Waveform Audio Format (.wav) format with 48 kSamples and 24 bit resolution.
Measurements on three fisherboats in Runavík and Klaksvík to show the fisherman what kind of noises are produced on their boat while fishing.
The mission received strong interest also from media and the Marine Research Institute. The next set of experiments is planned in August 2017.

Six valuable logging tools, built in the eighties, got an new life and are back in business.
Now working with GEOCOM digital communication protocol to run on Antares Aladin Logger.
The new vibro firmware for our digital borehole geophone BGK1000 performes correlation and stacking directly in the sonde, cutting vibro survey times down to a half or less.
The new vibro firmware highlights include:
- Downhole stacking and correlation in each unit
- Trace length of sixty-five seconds (@ 1000 Samples per second)
- Extra long sweeps of more than sixty seconds
- Sixteen stacks of sixty-five seconds
- Correlation of stacking results, stacking of correlation results
- Real time noise monitoring, quality control journal
The new vibroseis upgrade is now available as add-on to new and existing BGK1000 systems.
Visit us at the SEG Conference in Dallas starting 16th Oct to 21st Oct 2016. Our digital borehole geophone BGK1000 will be presented by Geotomographie GmbH at the GISCO booth #924. Its a good opportunity to meet our colleague Sonja Mackens and to discuss applications of borehole seismics. See you soon.
BGK1000 just back from a 20 days mission in Western Australia.
A lot of seismic measurements were conducted by DMT at the begin of 2016 in Zurich, Switzerland using their new BGK1000-H sondes.
BGK 1000 is presented over 4 days in the exhibition of the 76. Annual convention of Deutsche Geophysikalische Gesellschaft in Münster, Germany, 14 – 17.03.2016.
