Advice for buying a sub-bottom profiler

Post by Vlad Lazar »

Hi guys!

The company I'm working for wants to buy a sub-bottom profiler and I was as asked to scan the internet. We would like to have a device that could be portable and be deployed by hand, as we are working mainly on small boats without cranes, in shallow waters. It would be very helpful if you could tell me facts regarding your personal working experience with those type of sub bottom profilers, after all the websites are made to show only their strengths.

Thanks a lot,
Vlad

I recommend Edgetech 3100, it is portable by hand (but it might need two people) and suitable for shallow water. I have used it in water as shallow as 6 feet and the data is still good. You can deploy it behind your boat with a rope without any problems. You may want the smaller antenna (SB424) instead of the bigger and heavier SB216.

I've seen a lot of success using the Stratabox from Syquest in everything from deep bays to 2' deep settling ponds. It produces decimeter resolution and you can mount it on smaller craft like inflatables.

Don't buy any Syquest products! I have very bad experiences on their products.

Thank you for your replies! The EdgeTech sub-bottom looks nice. We are not quite on a short budget, so we would rather prefer quality, the Stratabox sounds like a low cost solution and last year we have bought a StarFish side-scan sonar that was a low cost, but the data was not satisfying.

We have also thought about this systems:
Inomar SES-2000 compact SBP
IxBlue SSD Echoes 10000
Teledyne TTV 170

Does the EdgeTech comes with a software that can process data after the acquisition like the IxBlue? Do you have any idea on how expensive could be the whole solution if you must buy licence for a processing software?

Thanks!

The EdgeTech 3100 does not come with a processing software, but I am sure you can also use DELPH to process the data. About the price, maybe DELPH on this board can answer the question. :D I guess it's not cheap, but the software does look very nice.

I think that the Edgetech system has a facility for converting data to SEG - Y. SEG Y format files for sub-bottom data can be processed successfully using:

1) Hypack
2) Dr Geo
3) Chesapeake
4) CODA

Applied acoustics and Geo-Acoustics also make sub-bottom profiler systems.....

Yes, for the Edgetech system, you can save the data in SEG-Y format. There shouldn't be much problem for data processing. However, I doubt whether you should choose Hypack for the data processing. Hypack is good for side scan sonar data processing, but the functions for sub bottom data processing still need to be improved.

I've looked for Geo Acoustics and Applied acoustics... do you think you can operate their sub-bottom profiles only by hand, with no use of a crane? The Geo-acoustics SB looks quite big and the Applied Acoustic system integrates streamer cables and the whole systems looks fairly large (our boats are not bigger than 9 meters, for a larger ship we rented a fishing boat but we cannot rely on that). The CODA software appears to be promising, thank you!

Do you think the Kingdom software is good for processing? Gmowoe, what software have you used for that? (thanks for the link to the topic).

Thank you guys,
Vlad

We have not used the instrument in a while but it was working well when we shelved it. We have shifted our focus to high resolution, multi-channel towed streamer operations preferring to apply our techniques to imaging deeper strata.

Would you mind to tell me what multi-channel towed streamer you switched to? I am using EdgeTech 3100 in a regular basis for my sub bottom profiling and wondering whether there are other good options.

really?? btw, you don't work for stratabox, do you? it would be good to have some of those great images having decimeter resolution (I imagine that decimeter structures have been seismically resolved with such devices).

I guess it's around $30,000 to $40,000?
