here there are some nice examples: http://www.g3eo.info/seismicreflection_examples.html

Here nice examples, take a look: https://g3eo.com/examples.html

I found three models here https://www.syqwestinc.com/products/sub ... -profilers: (1) Bathy-2010P, (2) Bathy-2010PC, (3) Bathy-2010, are these basically the same systems or do you notice any significant differences? Thanks for any pointers.

Hi,
Does anyone have a multibeam system for rental? If so please let me know my email is gery@g3eo.com, thanks.

Hi,
Does anyone have a chirp bathy for rental? If so please let me know my email is gery@g3eo.com, thanks.

Hi,

Is there someone selling a magnetometer system for shallow water surveys? please let me know, thank you.

Best,

Gery

try:

suoldtonew < data2013.su | suxwigb &
suoldtonew < data2013.su | suximage &

This worked perfect thanks Gery.

you're welcome EltonM!

Dear gurus, This is a question about practical rules of thumb to compensate seismic amplitudes of shallow-water (e.g., ultra-high resolution) seismic data for attenuation losses. In this kind of data, attenuation is expected to be high due to the high-frequency sources used. Therefore, to correct fo...

Just run
and check that path

I looked at it wrong, sini^2+cosi^2=1, thanks geophix and sorry for the noise guys, I think too much coffee

Hello, I have kind of a dumb question here, but I will ask it anyway. I read a simple formulation (equations 1, 2 and 3 using figure 1in attached paper) and got confused. If you took a quick look, 'p' and 'q' variables (equation 3) should be 1/sini.V and 1/cosi.V, respectively, based on equation 1. ...

thanks for sharing, but you used some SEGY as input in your posts (as well as geometry info), could you share those? I think that is useful so people can test what you did.

A man is going to an appointment and he notices that he is lost, so he stops in the middle of the street and asks someone there: - Excuse me!!, could you help me? I had an appointment at 2 o'clock with a friend and I am 30 minutes late and I have no idea where I am!! - Of course I can help you -answ...

Thanks guys for your answers and links, I appreciate that, cheers.

Thank you guys for the answers and links, so the prices range between USD 200m and 10m, as expected, the newer the more expensive. But I am actually thinking on the system itself, and if I buy a 3D full-equipped system (let's say 8 streamers) I could easily do 2D surveys, right?. Now, such systems a...

and how much would that be? any idea?

Hello, Imagine I win the lottery today (around USD 1M) and I want to buy offshore seismic systems (2D, 480 channels, 12.5 m spacing, 6 km; and 3D, 360 channels, 3 or 6 streamers). How much would I need to buy such things? I mean, the whole systems? both scenarios, new and 2nd hand, would be great to...

Thanks a lot GuyM, I appreciate your explanation. I have no further details to give you an answer to every question you asked, but it seems to me that it wouldn't be the worst-case scenario, so 2 months sound like a good time to me. Again, this is just a simple question, no real survey involved thou...

This is probably a bit "broad" because several related issues (such as funding, administrative stuff, etc, etc), but imagine everything is in order, so I was wondering if someone knows how long it would take to acquire marine 3D multichannel seismic data (3 surface-towed streamers, 3 km each) in wat...

Question: Why does a geophysicist like rational women?
Answer: Because they are anomalies.

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. really?? btw, you don't work for stratabox, do you? it would be good to have some of those gre...

Hello,

Would someone have a software to convert Phoenix I format (vendor called Phoenix Data Solutions, probably the proprietary format) to SEGY standard? afaik it derives from the SEGX exchange format that preceded SEGY.

Any hint on this will be appreciated,

Cheers,

Glad to hear that it helped you, enjoy playing with it and learning!

Thanks Gery, Now it works.but we also get: suoldtonew: converted 735 traces to XDR format. what is this? we need data in su format,that i have already. Why earlier it was not working? Can explain it? can you tell me step to correct the headers. you're welcome ranjeet, to your questions: 1. as far a...

I think it's not the correct definition, oceanography is one branch of the Earth sciences that studies the biological, geological, chemical and physical processes occurring in oceans and seas. So, oceanography is like geography, one branch of the Earth sciences.
