HI,
Can someone please tell me how gravity waves are detected. Please note that I am talking about gravity waves "not" gravitational waves they are two different things. Any help is appreciated.
Thanks

in what medium?

Both atmosphere and the ocean but more on atmosphere. Thanks.

Please explain what you think the difference is.

Gravity waves has something to do with the sky (meteorology) and gravitational is something to do with astronomy.

Gravity waves is a fluid dynamics thing. I'll rummage through my applied maths notes if I have the time later.

Pretty sure it is, given he mentions atmosphere and ocean, which are the two canonical examples of gravity waves, and is talking about meteorology, not general relativity. Everyone seems to be confusing gravity waves for gravitational waves, and I think the op has made it abundantly clear that he is referring to the former.

If I wanted to measure and quantify them, I'd make a float like a fishing bob, on a shaft so it can only move vertically. Measure the position of the bob over time, and then use a Fourier transform on the list of numbers to identify the mixture of waves present.
