Require high-quality stereo audio recordings of rain/rivers/ocean

I am looking for some audio recordings of the above categories. I'd need uninterrupted clips, preferably with no sound artefacts of other noises/sounds. Looking for about 2-3 hours worth of recording for each option.

I'd need the files in WAV and recorded in stereo. Preferably using a mic similar to a Zoom handheld recorder with a built in stereo microphone.
