STEP 1
Create a new Document, 200×200 pixels, RGB color, set background to any color.  (The size doesn’t really matter, I selected that size just for the sake of this tutorial.)
STEP 2
Do Filter->Noise->AddNoise.  Use Gaussian, Max Amount, non Monochomatic.
STEP 3



Do Image->Adjust->Hue/Saturation.
Make sure Colorize is selected.  Set Hue to -149, Saturation to 100, Lightness to 0.
You should get something similar to the image on the left.
STEP 4



Do Filter->Blur->GausianBlur.
Set the value to between 2.0 to 3.0.
STEP 5



Do Filter->Ripple.
Select Medium, and set the amount to Maximum.
You should get a nice water effect as shown on the left.Before you do the next step, name the current layer: “Flat Sea,” then make a copy of the layer so that you can experiment with additional effects later. 
STEP 6



Do Layer->Transform->Perspective.
Drag the bottom-left anchor to the left until the extended length is about twice of the image width.  (Or experiment with any setting you like.)  That will do it, and here’s what I ended up with: a nice calm sea water.   
In the following steps, I’m showing a slightly different effect that can be accomplished, you can either stop here or continue.
STEP 7 (OPTIONAL)



Activate the saved Layer named Flat Sea that you create in STEP 5.Do Filter->Emboss.
Select Max Height, Amount 160, set angle to 90 degree.
STEP 8 (OPTIONAL)



Do Image->Adjust->Hue/Saturation.
Make sure Colorize is selected.  For the image shown on the left, I selected Hue of -153, Saturation of 0, and Lightness of 0, but you can try different setting and find what you like.  For now, though, try to stick to Hue values between -110 to -170.
STEP 9 (OPTIONAL)



Adjust the perspective as you did in Step 6. Now we’re done, here’s the wild
