Many tripods do adjust right down to ground level. The center post rises up and out of the way so that the legs can extend out to flat. It might mean lying down to look through the view-finder! Note, if you had had the camera on a tripod and a bit higher you could have included more of the ocean, for a nice middle ground to your composition. Wonderful image here!! Great color and shine of light over the rocks.

You might look into a "CamRanger" It will let you connect with an ipad (mini ipad!) letting you see what is in your lens and allows you to hit the shutter right from the computer.
I have an Olympus with a swivel LCD. Nikon and others have them, too.

One thought about your composition: Be aware of foreground or near foreground objects and their relationship to the horizon line. Note the largest rock, just left of center. The line of the horizon runs through it. If your camera was just a bit higher, the rock would be below the horizon line. I really do not know which is the better view, but it would just give you another option to look at later, two of the same view with the rock in two different placements.
This happened to me recently. A foreground bush looked better in the composition when I stood up to take the shot, putting the bush below the horizon. When I took the image, I really thought the lower look would be better. Luckily, I had tried both compositions.
