Create dynamic compositions
One of the best ways to create depth in a seascape is to exploit foreground interest. Get in close to foreground elements with a wide-angle lens and they will loom large in the frame, with the rest of the scene stretching away behind them. This creates linear perspective, which replicates one of the ways the human eye perceives depth. On the coast there are plenty of options for interesting foregrounds: rocks, tidal pools, ripples in the sand and so on.
The key to strong composition when it comes to seascapes is simplicity. By keeping things simple and excluding any elements that are not fundamental to the composition and are potentially distracting, compositions are kept tight and it is easier to direct attention onto the key elements in the frame.
The logical extension of simplicity is minimalism, an approach which works extremely well with seascapes. Rather than linking a background subject with foreground interest, leave your subject surrounded by negative space. Long exposures complement this approach, as they remove surface texture from the sea, simplifying the scene further.
