Following David Ward's tutorial, i decided to make this in cycles. which lead few issues with the billboard particle system not working it seems. so had to make workaround for it, plane with texture, damp track constraint to track camera. then just use the plane for emitter and it worked.
the ocean is combine with the ocean modifier and Kent Trammels ocean shader which i tweaked a bit for this.
next stop volumetric clouds. :)
