With the camera on a tripod, and the sun well below the horizon (just a faint glow left), it sure would. Part of the effect in this particular pic is due to the light source coming from over the cameraman's right shoulder. My guess is that there were some buildings or a pier up the beach a little way. Whoever took the pic walked away from the lights until s/he thought it was dark enough and started shooting. Or, that could be moonlight, but it looks too yellow. May well have counted on the light from behind the camera to help illuminate the beach a bit and give the scene some depth.
Try it some time with a bunch of different exposures, maybe 1/16 sec to 1 sec, maybe a bit more. Taking the bioluminescence out of the equation (unless one happens to be somewhere with a lot of bioluminescence), anyone could replicated the rest of the effect fairly easily. Nowadays, with modern ccd and cmos cameras, this sort of thing is a snap. Once upon a time, we had to shoot a roll or two of pics at various settings and wait until we had them developed to see if we had anything interesting.
Look at some of the other pics in that link. They are more obviously taken with long exposures.
Never forget them. Do something to prevent it from happening again.
