The word "How?" springs to mind at this point.

Anchor cam

A social website gets shipowners to attach cam and LEDs to anchor

and share the images. All of sudden, sub marine research will receive so much more information. To be incorporated in Google Earth of course.

Edit due to linked video: with a small float keeping it above the chain or anchor where it is attached.

gopro on anchor - still with boats only but proof of concept https://www.youtube...watch?v=PUN4pWXYEzE

this idea reminded me of this great oil rig monster video https://www.youtube...watch?v=IJwGpZ38JHE

Melz ITM2M display tube https://www.industr...leview.php?item=949
Mentioned in my anno. 4-pixel module; would be tiled to make large Jumbotron-style displays [notexactly, Aug 10 2019]

       It would have to be some distance up the anchor cable to be useful, and even then the view would often be limited by light and silt/mud in suspension.   

       It would also mean the unit would have to be rugged enough for routine use in a marine environment, which is incredibly harsh - that would make the casing expensive, enen though the camera only cost $10.

       //and even then the view would often be limited by light and silt/mud in suspension// Yes, but stuff in suspension would only be a problem if the sea floor had recently been disturbed by... ah.

       Suspenseful movies can be popular.

       Limpet Cam: like an inverted kite, one end of a cable gets glued to the bottom of a container ship. The other end deploys a camera into the deepest depths for the duration of the cruise.

       Science has quite a range of sensors. Can SEDs be bought off the shelf?

       What's an SED?

       Sound Emitting Diode.

       Yes, you can buy sound-emitting diodes off the shelf, but they'll only emit sound once each.   

       Slightly more relevantly, it also stands for surface- conduction electron-emitter display, a flat-panel display technology that was given up on a decade ago. It's basically a scaled-down version of that Soviet Jumbotron tube [link] where each subpixel is its own CRT.
