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. |

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? |
|
| |
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. |

I thought an SED was Smoke Emitting Diode - as discovered recently in one of the systems we were testing. |
