It may very well be, as W8JI has suggested, that many of these are
harmonics of VLF beacons. I would guess this to be most likely for those
signals that transmit essentially continuously. Driftnet buoys (not
beacons) are battery powered and are usually transponders and are
presumably turned on only to ascertain their position.
