Hydrographic Surveys Limited have recently lost an instrument in Dublin Bay.
It was on the bottom and made fast to a red marker buoy. Divers have checked the bottom and it is no longer there. (It was most likely either trawled or caught in a vessels prop and dragged)
An image of the instrument is attached above.
A reward is offered for its recovery.
If anyone has seen such an instrument (or even the red marker), please contact info@hydrosurvey.com
