#MarineScience - A team of young scientists have lost a special weather balloon probe somewhere in Dundalk Bay - and they've turned to the internet for help.

CoderDojo mentor Daniel O'Reilly, who has been working with the teens on their project for a national science competition, has appealed on Twitter for assistance, posting an image of the missing item and its last known location.

The silver duct-taped box is marked as 'Infinity-1' and was launched from Armagh on a weather balloon last Thursday 22 August.

The probe parachuted from 30km into Dundalk Bay and has not been seen since. It's last known whereabouts were at co-ordinates 53.09795, -6.29013.

If anyone finds the box, either in full in part, on the shoreline or in the bay, they are urged to contact O'Reilly at +44 (0) 770 890 5697 or 087 689 0785, or email [email protected]
