"It's like winning the lottery twice - this is a very popular fishing ground, with half the North Sea fleet fishing here. As we hauled in the nets I spotted the bottle neck sticking out and I quickly grabbed it before it fell back in the sea."
Drift bottle 646B, as it is known, was released on June 10, 1914 by Captain CH Brown of the Glasgow School of Navigation, as part of a batch of 1,890 scientific research bottles designed to sink towards the seabed.
By tracking the location of returned bottles it was possible for the under-currents of the seas around Scotland to be mapped out for the first time.
The water-tight glass bottles contained a postcard asking the finder to record the date and location of the discovery and return it to the director of the Fishery Board for Scotland, for a reward of six old pence. Of the batch released in 1914, 315 bottles have been found.
The original log of Captain Brown, now held by Marine Scotland Science in Aberdeen, is updated each time a discovery is made. The previous record was held by a bottle which spent more than 92 years at sea.
