Last year around this time, we posted about Harold Hackett of Prince Edward Island, who since 1996 has cast 4,800 bottles containing messages into the sea and has received 3,100 responses. Harold may hold the record for the most bottle borne responses, but recently we learned of a Scottish fisherman who found the world’s oldest message in a bottle.  The bottle was cast into the sea 98 years old by Captain C. Hunter Brown, a scientist at the Glasgow School of Navigation, who was studying the currents in the North Sea. It was one of 1,890 bottles released on June 10, 1914, and the 315th to be entered into Captain Brown’s log, which is still kept and updated by Marine Scotland Science in Aberdeen.

Found: World’s Oldest Message in a Bottle, Part of 1914 Citizen-Science Experiment

I’d say this qualifies as a nearly century-old citizen science experiment, though that’s not a term scientists would have been familiar with then. Just take a look at the card contained in the bottle (which could be sent back to Hunter without postage). These drift bottles were data traps, intended to capture information with the help of regular people 

“Drift bottles gave oceanographers at the start of the last century important information that allowed them to create pictures of the patterns of water circulation in the seas around Scotland,” explained Bill Turrell, Head of Marine Ecosystems with Marine Scotland Science explained in the official press release on the event. “These images were used to underpin further research — such as determining the drift of herring larvae from spawning grounds, which helped scientists understand the life cycle of this key species.”
