Back when people where still trying to learn about the oceans and directions of currents, nice find:

"The message is dated 12 June 1886 and was jettisoned from the German sailing barque Paula as part of a long-term German oceanographic experiment to better understand global ocean currents and find faster, more efficient shipping routes."

Havent read the article. But i wanna say that i expect it to be shallow.

I saw this a few weeks ago. Message in a bottle as perhaps foreshadowing?
