Oceanography Gift - 海洋学ギフト


Oceanography Gift(海洋学ギフト)

男: Happy birthday!
男: I got you these water molecules.

10 years pass

女: Aww, thank you!

Global surface ocean connectivity times are ≤10 years (Jönsson & Watson, 2016, DOI:10.1038/ncomms11239), so if you're willing to plan ahead, you can pour water into the ocean while wishing someone a happy birthday, and then in 10 years let them know they can pick up their gift at the nearest coastline.
 (世界の表層海洋の接続時間は≦10年である(Jönsson & Watson, 2016, DOI:10.1038/ncomms11239)ため、前もって計画する気があれば、誰かの誕生日を祝いながら海に水を注ぎ、10年後に最寄りの海岸線でプレゼントを受け取ることができると知らせて。)

Alt-text: Shipping times vary. Same-ocean delivery may only take a few years, but delivery from the Weddell Sea in Antarctica may take multiple decades, and molecules meant for inland seas like the Mediterranean may be returned as undeliverable by surface currents.
