in Davy Jones' locker

The court heard that Ms Watt had lost her phone in "Davy Jones' locker", aka the North Sea, after it was hit by a wave before Mrs Rooney's team could see WhatsApp messages between her and a journalist that could have potentially helped her case.

The theatrical Mr Sherborne noted it was "a shame" that the phone was "lying at the bottom of the sea in Davy Jones' locker".

Those cannons can tear holes in the hulls of other ships, forcing their crew to repair the damage, or face a death in Davy Jones' Locker.

To this the sea lord replied, "Every ship, sir, that is not in Davy Jones' locker, has the sea well under her, and, therefore, it may be asserted that she has complete control of the sea."

The azoic hypothesis, posited by Forbes in the 1800s that life couldn’t exist much deeper than 500 meters, was laid in Davy Jones’ locker through the improvement of dredging, depth measurement and water collection tools and the massive undertaking of the HMS Challenger expedition.
