Isn’t the Challenger Deep, deepest part of the Marianas Trench, named after the British ship Challenger? I remember watching a show on History Channel, “How the Earth was Made” about the trench and the work the Brits did on the late 1800’s measuring the ocean, discovering the depth of the trench with a rope and an iron weight.

Yes, that's the one. This was one of the many projects devised by the Admiralty to keep the Royal Navy occupied, and its brightest minds engaged, during the hundred years after the end of the Napoleonic Wars in which it had undisputed command of the high seas.
