The Navy-Princeton Gravity Expedition To The West Indies in 1932
S-48 was assigned at the request of the Hydrographer of the Navy by the Secretary of the Navy to assist with the second U.S. expedition to obtain gravity measurements at sea during using a gravimeter, or gravity meter, designed by Dr. Felix Vening Meinesz. The submarine was accompanied and assisted by the USS Chewink (AM-39) in a route from Guantanamo, Cuba to Key West, Florida and return to Guantanamo through the Bahamas and Turks and Caicos region from 5 February through 25 March 1932. The description of operations and results of the expedition were published by the U.S. Navy Hydrographic Office in The Navy-Princeton gravity expedition to the West Indies in 1932. The first gravity measurements at sea had been made in 1926 from a submarine of the Royal Navy. The first U.S. gravity measurements at sea had been made from the USS S-21 assisted by Eagle Boat 35 and Eagle Boat 58.

Famous quotes containing the words gravity, expedition, west and/or indies:
“Grown beyond nature now, soft food for worms,
They lift frail heads in gravity and good faith.”
—Derek Mahon (b. 1941)
“It is a sort of ranger service. Arnold’s expedition is a daily experience with these settlers. They can prove that they were out at almost any time; and I think that all the first generation of them deserve a pension more than any that went to the Mexican war.”
—Henry David Thoreau (1817–1862)
“There are acacias, a graceful species amusingly devitalized by sentimentality, this kind drooping its leaves with the grace of a young widow bowed in controllable grief, this one obscuring them with a smooth silver as of placid tears. They please, like the minor French novelists of the eighteenth century, by suggesting a universe in which nothing cuts deep.”
—Rebecca West (1892–1983)
“As the Spanish proverb says, “He who would bring home the wealth of the Indies, must carry the wealth of the Indies with him.” So it is in travelling; a man must carry knowledge with him, if he would bring home knowledge.”
—Samuel Johnson (1709–1784)
