Show Freaks and Oddities In Science News A new great depth in the Caribbean sea feet has been discovered giving scientists a possible pos pos- sible new clue to origin of ot earthquakes such as recently rocked Santiago Cuba The new depth fathoms or nearly five miles greatest ever measured In that region has been located almost on the spot SCIENTISTS where the Santiago earthquake DISCOVER centered The navy announced GREAT DEPTH Thursday i its discovery by the IN CARIBBEAN submarine S 48 which Is cruising cruising cruis- cruis ing in ln the Caribbean with a crew f i it t i of scientists studying the causes of quake and other earth changes The new deep sounding was made mado in the Bartlett Bartlett Bart Bartlett lett deep huge ocean trough to the south of Cuba The greatest previous sounding there was fathoms or feet teet Some scientists believe the Bartlett deep is a surface Indication of a line of inward buckling of the earths earth's crust perhaps caused by shrinking of or the crush as ns the interior cools Earthquakes around the Caribbean originate along such a line of buckling according to the theory of Dr F. F A A. Dutch scientist who wh is cruising on board the S 5 He has found similar regions of buckling in the East In Indies Indies In- In dies and the Pacific The Bartlett deep forms a giant hole in the sea bottom as large in extent as the state of Pennsylvania Penn Penn- sylvania sylvani but shaped more like Long Lons Island The new depth was measured with a sonic depth finder a device that registers depth by the ime required for a sound to travel to the sea ca bottom and arid be reflected back to the ship from which it came Gravity is measured at sea while the submarine is submerged to provide a steady base for the delicate deli deli- cate cats swinging pendulum-swinging apparatus used |
