South of the Equator and East of the Prime Meridian, could be the Indian ocean.
"degree's south and degree's east" are too vague and can cover several oceans depending on how far you define the question.
South Pacific Ocean
15 S 75 E is the Indian Ocean.
There can be no such body of water, because no place on Earth can have a latitude coordinate greater than 90 degrees. The north pole is at 90 degrees north latitude, and the south pole is at 90 degrees south latitude. Those points are the farthest north and south you can go, respectively.
Those co-ordinates would place you in the Atlantic ocean - to the west of Africa.
That point is in the Gulf of Guinea, about 380 miles south of Accra, Ghana.
The South Pacific Ocean.
That is the Pacific Ocean.
Lake Superior
No single point on Earth has both a north and a south latitude. The Atlantic andPacific Oceans are both big enough to include points at both of those latitudes.
