The iceberg melted away long ago. Icebergs break apart from Greenland and Iceland when spring comes, and they drift south. So Titanic's iceberg would have melted as it drifted south into the equator area because of the warm temperatures.

Has nothing to do with global warming caused by humans, especially back then! Although the winter of 1912 was unusually warm they said. Thats why they had so much ice in the shipping lanes.
