NOAA Photo Library Image - map00027

This map, by Augustus Petermann, was the first bathymetric map of the Pacific Ocean. Data was acquired by the CHALLENGER, the USS TUSCARORA, and the German research ship GAZELLE. Note the much denser sounding information on the TUSCARORA as the result of first use of piano-wire sounding. Note the Tuscarora Deep, first discovery of a trench, today called the Japan-Kuril Trench.
