Using ship soundings to correct new and recently declassified satellite data, a team of geophysicists has produced the most detailed global map of the ocean floor so far: a 68-million-pixel panorama described on page 1956 of this issue. Some researchers are hailing the new database as our best view yet of this remote landscape, offering about twice the resolution of the best previous global map. Others fault it for failing to meet a cartographer's standard of literal accuracy.
