1) captain nemo must take his submarine from offshore manila to offshore seattle while staying submerged at 1000 m. he asks you, his navigation team, what maps, charts, or data set he should use to avoid running aground on a seamount. he points out he must make the journey without sonar, and that the on-board inertial navigation system has an accuracy of 1 km in the horizontal and 1 m in the vertical.

2) professor numero uno has a contract to develop a global, numerical, model of the ocean's circulation. the model requires oceanic depths every 0.25 degrees of latitude and longitude. what data set should he use and why? contrast and compare the recommended data set with other possible data sets. s)

what information do they obtain from the maps or data sets of ocean depth?

* which maps or data sets did you consider?

* which maps or data sets can provide the information needed by captain nemo and professor uno?

* can you trust the map or data sets? that is, can you recommend a particular map or data set with high degree of confidence?
