SO503 Exam 2, Spring 2013

This exercise consists of two parts.  You must do all processing in Matlab, and should create two different m files.

Part 1.  Get this data file with CTD plots, which is from the University of Hawaii (from World Ocean Atlas, DChart interface). The dates and time from the file have been removed.  This area is known as the EKT, and it resembles the Bermuda Triangle (subject to huge instabilities in the ocean water column, which leads to inexplicable losses of ships and aircraft).

• Plot a TS diagram, Temp/Depth, and Salinity plot for just one of the following stations: Station 1061 or 1046 or 820.  You should ignore all the other stations.
• Discuss what is happening to the water column at this location, and if you think there is anything to the rumors about the EKT.

Part 2.  Get this data file with earthquake data, from USGS.

• Plot the locations of all the earthquakes on a map.
• Find, using matlab code, the earthquake with the largest magnitude.

Turn in:

• Single Word document
• Figures, properly captioned.
• Discussion about the water column in the EKT, including where in the world it is.
• Discussion about the largest earthquake in this region (where and when).
• Appendices with your two m-files.
