Science Buddies: "Ask an Expert"

Hi

We are doing the project that measures the diameter of Earth's core using seismic wave measurements recorded by USC's GEE database.However, the blue triangles that indicate available info aren't showing up. Does anyone have an idea for a solution?

I am seeing the same thing when I tried. I'm not sure why that is happening. I even let it set for a few minutes to ensure it just needed longer time to load. I suggest you contact the makers of the software (they provide an email address in the help section), explain your problem, and ask for a resolution. The databases could be down or there could be a glitch in the software.

Good luck!
