EQF, I got really busy so have not spent adequate time with the information you posted on the previous thread, even though I requested you post it. When I get a chance, I'll go through this and then, if the question is not answered already, probably ask how you generate a global map of EM signals and what electromagnetic signals you are talking about. For example, if I remember my Intro Physics, light is EM, as are X-rays, radio waves....

Have to provide data, along with C.N., to the IODP (International Ocean Drilling Program) data base by Dec. 1. I think that is soon. This is for an area right offshore from UCSB campus. More on separate post later?
