2 weeks ago, I was reviewing the mission logs and checking them with satellite telemetry and discovered something very strange: energy signatures deep in the Atlantic Ocean, highly localized. I requisitioned additional computer time to print these logs for further analysis.

Performed Fourier analysis, as usual, with the HP calculator and a paper tape plot. Result: pattern resembles phase modulation, but bits jump. Not NAVSAT, not weather satellite.

Tested with a directional antenna – signal grows. Then it disappears. Like flipping a switch. Minutes later: back, exactly the same phase. Cannot be a natural phenomenon. Much too deep. Far below the pressure depth. But definitely man-made. I listened to it over and over, there is some pattern to it that I just cannot quite sense.

I took it to command. It might somehow be some kind of distress signal, perhaps some new classified submarine. They concluded they should forward it to technical analysis. Technical analysis wanted my raw tapes, so I gave them. 

The next day, some strange men visited me at my office. I did not recognize them, they had visitor badges. They and asked if I'd made any copies of the tapes. I said no. But of course I had. I always do.

Since then, I feel I'm being followed. My mail seems like it's being tampered with. But I continue to study the pattern.

I'll use Dutch in my private notes, in case they are read.
