I've observed a signal I'm unfamiliar with, and am wondering what it might be:

The period of time it lasted is 5 seconds, and it occurs irregularly. You might be able to see it too via WebSDR.

How would I discover what type of signal this is, generally, and does anyone know off the top of their head what it is?

One possibility is Digital Radio Mondale (DRM), but given that it's only five seconds long each time - exactly - I'm not sure. It does consume the same 10kHz bandwidth, and has some pattern similarities.

Here's one resource for visual signal identification: http://www.rtl-sdr.com/signal-identification-guide/

Digital modes are given a pretty thorough treatment with included waterfall signatures here:
