Uneven Test Border Extrusion

Hey all! I'm a brand new 3D printer who's enthusiasm far outweighs their knowledge base. I'm having issues getting an even test border printed. I ran the advanced calibration and played around with the calibration settings but I'm not seeing improvement. I wandered google for a bit and couldn't find any descriptions of issues quite like mine, but I did find this forum, so I thought I'd ask! What could be causing the globbing/unevenness on the test print, and how do I fix it? Pic in link, as the attachment set up on this forum is kinda shitty.

Thanks tons!

nozzle could be too close to the bed. Extruder temp could well be too low.
Extruder could be slipping.
It's pretty horrible - but could be a bunch of things causing it.
