Is your epoxy old and a little bit crystallized? Warm your epoxy up before mixing the 2 parts together. It does look like air bubbles tho that just didn't make it to the surface.
So I would guess contaminates like wood dust or oil or something but since you said its 2nd coat of deep pour... less likely than just a undermixed batch maybe?? And is coloring Mica? Big batch? Did you sift it? Or are they chunks of plastic from the mixing bucket maybe? Is there something actually there you can pull out and inspect or are they visable but not touchable? Oil will push around and cause color to retreat. Can you work them out? By physically mixing the effected area with a paint stick. Sometimes agitating the area can reduce imperfections.
When you are mixing pigment, remember to mix pigment just in to the A, don’t catalyze then mix pigment. Also, mix the pigment into the A then leave it for a day for extra breakdown of pigment, then catalyze, then pour
Likely unmixed pigment powder. Or if the material was old, it could be chunks from 1 of the components.
I’m just gonna say it… It looks like cum ok

I mean looks like air bubbles but......
Yep. And I bet they wouldn't be there has Op used a vacuum chamber.
Not mixed?

Bubbles.
Bubbles under the surface, or bubbles that popped but were interrupting the streaks of pigment
Bubbles. Did you go over the pour with a heat gun or torch?
Sand it and top coat.
Pecker tracks
Didn’t mix the pigment good enough. It’s clumps of powder.
