My wife an I completed OW training about 6 weeks ago. The week after that we were on a cruise where we completed 4 dives in the western carribean, 2 shore dives and 2 boat dives (to about 65'). None of those dives produced any ill effects for my wife.

The past 2 weekends we did a shore off of Bradenton Beach on the west coast of Florida. Both dives were in less than 25' but were plagued with low viz - 5-10'. On the first dive we encountered a lot of jellyfish, but didn't see any on the second dive (although at 5' viz might have swam right past them).

On both of these dives, my wife experienced extreme nausea after about 20min on the bottom causing us to abort the dive at that point. It was so extreme on the 2nd dive that she vomited after returning to the surface. The effects cleared up after a couple of hours.

As a note, she is prone to motion sickness and was wearing a seasickness patch while on the dives for the cruise.

Would the low viz be a key factor in triggering a vertigo condition?

There was some surge on the 2nd dive, but not the first. And she reported feeling less nauseous when close to the bottom (where she could actually see the bottom).

The nausea got better after we surfaced, despite a minor chop that kept us bobbing - which I thought would make things worse.

Would like to figure this out so we can have more enjoyable dives, as she's actually enjoying this new hobby I dragged her in to.
 
You say the vis was low, I'm guessing there was a lot of visible particulate matter in the water. When I see particles swooping up and down in front of my mask it gives me vertigo. I have to focus on something that's not moving (my gauges for instance) to keep nausea at bay. Waves have the same effect on me; when I swim to the boat I always swim a foot or so underwater because the air/water interface moving in front of my mask makes me sick.

The bottom surge was probably it. Seaweed or even loose sand that is moving back and forth out of sync with your percieved motion will put your brain into "tilt mode" and there does your equilibrium. The same thing caused my wife to cut a dive short this summer.

When I feel it a bit I close my eyes as an immediate circuit breaker. Focusing on instruments that are movng with you or even swimming across the surge will help.

Ditto.

I'm pretty resistant on the surface of the water, but just the thought of sea fans, sea rods and seaweeds swaying profoundly in the surge makes me queasy.
