Anyone know this book? SciFi, marine biologist who gets seasick

[Kris]

I was hoping someone new what book this is, I started reading it a couple years ago and wanted to get a hold of it again, but forget what is was called. All I remember about it is that it started out with a Marine Biologist, or someone who worked at sea, on a boat and her being seasick. I also remember that the cover of the book had a women swimming underwater, in a shirt and pants (not swimwear) and flippers.

Any help would be great, thanks

There was a marine biologist who got seasick at the start of Michael Chrithon's "Sphere", but he was male, IIRC. Not sure about the cover, since I've only read in a translation.
