Sorry for your loss, been there, know how it feels to see your white hawk dawn. Hope you'll recover your footage, I didn't manage to do that, but my circumstances were a little bit different, as my bird felt from around 80-90 meters on solid concrete, so the card was totally distroyed. In your case, if you manage to find a boat fast, there are pretty good chances to save the shots.
Also, you can take your bird back home and let her enjoy her final rest on your desk

Good luck, hope you'll be back in the air soon !
