Today the teams were back diving. Energy was high after yesterday's dive stand-down so the divers were raring to go.

After another incredible breakfast, three launch boats deployed to start the day carrying; the predator/prey team, the invertebrate team, and the receiver/video/lionfish team.

All teams had a successful day! Highlights include:

  • 10 divers, over 30 dives at 12 sites in Gray's Reef National Marine Sanctuary.

  • Creature highlights include a frogfish, several loggerhead sea turtles, a searobin "walking" on the sea floor, and an unidentified shark on the surface.

  • Extraordinary predation events from the predator/prey team.

  • Several dozen invertebrates were documented, and some were sampled to be further analyzed.

  • The receiver team successfully swapped out the batteries of three acoustic receivers.

  • Two invasive lionfish were removed by the lionfish team and invertebrate team.

  • Significant fish populations included scamp grouper, gag grouper, black sea bass, amberjack and spadefish.

Special thanks to the hard work of the tank refilling crew for keeping divers supplied with air!

Tomorrow the fun continues so check back for more interesting updates.
