Marine Debris Training Continued: Surf Zone Rescues, Net Monsters, and Flipping Boats

Safety is our top priority for field operations, so we spent a week carefully preparing for emergency situations that could occur during the marine debris mission. Coincidentally, the weather sent us a few tropical storms that provided surf and wind for training.

“MD 1, this is MD4. This is a drill. Swimmer is in surf zone and needs assistance. This is a drill.”

“MD 1 copies. Dropping rescue swimmer in surf.”

After a rescue swimmer dropped into the water, they brought the “unconscious” swimmer back to the boat through the surf zone while the boat maneuvered and “held station” in the area. That was one of many drills we performed during our training in Kāneʻohe Bay, O‘ahu. We also swam as a team through heavy surf—assisting “injured” divers, removing a "net monster" in surf zones, and crossing channels with surf into open ocean.

You may be wondering: “What is a net monster?” Our dive instructor, Ray Boland, appropriately named it. The Net Monster is a tangle of fishing nets that we use for marine debris training. Our first interaction with Net Monster was during diver training when we were blindfolded and entangled in Net Monster while underwater on SCUBA. We had to remain calm and carefully disentangle ourselves without cutting the net. Overall, Net Monster was an excellent training tool for staying safe while collecting derelict fishing gear on our mission (and, not to mention, fun!).

We also teamed up and raced to cut a hauser line (thick docking line) and tie it back together while freediving.

Flipping a small boat for training

While it may sound like a bad idea to flip a boat, we need to know how to right a boat in an emergency situation. After donning our life jackets and helmets, we set off in pairs to flip an inflatable boat over and then flip the boat back up again (or “right” the boat). After mastering this skill in calm water, we then practiced righting the inflatable boat in the surf zone. While we hope that we will never encounter any of these situations in the field, we feel extremely well prepared to safely handle them.

Between all of our safety drills, we also practiced towboarding. Towboarding is essentially being towed underwater behind a small boat. We towboard to look for marine debris that may be caught on the reef. Although our team favors towboarding, it’s actually pretty difficult to drive the boat with towboarders while manning the GPS. We need good GPS tracks and points for the data we collect, but also need to ensure that our divers are safe—all while maneuvering around the reef!

Luckily, we have an amazing, well-trained team, who all worked hard to prepare for our mission to Papahānaumokuākea Marine National Monument.
