NATO Undersea Research Centre (NURC) in Italy conducted the CATHARSIS2 sea trial from October 5-20 in the waters near Elba Island, Italy to investigate underwater object detection technologies. On October 20, harbour security demonstration for local military and civilian authorities was conducted at La Spezia, Italy. For the first time, U.S. Navy’s Marine Mammal Fleet Systems participated in these exercises.
Some interesting features of U.S. Navy’s Marine Mammal Systems (MMS), NURC and CATHARSIS2 sea trial are:
- U.S. Navy Marine Mammal Fleet Systems
- Assigned to the Explosive Ordnance Disposal Group ONE (EODGRU ONE).
- Uses dolphins and sea lions to find and mark the location of underwater objects.
- Dolphins with their exceptional biological sonar can detect objects in the water column and on the sea floor.
- Sea lions have very sensitive underwater directional hearing and exceptional vision in low light conditions.
- MMS MK 4, MK 7 and MK 8 use dolphins.
- MMS MK 5 uses sea lions.
- MMS MK 6 uses both dolphins and sea lions.
- MMS can be deployed rapidly within 72 hours of notice through ship, aircraft, helicopter, and land vehicles anywhere in the world and they regularly participate in major Fleet exercises.



prevention of pollution of the marine environment. This is possible only when ships are safe at sea and, ships can be safe only by carrying out good maintenance onboard. To keep the ships safe and seaworthy, ClassNK has published in February 2009, “Good Maintenance Onboard Ships: Maintenance Checklist for the Master”.

An MIT/WHOI graduate student, Stephen Licht has built an Autonomous Underwater Vehicle (AUV) called Finnegan. Unlike conventional underwater vehicles that use propellers, Finnegan uses flapping foils to maneuver. The idea to develop this AUV with flapping foils has come from Myrtle, a 500-pound, at least 70 years old, green sea turtle at the
