ADEON Marine Mammal Observation Logs

The Marine Mammal Observation (MMO) database it is a record of marine mammals and turtles sighted during daylight hours at each ADEON lander location (link to map). On-station effort commenced approximately 5 nautical miles prior to arrival at the lander location when the ship slowed its speed to below 8 knots. MMO effort concluded at approximately 5 nautical miles from the lander location before the ship increased speed above 8 knots. Opportunistic sightings from night time hours occurred when animals were visible around the lighted decks. These sightings are included in the MMO but are not included in the on-effort daily calculations.
