Large Animal Tracking(Ecosystem Stewardship Component of HIOOS)
•Improve the safety and efficiency of marine operations
•More effectively mitigate the effects of natural hazards
•Improve predictions of climate change and its effects on coastal populations
•Improve national security
•Reduce public health risks
•More effectively protect and restore healthy coastal marine ecosystems
•Enable the sustained use of marine resources
Integrated Ocean Observing System Seven Societal Goals
HIOOS Core Technology: Acoustic Monitoring
Hawaiian Archipelago Acoustic Array
(1) Are reef fishes long-term MPA residents?(2) Frequency of MPA boundary crossing?(3) Habitat breaks = natural barriers?
Questions:
Kealakekua BayMPA
Reef Fish Movements in Marine Protected AreasCarl Meyer – Hawaii Institute of Marine Biology
Methods: Acoustic Monitoring(1) Reef fishes implanted with transmitters(2) Movements tracked with remote receivers
Preliminary Results:(1) Most reef fishes are resident at Kealakekua MPA(2) Scale of movements varies among species(3) Some species cross MPA boundary daily(4) Reef fishes rarely cross major habitat breaks
Public Safety Implications of Shark EcotourismCarl Meyer & Kim Holland – Hawaii Institute of Marine Biology
(1) Do sharks follow boats back to shore?(2) Do sharks come into areas used for recreation?
Questions:
Methods: Acoustic Monitoring(1) Sharks implanted with transmitters(2) Movements tracked with remote receivers

3,800 km
(1) Increasing monitoring coverage off Honolulu
(2) Integrating physical oceanography
(3) Modeling population dynamics of pelagic fishes
