Integrated Ocean Observing System
Seven Societal Goals
•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
HIOOS Core Technology: Acoustic Monitoring
Hawaiian Archipelago Acoustic Array
Reef Fish Movements in Marine Protected Areas
Carl Meyer – Hawaii Institute of Marine Biology
Questions:
(1) Are reef fishes long-term MPA residents?
(2) Frequency of MPA boundary crossing?
(3) Habitat breaks = natural barriers?
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 Ecotourism
Carl Meyer & Kim Holland – Hawaii Institute of Marine Biology
Questions:
(1) Do sharks follow boats back to shore?
(2) Do sharks come into areas used for recreation?
Methods: Acoustic Monitoring
(1) Sharks implanted with transmitters
(2) Movements tracked with remote receivers

HIOOS Large Animal Tracking Goals?
Provide data for enhancing ecosystem stewardship by;
(1) Increasing monitoring coverage off Honolulu
(2) Integrating physical oceanography
(3) Modeling population dynamics of pelagic fishes
