3. 1-yr battery life – scheduled turn on/off Time-series data 30 kHz analog bandwidth Shallow water version a b c d Deep water version Acoustic Release EAR in alum housing Syntatic foam float hydrophone BACKGROUND Ecological Acoustic Recorder (EAR) Developed jointly – HIMB & NOAA (CRED)

4. OBJECTIVE: HiOOS Environmental Acoustics 1.Install a real-time acoustic monitoring system at the Kilo Nalu Ocean Near Shore Reef Observatory 2.Collect and analyze acoustic signals from a near shore reef environment

5. The Wet End Underwater Connector Hydrophone Modify EAR Ethernet ready (Jim Jolly & Dave Harris) Aluminum housing

11. THE BIGGER PICTURE 1. One acoustic observatory is great! 2. Two acoustic observatory is even better – Station Aloha

12. DOLPHIN WHISTLES FROM STATION ALOHA 1 2 3 4 5 6 7 8 9 10 11 12 0 12 3 4 5 KHZ SEC HYDROPHONE AT 5 km depth  3 miles Dolphin whistles

13. THE BIGGER PICTURE 1. One acoustic observatory is great! 2. Two acoustic observatory is even better – Station Aloha 3. Many – multiple – EAR – simultaneous acoustic observatory is the best Have had a number of EARs on the Waianae coast to study spinner Dolphin utilization of the coast line 4.HIMB Teaming with NOAA – CRED NWHI Monument ONR 4 in NWHI & 4 more to be deployed this summer 3 in a array on a slokum glider – this summer feasibility test with OASIS PERHAPS WITH NOAA-PSD IN THE FUTURE 30 DEPLOYED WORLD-WIDE 13 for CRED

14. ONR Program – Fiscal Yr 2009 EARs simultaneously recording for dolphin & whale sounds

15. Kilo Nalu EAR FUTURE SPINNER DOLPHIN DISTRIBUTION PROJECT

16. CONCLUSIONS 1.Kilo-Nalu acoustics will be unique – like Station Aloha - provides real-time data 2.Good & important data can be obtained for scientific & management purposes 3.Still an emerging technology – hardware & data analysis 4. Future – web-based satellite links
