THE KOHOLA PROJECT
Collaborator: Neil Frazer (SOEST)
Theoretical development and implementation of passive acoustic methods for tracking underwater sound sources. Applications to humpback, sperm, and beaked whales using bottom-mounted Navy ranges (Atlantic Undersea Test and Evaluation Center, Bahamas, and Pacific Missile Range Facility, Kaua'i).

HARBOR ACOUSTIC MONITORING SYSTEM (HAMS)
Collaborators: John Allen (Department of Mechanical Engineering, UH)
Part of the CIMES (Center for Island, Maritime, & Extreme Environment Security)
Development and testing of passive acoustic methods to improve our awareness of potential threats in coastal and harbor environments. Particular advances are sought in separating, identifying, and tracking multiple signals in noisy shallow water environments. The first test site will be at UH's Kilo Nalu Nearshore Observatory on Oahu's south shore.

CROSS SEAMOUNT
Collaborators: Jeff Polovina, Dave Johnston (NOAA, NMFS, Hawai'i)
Detection, classification, and quantification of boat traffic, meteorological phenomena, and biological activity at Cross Seamount using passive acoustics - examining one year of HARP (High-Frequency Autonomous Recording Package) data.

ALOHA STATION HYDROPHONE
Collaborator: Fred Duennebier (SOEST)
Measuring wind and rain characteristics using ALOHA hydrophone data.

Sound pressure levels (not referenced) as a function of frequency for different wind speed

SEDIMENT ACOUSTICS
Collaborators: Roy Wilkens (SOEST), Mike Richardson (Naval Research Lab, MS)
Measurement and modeling of geo-acoustic properties of carbonate sediments in Kane'ohe Bay, Hawai'i.
