Floating Instrument Platform (FLIP)
Floating Instrument Platform (FLIP)
        The FLIP, or FLoating Instrument Platform, is a vessel unique to Scripps. With no engine noise and the ability to be stationed in one location for long periods of time, this vessel allows us to obtain concurrent passive acoustic and visual recordings of marine mammals as they pass undisturbed. For the last four years, FLIP has been deployed for up to 5 weeks near San Clemente Island in the Southern California Bight, close to a shipping lane and to the Navy SCORE range. This location is ideal for monitoring natural behavior and habitat use, as well as observing any reactions to ship traffic or noise.

        Multiple hydrophone arrays are deployed from FLIP, with sampling frequencies up to 200 kHz. The use of multiple time-synched arrays allows us to localize vocalizing cetaceans in three dimensional space. In addition, one or more HARP’s are deployed 1 km from FLIP.

Objectives: 1. Compare visual and acoustic detection range for odontocetes
                   2. Track individual groups of animals with acoustic arrays and with sightings
                   3. Record the behavior of all groups
                   4. Map prey field in the vicinity of FLIP
                   5. Observe impact of Navy sonar on animal behavior
