This Bio Acoustic data was collected in April 2012 under the IMOS Ship of Opportunity (SOOP) Bio Acoustic (BA) program on Australian Wild Tuna's Santo Rocca (IMOS platform code: LFB13191P). Departed: Australia, April 26, 2012 Arrived: Australia, April 28, 2012 Bio acoustic signals allow understanding how mid-water prey species (known collectively as micronekton) such as small fish, squid, krill and jellyfish are distributed. Mid-water prey form the core of the ocean food web, transferring energy from primary producers at the ocean surface to top predators such as tunas, billfish, sharks, seals and seabirds.The mass and distribution of micronekton reflects broad-scale patterns in the structure and function of the ocean, as well as the dynamics of marine ecosystems. Acoustic mapping is done from fishing and scientific vessels that are equipped with scientifically-calibrated 38 kHz digital echo-sounders that record a slice of acoustic backscatter to a depth of 1500 meters.
