Dataset

IMOS - Ships of Opportunity – Bioacoustics - Data from Sealord F.V. Janas in the Tasman Sea from the 24th of June 2011 to the 28th of June 2011.

This Bio Acoustic data was collected in June 2011 under the IMOS Ship of Opportunity (SOOP) Bio Acoustic (BA) program on Sealord F.V. Janas (IMOS platform code: ZMTW). Departed: Hobart, Australia, June 24, 2011 Arrived: New Zealand, June 28, 2011 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.
