Prediction of krill swarm characteristics off East Antarctica
Entry ID: AAS_4311_krill_swarms


Summary
Abstract: This dataset contains estimates of krill swarm characteristics from statistical models based on underway acoustic observations along with underway and remote-sensed environmental data. Estimates of internal swarm density and depth across the study region (60-80 degrees E) are included for the time of the survey (Feb 2006). Estimates of February internal swarm density across the broader East Antarctic region (30-120 degrees E) are also included for the period 2001-2010.

Purpose: The acoustic data were collected during the multi-disciplinary Baseline Research on Oceanography, Krill and the Environment (BROKE)-West survey off East Antarctica in the austral summer of 2006 (Nicol et al. 2010). We used the easternmost half of the BROKE-West survey transects (T7-11) covering 60-80 degrees E.

Individual krill swarms were isolated by applying the schools detection algorithm of ... View entire text
