Acoustic extinction in dense herring layers, measured from a bottom-mounted transducer
Utne, Kjell R.; Ona, Egil (ICES CM documents, Working paper, 2006)Herring is often found in dense aggregations or schools, and acoustic shadowing is thus a problem in acoustic survey estimates. Knowledge of the attenuated echo intensity in herring aggregations is essential for correcting ... -

Relative importance of fisheries, trophodynamic and environmental drivers in a series of marine ecosystems
Fu, Caihong; Gaichas, Sarah; Link, Jason S.; Bundy, Alida; Boldt, Jennifer L.; Cook, Adam M.; Gamble, Robert; Utne, Kjell R.; Liu, Hui; Friedland, Kevin (Journal article; Peer reviewed, 2012-07-12)Marine ecosystems are influenced by drivers that operate and interact over multiple scales, resulting in nonlinear or abrupt responses to perturbation. Because of the inherent complexity of marine ecosystems, progress ... -
Trophic-level determinants of biomass accumulation in marine ecosystems
Pranovi, Fabio; Link, Jason S.; Fu, Caihong; Cook, Adam M.; Liu, Hui; Gaichas, Sarah; Friedland, Kevin; Utne, Kjell R.; Benoît, Hugues P. (Journal article; Peer reviewed, 2012-07-12)Metrics representative of key ecosystem processes are required for monitoring and understanding system dynamics, as a function of ecosystem-based fisheries management (EBFM). Useful properties of such indicators should ... -
