Marine mammal observations during seismic surveys from 1994–2010 2015


The aim of the analysis was to identify any effects of seismic operations on marine mammals and any long-term trends in compliance with the JNCC guidelines. The analysis focused on general trends in survey effort and species distribution; detection rates, closest distance of approach to the airguns, behaviour and the effectiveness of the soft start (all comparing airguns firing versus not firing) and general trends in compliance with JNCC's seismic guidelines.

Please note JNCC Report No. 463b (Implementation of and consideration for revisions to the JNCC guidelines for seismic surveys) accompanies this report (JNCC Report No. 463a).
