JNCC Report 755A: Compliance with JNCC guidelines during geophysical surveys in UK waters between 2011 and 2020 and long-term trends in compliance; JNCC Report 755B: Marine mammal observations during geophysical surveys from 1995–2020 2024

Abstract

JNCC Report 755 comprises two resources, report 755A (Compliance with JNCC guidelines during geophysical surveys in UK waters between 2011 and 2020 and long-term trends in compliance), and report 755B (Marine mammal observations during geophysical surveys from 1995–2020).

JNCC Report 755A outlines data from 796 geophysical surveys on the UKCS between 2011 and 2020, which were checked and corrected. Data from all or part of 740 surveys were of suitable quality for inclusion in the database. Compliance with the mitigation measures contained in the JNCC guidelines for geophysical surveys was assessed for surveys with airguns and for high resolution surveys (defined here as those using high resolution sources other than airguns). Consent conditions were considered where appropriate when assessing compliance.

JNCC Report 755B examines data from 1,940 geophysical surveys in UK and adjacent waters between 1995 and 2020, to assess the effects of geophysical operations on marine mammals. Over 345,000 hours were recorded as monitoring for marine mammals (over 283,000 hours visual monitoring and over 62,000 hours acoustic monitoring), with acoustic sources being active for 49% of this time. Acoustic sources included airguns and high-resolution sources such as sub-bottom profilers.
