This publication contains maps, associated data tables and shapefiles from the 2016 data in the UK Marine Noise Registry (MNR; https://mnr.jncc.gov.uk/).
When using and/or interpreting the MNR output maps and spatial data, users should take into account the caveats in the enclosed document C20180413_MNRPBDMapsCaveats2016_UKEEZ.docx.
These maps display the distribution and duration of impulsive underwater noise events and the associated activity types contributing to these events, across UK marine waters, for the calendar year beginning January 1st 2016.
Noise events are mapped in pulse block days (PBD), using the UK oil and gas licensing grid, which consists of a series of blocks measuring 10 minutes latitude by 12 minutes longitude. A PBD is when at least one noise event (between the frequencies of 10 Hz and 10 kHz) has occurred within a block on a particular day.
