UK Marine Noise Registry Outputs for 2015
This publication contains maps produced using data collated by 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 C20170329MNRPBDMapsCaveats2015UKEEZ.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 2015.
Noise events are shown in pulse block days (PBD).
A PBD is when at least one noise event (between 10 Hz and 10 kHz) has occurred within a block on a particular day.
Blocks refer to the blocks/quadrants delimited by the UK oil and gas licensing grid.
