UK Marine Noise Registry: 2021 outputs 2023
This publication contains maps, associated data tables and shapefiles from the 2021 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 MNRPBDMapsCaveats2021_UKEEZ.docx and refer to the data dictionary, DataDictionary_2021.xlsx.
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 2021.
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, multibeam echosounders up to 12kHz) has occurred within a block on a particular day.
