UK Marine Noise Registry: 2021 Underwater Noise Events

2021 data from the UK Marine Noise Registry maps impulsive underwater noise events across UK marine waters. Maps display the distribution, duration, and activity types of noise events between 10 Hz and 12 kHz, measured in pulse block days. The data is published by the Joint Nature Conservation Committee.

Use Cases

• Map the spatial distribution of underwater noise pollution based on the described pulse block day metric.
• Analyze the duration of impulsive noise events across the UK oil and gas licensing grid.
• Identify activity types contributing to marine noise based on the described registry categories.
• Assess temporal patterns of noise events for the calendar year 2021.

Strengths

• Data covers the full calendar year 2021 for UK marine waters.
• Noise events are mapped using a defined spatial grid (10 minutes latitude by 12 minutes longitude).
• Includes associated documentation and a data dictionary for interpretation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the UK reporting scope.
