Marine Environmental Data & Information Network provides records of the years and locations of first occurrence for marine non-indigenous species in UK waters. The data covers the OSPAR regions of the Greater North Sea and Celtic Seas for the assessment period from 2003 to 2020 inclusive. These data are used for analysis under the UK Marine Strategy Indicator Assessment 2024.
Use Cases
- Track the rate of new non-indigenous species introductions based on first occurrence records.
- Analyze spatial patterns of species arrivals based on location data across OSPAR regions.
- Support marine strategy indicator assessments based on the count of new introductions over time.
Strengths
- Covers a defined 18-year assessment period from 2003 to 2020.
- Focuses on first occurrence records, which are critical for tracking new introductions.
- Geographically scoped to two specific OSPAR marine regions: the Greater North Sea and Celtic Seas.
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 temporal and geographic bias inherent to the collection methodology.
