Historical UK Marine Biological Survey Data from 1902 to 1970s

Cefas (formerly Directorate of Fisheries) collected station and biological data during research surveys in UK seas, primarily the North Sea, starting in 1902. The data spans multiple decades but lacks records from both World Wars and exhibits variations in species recording protocols over time. Surveys occurred in each season, though gear and methods were not standardized throughout the long-term series.

Use Cases

• Analyzing long-term population trends for key commercial species like Plaice, Sole, and Cod based on the systematic recording mentioned.
• Studying historical changes in marine biodiversity and survey methodology based on the described shifts in recording protocols.
• Modeling spatial distribution of fish species in the southern and central North Sea based on the described survey haul locations.
• Investigating the impact of major historical events on fisheries data collection based on the noted gaps during the World Wars.

Strengths

• Data collection began in 1902, providing a long-term historical perspective.
• Surveys were conducted in each season, offering intra-annual temporal coverage.
• Covers a specific geographic area, focusing on seas around the UK, especially the North Sea.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data collection protocols and gear were not standardized over the long series, affecting consistency.
• Systematic recording of all species was not maintained throughout the entire time period.

Provenance

Source

Cefas (Centre for Environment, Fisheries & Aquaculture Science), formerly the Directorate of Fisheries.

Collection Method

Research survey hauls conducted in seas around the UK, not on a systematic grid.

Time Range

1902 to the 1970s, with gaps during both World Wars.

Freshness

Data collection ended in the 1970s; the dataset is historical.

Geography

Seas around the UK, mostly in the North Sea, especially southern and central areas.
