Historic Secchi Depth Measurements for Light Climate Studies, 1931-1968

Cefas Historic Secchi Depth Measurements comprise 470 observations collected to study the effects of the light climate on pelagic fish. The data was gathered in discrete years: 1931, 1937, 1946-1950, and 1968. The dataset is provided by the Government Digital Service via the eu_open_data platform.

Use Cases

• Modeling historical light penetration in marine environments based on Secchi depth measurements.
• Analyzing the relationship between water clarity and pelagic fish school positioning mentioned in the description.
• Establishing baseline water quality conditions for long-term environmental change studies.

Strengths

• Contains 470 specific measurements.
• Provides a historical time series spanning several decades from 1931 to 1968.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
