Cefas electronic data storage tag database contains temperature and depth records from tags attached to cod in the southern North Sea between 1999 and 2009. Data from recaptured fish were downloaded, with depth time series used to estimate daily geographic location. This dataset is one of 17 Cefas data sources assembled for a data paper.
Use Cases
- Modeling fish movement and migration patterns based on estimated daily locations.
- Analyzing the relationship between seawater temperature and fish depth preferences.
- Studying long-term environmental changes in the North Sea using a decadal temperature record.
- Validating oceanographic models with in-situ temperature and depth measurements from tagged fish.
Strengths
- Data spans a decade (1999-2009), providing a long-term perspective.
- Records originate from 17 distinct Cefas data sources assembled for a formal data paper.
- Depth time series was used to estimate daily geographic location, adding spatial context.
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_data platform and the specific tagging study.
