Shark Diet Stable Isotope Signatures from Northeast Pacific Coastal Habitats

White muscle tissue stable isotope signatures from sixgill and sevengill sharks in the Northeast Pacific. The data were used with mixing models to determine diet probabilities and predict predatory impact on prey groups across space and time. The dataset originates from the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling shark diet composition based on stable isotope signatures mentioned in the description.
• Assessing predatory impact on prey groups across daily, seasonal, and annual movement patterns.
• Characterizing the ecosystem role of sharks in coastal habitats.
• Initializing mixing models with prepared prey tissue data.

Strengths

• Data includes stable isotope signatures from two shark species (sixgill and sevengill).
• Prey species tissues were also prepared to initialize models.
• Dataset is associated with the National Oceanic and Atmospheric Administration.

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 bias inherent to the specified Northeast Pacific coastal habitats.
