North Atlantic data from ship-board experiments examines the role of food quality, including carbon, nitrogen, and fatty acid content, in regulating egg production of the copepod Calanus finmarchicus. Complementary tracer experiments investigate the organism's ability to synthesize essential fatty acids. The dataset was produced by SCIOPS, with experiments conducted during spring and autumn Marine Productivity cruises.
Use Cases
- Model egg production rates based on in situ food carbon and nitrogen content using stoichiometry theory.
- Analyze the relationship between specific fatty acid concentrations in food and copepod reproductive output.
- Investigate Calanus finmarchicus's ability to synthesize essential fatty acids through labeled tracer experiment data.
- Compare seasonal (spring vs. autumn) variations in nutritional regulation of egg production from cruise data.
Strengths
- Data underpinned by quantitative stoichiometry theory (Anderson and Pond, 2000).
- Experiments designed with complementary ship-board approaches: in situ feeding and labeled tracer studies.
- Sampling conducted across multiple seasons (spring and autumn cruises).
Limitations
- Specific sample size (row count) and measured column features are unknown.
- Geographic coverage is limited to specific North Atlantic cruise tracks.
- Temporal coverage and dataset recency are unspecified.
