Antarctic Krill Exoskeleton Thickness and Organ Volume Measurements

Comprising optical coherence tomography (OCT) imaging data from post mortem Antarctic krill (Euphausia superba) samples. It provides measurements of physiological features, including an average exoskeleton thickness of (30±4) µm along a 1 cm body length and a heart volume estimate of (0.73±0.03) mm³. The data was generated by Nicola Bellini to demonstrate OCT's application for non-invasive biological imaging.

Use Cases

• Analyze the relationship between krill exoskeleton thickness and body length segments using OCT-derived measurements.
• Estimate organ volumes, such as heart volume, from detailed internal structural imagery of krill specimens.
• Apply OCT imaging techniques to study the internal morphology of pleopod joints in marine crustaceans.
• Use high-resolution subsurface imagery to track morphological changes in krill under simulated environmental conditions.

Strengths

• Provides quantitative physiological measurements, including a specific average exoskeleton thickness of (30±4) µm.
• Includes a precise heart volume estimate of (0.73±0.03) mm³ derived from OCT imaging.
• Demonstrates the application of a high-resolution, non-invasive optical imaging technique (OCT) on krill.

Limitations

• Data is from post mortem samples, limiting direct observation of live animal responses over time.
• Sample size and specific row/column counts are unknown, which may affect statistical power.
• The dataset's temporal and geographic coverage for the krill samples is not specified.
