A 28-day experimental dataset examines the chronic effects of sediment-induced changes in light quality and quantity on three coral species and one sponge species. The data includes measurements of color, symbiont density, chlorophyll content, and lipid composition for organisms exposed to five different suspended sediment concentrations. The study was conducted using ecologically relevant turbidity and light profiles to inform thresholds for dredging operations.
Use Cases
- Modeling physiological stress thresholds for corals based on suspended sediment concentration and light profiles mentioned in the description.
- Analyzing the relationship between light spectral shifts and photosynthetic pigment content (chlorophyll a) in symbiotic organisms.
- Investigating lipid class composition (e.g., WAX, TAG) as an indicator of energy storage and stress response in marine invertebrates.
- Calibrating nephelometer readings (FNU) to gravimetric suspended sediment concentrations (mg L-1) for environmental monitoring.
Strengths
- Data is derived from a controlled 28-day experiment with five different nominal suspended sediment concentrations.
- Includes multiple physiological response variables: color, symbiont density, chlorophyll a content, and detailed lipid class analysis.
- Light profiles and sediment concentrations were based on ecologically relevant field data.
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 specimens collected from two specific islands.
