Burrard Inlet and Fraser River Delta in British Columbia are the locations for this dataset on epifauna and substrate estimates collected from floating dock perimeters between August and November 2020. The data, compiled by Meagan Mak, includes diversity estimates from video surveys across three depth zones and lists dock substrate types and observed species. Mussels provided a biological substrate, with coverage ranging between 46% and 95% across docks.
Use Cases
- Analyze species distribution across depth zones (splash, subsurface, deep-water) based on the video survey methodology.
- Study substrate preferences of epifauna based on the listed dock materials (wood, concrete, tires, plastic-floats, metal).
- Model mussel coverage as a biological substrate for other species based on the reported 46%-95% coverage range.
- Investigate the impact of episodic low-salinity intrusions on marine organisms at specific sites like Coast Guard Sea Island dock.
Strengths
- Includes detailed depth-interval definitions for three zones (SZ, SSZ, DZ) enabling stratified analysis.
- Lists a wide range of observed epifauna and epiflora species (anemones, tunicates, sponge, tube-worms, etc.).
- Provides specific quantitative ranges for mussel coverage (46%-95%) and frequency of occurrence (85%-100%).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
