Underwater surveys using subdivided quadrats collected data on the grazing effect of sea urchins on macroalgal communities. The dataset, hosted by the Australian Ocean Data Network, shows the relationship between sea urchin numbers and algal cover in the Western Mediterranean. It was last updated on 2026-06 04.
Use Cases
- Modeling grazing pressure on macroalgal communities based on sea urchin abundance data.
- Analyzing spatial relationships between herbivore density and algal cover from quadrat survey data.
- Investigating ecosystem dynamics and potential trophic cascades in the Western Mediterranean.
Strengths
- Data collection method is specified as several underwater surveys using subdivided quadrats.
- The dataset's relationship focus is clearly defined: sea urchin numbers versus algal cover.

Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Description metadata is limited; actual data quality requires manual inspection after download.
