Temperate reef habitat structure data
The data is a collection of reef habitat structure measurements from sites around Tasmania with regional snapshots from Jurien Bay (WA) and Jervis Bay (NSW).
Explanatory variables investigated were depth, duration of protection from fishing within marine protected area, rugosity, boulder substratum at a site, the average number of refuge size categories, and a fractal refuge index that reflected the frequency distribution of different sized physical refuges. Also considered were biogenic habitat structure in the form of the percent cover of canopy algae and the biomass of predatory fish.

- Purpose
- Determine the influence of reef habitat structure on the response of fished and unfished mobile invertebrates to marine protected areas in temperate Australia. Determine broad spatial scale correlations between substratum habitat structure and mobile macroinvertebrate populations and communities. Survey strategy designed to link with Barrett and Edgar's long-term and broad-scale invertebrate datasets.

- Statement
- Each site consists of measurements across 1 x 200 m (divided into four 50 m subtransects) of reef at the 5 m (and occasionally 10 m) depth contour. % cover of substratum cover types (consolidated bedrock, sand, cobbles < 0.2 m, and boulder size categories 0.2 - 0.5, 0.5 - 1.0, > 1 m) estimated. Average substratum height change was estimated and maximum substratum height change over 1 m horizontal distance measured. The density of 'refuges' (holes, crevices, corners) were subsampled in two 1 x 5 m blocks on each transect. Linear rugosity (contour/linear distance) and the height of substratum overhangs were also subsampled in two random 5 m sections of transect. More detailed measurements carried out at 12 sites in Mercury Passage included fine scale single beam acoustics and spatially nested reef surface profiles at 1 m, 10 cm and 1 cm intervals.
