Habitat suitability models for phototrophs for a section of central Great Barrier Reef.

<p>(a) GEO; (b) GEO-ENV; (c) ENV; and (d) BEST.</p

Estimated habitat area for phototroph and heterotroph communities using both Lowest Presence (LPT) and 10^th Percentile thresholds in square km (km²).

<p>GEO indicates the total area estimated.</p

Predictions of phototroph communities in the Hydrographers Passage region, central Great Barrier Reef.

<p>GEO only and GEO-ENV both predicted suitable habitat along the outer-self, although model results were more accurate in areas with multibeam (right hand side) compared to singlebeam echosoundings (left). GEO also predicted higher habitat suitability on the deeper flanks of emergent reefs inside the GBR lagoon.</p
