Local human pressures modulate turf sediment loads in a warm-temperate oceanic island.

In the Anthropocene, algal turfs are expected to replace macroalgal forests and coral cover as the dominant benthic state. These turf seascapes play a key role in regulating ecosystem processes through sediment retention, which carries significant ecological and socio-economic implications. However, our understanding of sediments trapped by turf on coastal reefs, particularly in oceanic islands, remains limited.
