Algal turf sediment dynamics across the Florida Reef Tract

Algal turfs on the northern Florida Reef Tract support consistently high sediment loads (1,445–16,639 g m-2) across nearshore to outer reef positions.

• Why it matters: Quantifying algal turf sediments across reef shelves is limited for Western Atlantic systems, even though these turfs drive key processes on degraded reefs.
• What they did: At three locations along the northern Florida Reef Tract, researchers measured algal turf length, sediment loads, and grain-size distributions across nearshore, inner, middle, and outer reef positions.
• The result: Sediment loads were positively associated with turf length and generally declined offshore; nearshore turfs were 1.6-fold longer and had 1.6-fold higher sediment loads than outer reefs, with offshore sediments shifting to finer grains.
