Often numerous in number, highly visible on aerial photographs. Dense patches of seagrass in a matrix of sparse seagrass. Depressional features with deep sediment allow denser development of seagrasses than on surrounding bottoms where only a thin layer may be present. May be difficult to discern on aerial photographs from seagrass patches in hardbottom. May occur more in deeper water or protected bays.
Large sand features with recognizable seagrass patches.
Similar location to seagrass with blow-outs. Substrate may vary from sand to mud, and algae, either fixed or drift, may be a significant component. Offshore features tend to be more sandy, and inshore protected areas tend to be muddier in composition. Largely MacroAlgal cover with scattered seagrass patches. Scattered seagrass patches are a significant habitat component, but dominant is background of macroalgae.
