Process and seasonal context
- Definition
- Transfer of marine organic matter to beach food webs through stranded algae and other wrack.
- Drivers
- water flow; animal movement; wind; waves; habitat connectivity
- Inputs
- water; nutrients; organisms; organic matter; sediment
- Outputs
- subsidies; downstream effects; cross-realm coupling
