This paper develops a framework for estimating potential Arctic kelp distribution and lower-depth biomass from seafloor irradiance. Using fjord-specific empirical relationships, it links standing stock estimates to light availability and its drivers, providing a baseline for tracking how changing coastal light environments may alter Arctic kelp biomass under ongoing environmental change.
