Abstract: | This study assessed the possibility of using drift and subtidal seaweeds from St Lawrence Island, Alaska (lat. 63°N) for sale
by the native population after simple processing. Over 125 km of coastline were surveyed for distribution of both drift and
subtidal seaweeds. Drift seaweed wet weight densities ranged from 0.2 to over 9 kg m−2, with an average of over 4 t km−1 in the areas sampled. Attached, benthic seaweed densities ranged from 0.15 to 0.32 kg m−2. Thirty and 35% of the biomass was composed of Agarum cribrosum and species of Laminaria, respectively, both as drift and as benthic seaweed. Data from tagged Laminaria indicated that growth rates were relatively slow for most of the year. The drift seaweed resource on the coasts south and
west of the city of Gambell appeared to have good potential for a small-scale commercial harvest.
