dc.description.abstractThe biochemical compositions (proteins, carbohydrates, and lipids) of phytoplankton provide useful information for their environmental growth conditions and nutritional status as a basic food source for upper trophic consumers. Concentrations of these compositions were assessed at 100, 30, and 1% light penetration depths within the euphotic zone in the Amundsen Sea, Antarctica, using colorimetric techniques. The major inorganic nutrients were generally abundant throughout the study area. The average chlorophyll a (chl-a) concentration was 49.2 mg m A 2 (S.D.¼ 7 27.6 mg m A 2 ) and large phyto- plankton ( 420 mm) accounted for 64.1% of the total chl-a concentration. The biochemical compositions of the phytoplankton were not signi?cantly different among different light depths or productivity stations. The overall compositions of proteins, carbohydrates, and lipids from all stations averaged 65.9% (S.D. ¼ 712.5%), 22.4% (S.D.¼ 710.9%), and 11.7% (S.D. ¼ 7 6.5%), respectively. Regardless of dominant phytoplankton species, nitrogen-abundant conditions sustained high protein compositions of phyto- plankton in the Amundsen Sea during the cruise period. Based on the macromolecular compositions, the average food material (FM) concentration was 219.4 μg L A 1 (S.D.¼ 7151.1 μg L A 1 ) and correlated positively with the primary productivity in the Amundsen Sea. High protein/carbohydrate ratios (4 1) and large proportions of proteins suggest that phytoplankton provide nitrogen-suf?cient foods to higher trophic consumers through a higher ef?ciency of protein carbon incorporated into herbivores.-
