Within the ice bottom, ice algae begin their annual Arctic spring bloom in which they contribute up to half of the total annual primary production in the central Arctic Ocean. Essential fats (or lipids) are produced during the early portion of the ice algal bloom (e.g., polyunsaturated fatty acids (...
