An in situ incubation method for measuring the productivity and responses of under‐ice algae to ocean acidification and warming in polar marine habitats
Abstract During the Antarctic spring, algae grows under extensive areas of sea‐ice and is a fundamental source of primary production. Understanding how under‐ice (bottom‐ice) algae will be affected by ocean warming and acidification is critically important in determining the probable future flow‐on...
