Continuous daylight in the high-Arctic summer supports high plankton respiration rates compared to those supported in the dark

Abstract Plankton respiration rate is a major component of global CO2 production and is forecasted to increase rapidly in the Arctic with warming. Yet, existing assessments in the Arctic evaluated plankton respiration in the dark. Evidence that plankton respiration may be stimulated in the light is...
