Estimated carbon turnover rates within the TEP-C pool. Turnover rates per day were calculated as the ratio of C remineralization rates (µg C L–1 d–1) to TEP-C (µg C L–1). See text for more details. Note that differences in the deep-water treatments (but not in the surface-water treatments) were significant (Student’s t-test, p < 0.05). DOI: https://doi.org/10.1525/elementa.371.f5
