Vertical distributions of in situ Chl a fluorescence and picoplankton abundance along Transects A and B in 0–3,000 m (1^st and 2^nd columns) and 0–300 m (3^rd and 4^th columns) water columns in the Caroline Seamount. Chl a (a‐d): in situ Chl a fluorescence; SYN (e‐h): Synechococcus , ×10³ cells/ml; PRO (i‐l): Prochlorococcus , ×10³ cells/ml; PEUK (m‐p): picoeukaryotes, ×10³ cells/ml; HP (q‐t): heterotrophic prokaryotes, ×10⁵ cells/ml.
