In the above article by A. Shiomoto et al., first published online on 3 August Reference Shiomoto, Asakuma, Hoon, Sakaguchi and Maekawa2011, the following errors were made. The article running heads were incorrect and should read EARLY SPRING BLOOM OF LARGE DIATOMS IN SAROMA-KO LAGOON. In Figures 3 and 5 the horizontal axis labels were incorrectly placed. In Figure 4A the numbers along the horizontal axes are misaligned and in Figure 4A and B the months of February, March and April are missing. The correct Figures 3–5 are displayed below.

Fig. 3. Vertical profiles of size-fractionated chlorophyll-a concentration (A) and chlorophyll-a size composition (B) in February, March and April. , <2 μm; □, 2–10 μm; ■, >10 μm. Figures in parentheses on the vertical axis show the depth in metres.

Fig. 4. Vertical profiles of primary production (A) and chlorophyll-a-specific primary production (B) in February, March and April. Figures in parentheses on the vertical axis show the depth in metres.

Fig. 5. Vertical profiles of cell numbers of diatom (A) and percentage contributions of Thalassiosira spp. (■), Chaetoceros spp. (□) and other diatoms () to total diatom cell numbers (B) in February, March and April. Figures in parentheses on the vertical axis show the depth in metres.
