Figure 1

Sampling sites in the Yeongheung-do coastal waters, Incheon, Korea. St. 1: Site 1. St. 2: Site 2. St. 3: Site 3

Figure 2

Physicochemical factor fluctuations at St. 1 through St.3 during field monitoring. A: Temperature; B: Salinity; C: pH; D: Dissolved oxygen (DO); E: Chlorophyll a, note the y axis break in E: Break from 0.6 to 0.8

Figure 3

Nutrient variations at St. 1 through St. 3 during field monitoring. A: Phosphate; B: Ammonia; C: Nitrite; D: Nitrate; E: Silicate; F: N:P ratio; the dotted N:P line represents a value of 16, which is the nitrogen to phosphorus ratio in the plankton and is remarkably similar to the global ocean dissolved nitrate to phosphate ratio (16:1) (Redfield 1958)

Figure 4

Bacteria, dissolved organic carbon (DOC) and phytoplankton variations at St. 1 through St. 3 during field monitoring. A: Bacteria abundance; B: DOC concentration; C: phytoplankton abundance

Figure 5

DGGE band patterns (negatively converted) obtained from the 2013 field monitoring campaign in Yeongheung-do, Incheon, Korea. 1. 08-27-2013 St. 1- Surface; 2. 08-27-2013 St. 1 - Bottom; 3. 08-27-2013 St. 2 - Surface; 4. 08-27-2013 St. 2 - Bottom; 5. 09-24-2013 St. 1 - Surface; 6. 09-24-2013 St. 1 - Bottom; 7. 09-24-2013 St. 2 - Surface; 8. 09-24-2013 St. 2 - Bottom; 9. 10-29-2013 St. 1 - Surface; 10. 10-29-2013 St. 1 - Bottom; 11. 10-29-2013 St. 2 - Surface; 12. 10-29-2013 St. 2 - Bottom

Figure 6

DGGE pattern clustering analysis using the unweighted pair-group method with arithmetic means (UPGMA) for samples collected from St. 1 to St. 3 during the 2013 field monitoring campaign. Distinct background colors used to distinguish the months in different clades.

Figure 7

Redundancy analysis (RDA) of field monitoring data for physicochemical and biotic factors. A significant relationship existed between DOC and bacterial abundance. Cumulative percentage variance of the first two axes was 70.64% and 73.79%, respectively.
