Relationships between physical, chemical and biological variables in seawater and SPM for which significant correlations were found (Pearson product-moment correlation, P < 0.05). (A) PON flux vs POC flux, (B) BGase activity vs LAPase activity, (C) LAPase activity vs POC flux, (D) BGase activity vs POC flux, (E) HBPSPM vs water temperature, and (F) Lipase activity vs HBPSPM. The regression line in (F) was determined after excluding one outlying data point.
