Table 2.
Significant correlations (bold numbers: p < 0.01, thin numbers: p < 0.05, ns: not significant) between the prokaryotic characteristics and activities (PA, PB, CDPR, LAP, GLU and AP) and the other variables, grouped for: physical-chemical (S, T, OX), POM quantitative (POC, PN, proteins and carbohydrates), POM qualitative (POC/PN ratio and protein/carbohydrate ratio). Correlations among the prokaryotic activity variables are also provided. Coastal TBN: n= 36, except for PA, PB, and GLU (n = 32). Offshore RS: n = 36.
