Assessing Sub-Antarctic Zone primary productivity from fast repetition rate fluorometry
In situ primary productivity(PP)in the Sub-Antarctic Zone(SAZ)and the Polar Frontal Zone (PFZ)south of Australia was estimated using fast repetition rate fluorometry(FRRF).FRRF-derived PP at Process station 3(P3)southeast of Tasmania(461S, 1531E) were higher than P1inthe southwest of Tasmania(461S,...

In situ primary productivity(PP)in the Sub-Antarctic Zone(SAZ)and the Polar Frontal Zone (PFZ)south of Australia was estimated using fast repetition rate fluorometry(FRRF).FRRF-derived PP at Process station 3(P3)southeast of Tasmania(461S, 1531E) were higher than P1inthe southwest of Tasmania(461S, 1401E) and P2 in the Polar Frontal Zone (541S, 1461E). The FRRF-derived PP rates were wellcorrelated with 14C-uptake rates fromone-hour incubations(r20.85,slope1.2370.05, po0.01,n85) but the relationship between both methods differed vertically and spatially.
