Table 3. Estimate of daily gross primary production (GPP), respiration (R) and net ecosystem production (NEP) integrated over the upper photic layer of Dziani Dzaha, expressed as g O₂ m^-2 d^-1.

		GPP	R	NEP	P/R
optodes in situ	day 1	22.2	-20.3	1.97	1.09
	day 2	17.3	-18.2	-0.90	0.95
PSOE	optimal	19.4	-11.4	8.09	1.70
	upper limit	24.6	-11.4	13.3	2.16
	lower limit	14.4	-11.4	3.0	1.26

Staehr et al. [23] method was used to fit optode in situ measurements, whereas Bright and Walsby [49] method was used to model production integral according to laboratory photosynthetic oxygen evolution (PSOE) measurements.
