TABLE 3.

Ratio of counts in methane and CO₂ produced from the degradation of [2-¹⁴C]acetate at different depths of sediment core taken from Orange Pond at 60 cm below the waterline

Depth (cm)	14CH4 (102 dpm · h−1)a	14CO2 (104 dpm · h−1)a	poxb
0–2	0.09	1.05	0.99
2–4	0.18	0.88	0.99

^aDetermined over a time course of 240 h in which production of ¹⁴CO₂ and ¹⁴CH₄ was linear. 

^bp_ox = ¹⁴CO₂/(¹⁴CO₂ + ¹⁴CH₄).
