Mean fluxes were
131.4 190.7 mgCO2m2 h1 and 147.5 192.2 mgCO2m2 h1,
respectively, indicating a strong absorption of atmospheric CO2
(Fig. 4). At TD and TS, 5 cm and 10 cm sediment temperatures
showed a consistent response to changes in surface temperatures,
and their peaks occurred around January 4
