Spatio-temporal variability of dissolved oxygen within the hyporheic zone of a freshwater pearl mussel bed

摘要：

　　The spatio-temporal variability of hyporheic dissolved oxygen (DO) was assessed in a river supporting Freshwater Pearl Mussels Margaritifera margaritifera. A combination of logging and hand held optical sensors were used to characterise DO at 5 cm depths in two reaches. DO was generally high (>80% saturation) and similar to streamwater at most locations for most of the one year monitoring period. Only in one location did temporal variability correspond to changes in discharge. There was considerable spatial variation in DO, with values ranging from close to zero t0 100 % saturation during summer low flow conditions (Q93).
