A technique for deploying multiprobe data loggers to measure shallow waterparameters

Low oxygen events have been suggested as causative factors for the reductio n of the eastern oyster, Crassostrea virginica in Bon Secour Bay, Alabama. Because younger C. virginica may be less resistant to low oxygen levels whi ch more often occur near the substrate, the height above the substrate may play an important role in their survival. To investigate the effect of low oxygen on the growth and mortality of C. virginica, a series of multiprobe data loggers were deployed in conjunction with C. virginica beds at differe nt heights above the substrate. A simple and inexpensive method for deployi ng multiprobe data loggers at a defined height above the substrate in shall ow bodies of water is discussed. (C) 2000 Elsevier Science B.V.
