Click on any date for view of entire water column. Sensor history: Please note that the dissolved
oxygen data from 7/1/05 10 am through 8/2/05 1 pm,
through 8/23/06 10
am, and 2/12/07 12 am through 2/20/07 11 am should
be treated as suspect due to sensor failure. The conductivity sensor was replaced at 11 am on 9/16/2010
and the pH sensor was replaced at 1 pm on 10/26/2010. The phycocyanin sensor was replaced
at 11 am on 3/8/2011.
Due to seasonal low dissolved oxygen and high hydrogen sulfide precipitation on the sensors at depths greater than 3-4 meters, dissolved oxygen data during the summer of 2014 was compromised. The water quality sensors were reconfigured for these conditions to give a more accurate representation of the ambient conditions.
Please note that the phycocyanin sensor has failed and will be repaired as soon as a replacement sensor is obtained.
