WAT-SylvaniaDamIpswich-DO-2015_xls

Methods: 

Dissolved oxygen and water temperature were measured using a HOBO datalogger secured inside a perforated PVC pipe attached to the south dam abutment.

Dissolved oxygen percent saturation was calculated using HOBOware software and barometric pressure data from Marshview Farm.

NOTES AND COMMENTS:
HOBO dissolved oxygen loggers have a sensor cap that requires replacement every 7 months. If the logger is deployed when the sensor cap expires, no usable data is collected after that point.

FLAGS:
1 -- Datalogger not deployed
2 -- Datalogger was deployed but with an expired sensor cap

Maintenance:
