Note:
During extended periods of hypoxia in the lower water
layer of Onondaga Lake (when dissolved oxygen is < 2.0
mg/L), the dissolved oxygen probes at 12 meters and 15
meters are removed from the water quality instruments
to prevent damage.

|
The "NaN" (that is, "Not a Number") displayed in the
dissolved oxygen dial indicates that the measured
dissolved oxygen value is not available because the
probe has been removed.

Data obtained from Onondaga County's telemonitoring buoy is
transmitted on 15 minute intervals to a receiving
station at the Metropolitan Syracuse Wastewater Treatment Plant by radio frequency
transmissions. The data is received and automatically
processed for anomalous values through a software
program before it is transmitted to the web site for
viewing by the public.
Anomalous or incorrect data may still be transmitted,
caused by mechanical problems or invalid readings from
occurrences such as instrument fouling by biological
materials, instrument malfunction due to flotsam
and/or jetsam, unusually high battery drain, failure
of solar energy panels and/or radio frequency noise
transmitted with the data signal.
The data from the buoy (above) has not been reviewed
or validated by WEP staff and, therefore, is
considered to be provisional. WEP is not responsible,
nor does it assume any liability, for any damages
caused by inaccuracies in this data or documentation
or as a result of the failure of the software to
function in a particular manner.
WEP makes no warranty, expressed or implied, as to the
accuracy, completeness, or utility of this
information, nor does the fact of distribution
constitute a warranty. Final data will be published
yearly in the Onondaga Lake Monitoring Program's Annual
Report when issued by WEP.
