Water level is measured with acoustic water level gages that digitally record relative water height relative to the local soil surface. Dataset Purpose Our long term research program focuses on the following central objective: Regional processes mediated by water flow control population and ecosystem level dynamics at any location within the coastal Everglades landscape. This phenomenon is best exemplified in the dynamics of an estuarine oligohaline zone where fresh water draining phosphorus-limited Everglades marshes mixes with water from the more nitrogen-limited coastal ocean.

The recorders collect water level readings every hour. The data is collected from the water level recorder using an HP 48G+ calculator on a monthly basis. To make a daily water level reading, all numbers are downloaded into Microsoft Excel, and all the readings from a day are averaged. Water level data is then transformed from inches to centimeters by multiplying the numbers by 2.54. Data from 29-Aug-97 to 25-May-00 were collected using a Richards Type Water Level Recorder. From 31-Aug-00 to 12-Oct-00 both the Richards Type and Ultrasonic water level recorders collected water level data to calibrate data from the Richards Type Water Level Recorder. A regression of data from both recorders was performed to calibrate data from the Richards Type Water Level Recorder to the Ultrasonic water level recorder data. From June 2004, water levels are recorded using an Infinities Pressure water level gauge. The new device was calibrated to the values from the Acoustic before removal.

Then the data is checked for negatives (values given especially during dry season). Negatives that are found are converted to zeros (modified Find and Replace). Next the data is checked for peaks and valleys (values that are found to be excessively high or low). Before the data is averaged per day the last data check is to see if a negative number (now a zero) causes a peak or valley (which are deleted as a peak or valley). The next several formulas are used for these checks, averaging the data set, and anomoly investigation: [=IF({time}=0,AVERAGE({24 values}),"")], [=IF(COUNT({24 values})>=22,"",{date at zero time})], [=IF(COUNT(D8:D10)>=2,IF(OR(ABS(D8-D9)<2,ABS(D9-D10)<2,D9=""),""),"")], [=IF(ISNUMBER(D9),IF(D9<>0,"",IF(AND(ABS(D9-D8)<2,ABS(D9-D10)<2),"")),"")].
