Willis Wharf Water Quality Data
Most recent data readings:
Surface level temperature, salinity, dissolved oxygen, pH, turbidity, chlorophyll, and BGA-PE measurements are recorded every 15 minutes and are displayed here (see table below for parameter descriptions).
These graphs have not been subjected to VIMS ESL quality control. Questionable readings, outliers, missed readings, or gaps in the dataset may appear.
Raw and/or archived data files are available upon request. For requests, questions, or suggestions about the water quality data available, please contact Darian Kelley. (dkelley@vims.edu, 757-787-5836).
More information about our monitoring stations can be found on the ESL Water Quality Monitoring homepage.

Description |
Water Temperature |
◦C |
Measurement of the ambient water temperature.
|
Salinity |
ppt | Measurement of the amount of salt dissolved in a water sample. |
pH |
- | Numeric scale used to specify the acidity or basicity (alkalinity) of an aqueous solution. [acidic 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 basic]; 7 is neutral pH |
Optical Dissolved Oxygen |
mg/L | Measurement of the amount of oxygen that is present in the water, measured by the number of milligrams of oxygen dissolved in a liter of water. |
Turbidity |
NTU | Measurement of water clarity based on the size and quantity of particles present. |
Chlorophyll |
ug/L | Measurement of chlorophyll a contained in photosynthetic plants and organisms. |
BGA-PE |
ug/L | Measurement of the phycoerythrin accessory pigment found in blue-green algae (cyanobacteria). |
