Site Description:
Approximately half a mile offshore of Jefferson Patterson Park, Calvert County, Maryland in the Patuxent River in about 10 meters of water. Location:   38 23.32 N   76 31.59 

Water Quality Sensors:
Water quality parameters are measured by YSI 6600 multi-parameter datasondes positioned approximately 1 meter (3 feet) below the surface and 1 meter (3 feet) above the bottom.  Each datasonde measures temperature, depth, conductivity, salinity, dissolved oxygen, chlorophyll and turbidity.

Meteorological Station:
Meteorological data are collected using a YSI 6213 MET suite located 4 meters (12 feet) above the surface of the river.  This suite incorporates a wind sensor that measures wind speed and direction, a temperature sensor, and a relative humidity sensor.  Solar radiation is monitored by a Li-Cor LI200SZ sensor mounted at approximately 3.75 meters (11 feet) above the surface.  Atmospheric pressure is recorded from a Coastal Environmental MAZ6217 Barometric Pressure sensor located in a protective case 1 meter (3 feet) above the water surface

Sample Timing :
All data are collected at 15 minute intervals
