Below is a map of the current mid-river water quality sampling stations. The Paerl Lab collects surface and bottom water from these stations on a bi-weekly basis. The water is then brought back to the lab where it is filtered for HPLC, chlorophyll a, CHN, CDOM, DOC/ DIC, and nutrients. YSI Sensor Sonde readings are also taken at each station.
The YSI measures water temperature, salinity, conductivity, chl a, dissolved oxygen, ph, and fluorescence. See below
