Directed Outflow Project water quality data

Water quality data from the ICF/USBR Directed Outflow Project.

DOP

a tibble with 3,473 rows and 16 variables

Source: Name of the source dataset.
Station: Station where sample was collected. Includes Station_Code and Habitat from the source dataset because multiple habitats are collected at each station.
Latitude: Latitude at start of zooplankton tow in decimal degrees.
Longitude: Longitude at start of zooplankton tow in decimal degrees.
Field_coords: Were lat/long coordinates collected in the field (TRUE), or do they represent the location of a fixed station (FALSE)?
Date: Date sample was collected.
Datetime: Date and time of sample collection.
Depth: Bottom depth at start of trawl (m).
Secchi: Secchi depth (cm).
Temperature: Temperature (°C) at surface.
Salinity: Salinity at surface.
Conductivity: Specific conductance (\muS cm^-1) at surface.
DissolvedOxygen: Dissolved oxygen (mg/L) at surface.
pH: pH (dimensionless) at surface.
TurbidityFNU: Turbidity (FNU) at surface.
Chlorophyll: Chlorophyll-a concentration (\mug L^-1) at surface.
