Description

General Metadata for Chalgrove Lake YSI Data

Files

Specific metadata for each deployment can be found as text files with the file format of:

BC_chalgrove_lake_YYYY-MM-DD_YYYY-MM-DD_metadata.txt

Where YYYY-MM-DD_YYYY-MM-DD is the date range of the deployment.

File Created

  • 2019-04-12 by KF

File Modified

  • 2019-10-31 by KF - added the descriptions of the total algae variables
  • 2022-05-04 by KF - updated to match LEO standards and current deployment specs
  • 2022-05-23 by KF - updated to include Total Algae Sensor information

Description

These data are from a YSI EXO2 multiparameter sonde deployed at approximatly 0.7 m in Chalgrove Lake (37.242983 N, -78.464116 W) in approximately 4 m of water.

Sonde Specifics

The specific sensors and SNs deployed are on the metadata specific to each deployment but generally the sonde has:

  • Temperature
  • Conductivity
  • pH
  • ODO
  • Turbidity
  • Total Algae

Measurement Parameters, units, and Variable Names

  • date.time = the combined date and time of the measurement (YYYY-MM-DD HH:MM:SS)
  • date = the sampling date reported by the YSI (M/D/YYYY)
  • time = the sampling time reported by the YSI (HH:MM:SS)
  • frac_sec = the sampling fractions of a second reported by the YSI
  • site_name = the site name on the YSI deployment (left blank)
  • Cond = the conductivity (uS/cm)
  • Chl_RFU = the raw fluorescence of the chlorophyll sensor (RFU)
  • nLF_Cond = the nLF conductivity (uS/cm)
  • DO_perc = the percent oxygen saturation
  • DO_percL = the percent local oxygen saturation
  • DO_mgL = the dissolved oxygen concentration (mg/L)
  • SAL = the salinity (psu)
  • SPC = the specific conductivity (uS/cm)
  • TAL_PC_RFU = the raw fluorescence of the phycocyanin (blue green algae) sensor (RFU)
  • TDS = the total dissolved solids (mg/L)
  • Turbidity = the turbidity of the water (FNU)
  • TSS = the total suspended solids
  • pH = the pH
  • pH_mV = the millivolts of the pH sensor
  • Temp = the temperature (dC)
  • Batt_V = the battery voltage
  • Cable_V = the cable power
