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
