<p># General Metadata for Chalgrove Lake YSI Data&nbsp;</p> <p>## Files</p> <p>Specific metadata for each deployment can be found as text files with the file format of:</p> <p>&nbsp; &nbsp; chalgrove_lake_DDMonthYYYY_metadata.txt<br> &nbsp; &nbsp;&nbsp;<br> Where DDMonthYYY is the date that the deployment ended.</p> <p>## File Created</p> <p>&nbsp; * 2019-04-12 by KF<br> &nbsp;&nbsp;<br> ## File Modified</p> <p>## Description</p> <p>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.</p> <p>## Sonde Specifics</p> <p>&nbsp; The specific sensors and SNs deployed are on the metadata specific to each deployment but generally the sonde has:<br> &nbsp;&nbsp;<br> &nbsp; * Temperature<br> &nbsp; * Conductivity<br> &nbsp; * pH<br> &nbsp; * ODO<br> &nbsp; * Total Algae<br> &nbsp;&nbsp;<br> ## Measurement Parameters, units, and Variable Names</p> <p>&nbsp; * date.time = the combined date and time of the measurement (YYYY-MM-DD HH:MM:SS)<br> &nbsp; * date = the sampling date reported by the YSI (M/D/YYYY)<br> &nbsp; * time = the sampling time reported by the YSI (HH:MM:SS)<br> &nbsp; * fract_sec = the smapling fractions of a second reported by the YSI<br> &nbsp; * site_name = the site name on the YSI deployment (left blank)<br> &nbsp; * cond = the conductivity (uS/cm)<br> &nbsp; * nLF_cond = the nLF conductivity (uS/cm)<br> &nbsp; * perc_ODO = the percent oxygen saturation<br> &nbsp; * perc_local_ODO = the percent local oxygen saturation<br> &nbsp; * ODO_conc = the dissolved oxygen concentration (mg/L)<br> &nbsp; * sal = the salinity (psu)<br> &nbsp; * sp_cond = the specific conductivity (uS/cm)<br> &nbsp; * TDS = the total dissolved solids (mg/L)<br> &nbsp; * pH = the pH<br> &nbsp; * pH mV = the millivolts of the pH sensor<br> &nbsp; * temp = the temperature (dC)<br> &nbsp; * battery = the battery voltage<br> &nbsp; * cable_pwr = the cable power<br> &nbsp;</p>
