Environmental sensor data describing Palau lake environments, 2011-2015. Reported parameters include depth, temperature, conductivity, salinity, oxygen, pH, light, and chlorophyll.
* NOTE: The P.I.'s are using this dataset to write papers. Please contact them before using these data to make sure you are not duplicating efforts.
The sonde with sensors was deployed manually from a raft or other floating craft (e.g. Caddis Fly inflatable seat). The sonde was lowered at one meter intervals and, at each depth interval, the reading was allowed to stabilize before readings were transcribed from the handheld meter to a dive slate in the field. Following return to the laboratory, data on the dive slate were entered into a spreadsheet, a preliminary plot made, and any apparent erroneous data (e.g. density inversions) were double-checked for accuracy of transcription and corrected as necessary.
BCO-DMO Processing: - added conventional header with dataset name, PI name, version date - renamed parameters to BCO-DMO standard - reformatted date from dd-Mon-yy to yyyy-mm-dd (ISO date format) - replaced blanks cells with nd - removed blank lines and unmatched quote ('); eg. isn't becomes 'is not'

Dissolved oxygen, temperature, pH, chlorophyll fluorescence and salinity/conductivity were measured using a HydroLab DS5 Multiparameter Data Sonde (Hach Company, Loveland, CO, USA).
Multi-parameter probes that can measure from 12 (MS5) to 16 (DS5 and DS5X) parameters simultaneously. Measurements include temperature, depth, conductivity, salinity, specific conductance, TDS, pH, ORP, dissolved oxygen, turbidity, chlorophyll a, blue-green algae, Rhodamine WT, ammonium, nitrate, chloride, PAR and total dissolved gases. These probes can be deployed at depths up to 200 m and can be used in continuous monitoring programs.
