Water Data for McAllister Creek at Site MC3

Two sensors, a vented conductivity, temperature and depth sensor (CTD) and a turbidity meter, were installed on a piling at the mouth of McAllister Creek at site MC3 (N 47o 06’ 01”/W 122o 43’ 36”) and connected to a telemetered data collection platform that was used to program, power, and log data for each sensor. Timing of the 15-minute sampling interval was synched among both sensors. The site is tidally influenced. The CTD (InSitu Aqua Troll) measured water temperature, water depth, specific conductance, and salinity from December 24, 2016 to February 17, 2017 (55 days). Water depth ranged from 0.52 to 5.49 meters. Temperature ranged from 1.1 to 9.8 degrees C. Specific conductance ranged from 5,500 to 43,100 uS/cm. Salinity ranged from 3.4 to 31.5 PSU. The turbidity meter (FTS DTS-12) measured turbidity and temperature from December 1, 2016 to March 31, 2017 (120 days). Turbidity ranged from 0.6 to 103.6 FNU. Temperature ranged from 1.3 to 13.1 degrees C. Data gaps of 15-minutes or more were reported as “NA” and occurred when either: the variance of turbidity measurements exceeded twice the measured value, or when the turbidity sensor was out of water.
