Overview

Perform CTD observations using the memory CTD Rinko-profiler (ASTD102-ALC-R02). Depth [m], water temperature [Celsius], salinity, conductivity [mS / cm], EC25 [microS / cm], Density [kg /m^3], sigmaT, Chl-Flu. [ppb], Chl-a [ microg /l], medium turbidity range [FTU], DO [%], DO [mg / l], and battery voltage [V] Acquire profile data including. The date and time of the survey, latitude, longitude, and water depth at each observation point are described in a dedicated CSV file.(TimeLatLonDep_2014AprOtsuchiCTD_Tanaka.csv)
