Meteorological packages; discrete water samplers; titrators


Years: 1961-1997 Months: seasonal surveys (February, May, August, October) Location: Standard net of stations in the Central Baltic (16 stations) and standard net of stations in the economical zone of Latvia since 1992 Depth: On all the stations north from 56o10' (Latvia- Lithuania border) all the parameters are determined from the surface till the bottom after each 10 m, on all the stations south from 56o10' all the parameters are determined from the surface till the bottom after each 5 m. Data processing: Till 1992 the salinity was determined with Knudsen method by titrating for Cl, since 1992 - by inductive salinometer (model 601-MIII, YEO-KAL, Australia). Oxygen concentration is determined by Vincler method; till 1993 - titration with burette, since 1994 - by Titration Stand for Oxygen (Dosimat 715, Hydro-Bios).
