Optical classifiion and characterization of marine

Water samples were filtered onto precousted 25 mm GF/F filters; sample filters were then transferred to clean glass scintillation vials,dried at 60°C,and stored until post cruise analysis. Following acidifiion to remove inorganic carbon,a standard high temperature coustion technique was used to determine POC on each filter.

Collecting and Processing Stream Water Samples

Samples collected for chorophenoxy-acid herbicides and carbamates (NWQL schedules 2050 and 2051) use the high-pressure liquid-chromatography (HPLC) method. These synthetic-organic compounds in stream water interact with sediment particles through sorptive processes; therefore,it is important to separate the solid phase from the sample as soon
