FIGURE 1.6 STATION LOCATIONS OF WAVES, CURRENTS, WATER QUALITY AND BIOLOGICAL PARAMETERS 14
1.3.3. Water quality Parameters Three perpendicular transects, off JMC were selected for sampling purpose. Each transect has three stations (as shown in Figure 1.6) within the depth range of 10 - 20 m and two stations in the creek (Figure 1.7) wherein water samples were collected for chemical analysis. A Niskin Water sampler has been used for collection of water samples from surface and near bottom depths. Water samples were collected in pre cleaned glass/plastic bottles. The water samples were fixed immediately for Dissolved Oxygen (DO) and for Biochemical Oxygen Demand (BOD). Samples for nutrient analysis were collected in plastic bottles and kept frozen until the samples reached shore laboratory. Analysis was carried out within the stipulated period of time in the shore laboratory. Brief accounts of methodology for estimation of chemical constituents are given below. 1.3.3.1 pH Water pH was measured immediately using Lab-India pH Analyser (PHAN) after standardizing it with standard pH buffers. 1.3.3.2 Dissolved Oxygen (DO) Winkler’s method was adopted for the determination of DO by fixing a measured volume of water sample immediately after collection with the reagents A (manganous chloride) and B (alkaline potassium iodide). Standard iodiometric titration with sodium thiosulphate was adopted for the analysis purpose. DO is expressed in mg/l. 1.3.3.3 Biochemical Oxygen Demand (BOD) Samples for the determination of Biochemical Oxygen Demand were collected in triplicate. The dissolved oxygen concentration was immediately determined using one of the triplicate samples according to Winkler Method. The remaining bottles were then left for five days at 20ºC in the BOD incubator. Dissolved oxygen in these samples was determined after fixing the samples on completion of five days incubation. BOD5 was computed from the initial DO concentrations and expressed in mg/l. 15
