Why is important to measure … Web1 apr. 2011 · In water legs, salinity can be determined directly using two techniques; produced water samples, or by centrifuging free water out of conventional core cut with oil-based mud. Aquifer water resistivity can also be indirectly estimated using Picket plots.
WebTo determine isohalines, scientists measure the water's salinity at various depths in different parts of the estuary. They record these salinity measurements as individual data points. Contour lines are drawn connecting data points that have the same salinity measurements. WebStep 6: Calibrating. Since the measured resistivity could not immediately give the salinity level of the water, it is required to calibrate the sensor. The very first important step in …
