Oceanographers now measure salinity with a salinometer which measures the electrical conductivity of the water. Salinity is now defined by the ratio of this measurement to the conductivity of a standard sample with a known salinity at the same temperature. When oceanographers collect conductivity vs. depth data by lowering a salinometer on a wire: Question 10 options: they are collecting scientific data. they are collecting data, but not scientific data. they get very different answers if they lower the salinometer in the same place many times on the same day. they are wasting their time
