Please pass the saline

The principal developers of the salinometer —Karl Schleicher, right, and Alvin Bradshaw— are at work with their first model, in the mid-1950s, in the main lab of the research vessel Bear. Their Salinometer was based on an instrument developed by the Coast Guard for ice patrol work. It replaced silver nitrate titration, eliminated problems of using glassware at sea, improved the accuracy of salinity measurements, and doubled the number of analyses that could be handled in an hour.
