The analysis and recommended design of a high-resolution digital data acquisition system for the in situ measurement of various physical and chemical parameters of sea water

Creator:: Albin, Arthur Grayson
Abstract:: The lack of availability of a single, complete paper on the analysis of a digital data acquisition system for in situ oceanographic measurements brought about the present work. In order to compile an accurate technical paper on such a complex system, it was necessary to design, construct, and calibrate a...
