This project addresses the sensors and recording system                 necessary to make long term in situ measurements of water                       properties.  The main problem in obtaining the required                         accuracy (about 0.01 ppt for salinity) is the stability of                      conductivity measurements.  The principal investigator has been                 working with moored conductivity measurements for the past 15                   years and has used both electrode and inductive sensors.  In                    the deep ocean, very small drifts have been observed over                       several months, but in shallow waters, drifts of as large as                    0.1 ppt in salinity have occurred in a few months.  Four tasks                  will be carried out:  (1) conductivity sensor performance in                    various configurations and locations will be summarized, (ii)                   spatial and temporal aliasing errors will be investigated,                      (iii) sampling and digitizing accuracy will be estimated, and                   (iv) a power budget and memory size will be derived.
