CTD calibration and processing methods used at Woods Hole Oceanographic Institution

Abstract

Processing methods, programs, and procedures currently used to create CTD data sets at Woods Hole Oceanographic Institution (WHOI) are described. The post-acquisition data processing steps include instrument calibrations in the laboratory and data calibration at sea, CTD data transformation from a time series to a pressure series, and the water sample data processing using the World Ocean Circulation Experiment (WOCE) format guidelines. Processing software has been developed for both the Micro VAX and IBM compatible personal computers. The description of the data processing procedures is restricted to the PC system. The programs are written primarly in FORTRAN with some format-related changes required between computer systems.
