Abstract

The Hawaii Ocean Time-series (HOT) data base presently incorporates a suite of 35 different measurements covering the water column from 0 to 5000 m at the different HOT study sites. Data have been collected from 53 cruises since October 1988 and each cruise has about 20 CTD-rosette casts consisting of separate sensor and bottle data. In addition to these data, the HOT data base includes time-series measurements of biogeochemical rates such as primary production and particle flux. The HOT-Joint Global Ocean Flux Study (JGOFS) program has developed a computerized system of data compilation, quality assurance and quality control, historical file management and graphical presentation of the various sets of data. This system is UNIX-based and requires MATLAB 4.1 for best results. The present application allows two dimensional graphing of any parameter within a cruise, between cruises and between stations. Further graphical presentations include historical plotting, time series analysis contouring and a time-step presentation showing temporal changes of pressure/density distribution of any parameter. The computerized system is user-friendly and operates in a windows-like environment. It is extremely flexible and allows for expansion and interfacing with other data sets.
