The significance of graphic communications has been a factor of man's existence throughout history. Although differences of language inhibit communication, the properly presented graphic allows people of different nationalities, different social levels and different professions to communicate their ideas. It is the technique of graphic presentation that has been changing and in recent years the variety of techniques available have increased enormously. There has been a significant increase in the use of colour during this century and in recent years the kaleidoscope of fluorescent colours. Oceanographic instrumentation has been completely metamorphized during the last two decades. Mechanical devices have given way to electronic systems. There is extensive use of computers both ashore and afloat and many instruments are directly coupled to computers. The use of acoustics has been extended from the field of anti-submarine warfare and simple echo sounding to a wide variety of acoustic sensing and measuring devices of which side scan sonar is the best known. Much of the data is manipulated in mathematical form and there is extensive use of mathematical modelling. Yet, for some purposes, the graphic portrayal of oceanographic data is for conceptualizing processes, for communication with colleagues in the form of scientific papers and their illustrations and for describing oceanographic features and processes to the public at large. There appears to be a hiatus between the use of conventional graphic techniques and the output from new kinds of oceanographic instrumentation. How can a satellite image be most effectively translated into a hard copy graphic? How can the differing signal strength from an acoustic system be shown in a way that is meaningful to the geologist? These are but some of the cartographic problems that must be resolved and the working meeting that is reported upon through the pages of this book is but one step in this pursuit.
