Technical ReportCHART : a computer plotting package for the display of position-dependent marine data(Woods Hole Oceanographic Institution, 1986-12) Martin, AnnComputer program CHART produces plots of navigation tracks and data points in a choice of 14 projections where navigation coordinates are defined. It was written specifically for the plotting and annotation of geological and geophysical data; however, any data which includes geographical coordinates can be plotted. The package was designed for broad flexibility of applications and for ease of use. Parameters are entered interactively; the user responds to online prompts worded in plain English. Several levels of default choices are incorporated; a user who takes all defaults can produce a plot by entering only the data source and format, and plot bounds . CHART can be used on any Digital Equipment Corporation VAX machine running VMS. It uses plotting subroutines
Technical ReportVOICE - a spectrogram computer display package(Woods Hole Oceanographic Institution, 1990-07) Martin, Ann ; Catipovic, Josko A. ; Fristrup, Kurt M. ; Tyack, Peter L.A real-time spetrogram instrument has been developed to provide an inexpensive and field-portable instrument for the analysis of animal sounds. The instrument integrates a computer graphics display package with a PC-AT computer equipped with an A/D board and a digital signal processing board. It provides a real-time spectrogram display of frequencies up to 50kHz in a variety of modes: a running display, a signal halted on screen, successive expanded views of the signal. The signal amplitude may also be displayed. Portions of the scrolled data may be saved to disk file for future viewing, or as part of a database collection. The screen display may be manipulated to adapt to special needs. Program source listings are included in the text.
Technical ReportAdvanced Engineering Laboratory project summaries 1989(Woods Hole Oceanographic Institution, 1990-05) Frye, Daniel E. ; Stone, Ellen ; Martin, AnnThe Advanced Engineering Laboratory of the Woods Hole Oceanographic Institution is a development laboratory within the Applied Ocean Physics and Engineering Department. Its function is the development of oceanographic instrumentation to test developing theories in ocean physics, and to enhance current research projects in other disciplines within the oceanographic community. This report summarizes recent and ongoing projects performed by members of the laboratory.
