These data were acquired in 1998 and 1999 with the Research Vessels Tommy Munro (M1-98-GM) and Gyre (G1-99-GM).  The data are available in binary and GIF image formats.  Binary data are in Society of Exploration Geologists (SEG) SEG-Y format and may be downloaded for further processing or display.  Reference maps and GIF images of the profiles may be viewed with your Web browser.",
