The Journal of Geophysical Research, B, will publish a special issue in 1985 focusing on the results obtained using a variety of new seafloor mapping tools (e.g., SEA BEAM, SEA MARC I and II, GLORIA, GEOS-3 and Seasat radar altimetry). Liberal use of color and large-format black and white figures are encouraged. Special reduced rates for color will apply. The submission deadline is September 1, 1984; publication is planned for July or August 1985.

Papers describing results obtained using these new mapping techniques in a variety of tectonic environments (e.g., mid-ocean ridges, active margins, passive margins, seamounts) are solicited as well as papers describing instrumentation and data processing and interpretation techniques.
