JGR-B will publish a special issue in 1985 focusing on the results obtained by 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 is encouraged. Special reduced rates for color will apply. Papers describing results obtained by using these new 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. Submission deadline is September 30, 1984. Publication is planned for July or August 1985.
