The data was recorded to two-way travel-times of 15 to 23 seconds, with 50-75 m shot spacing. Two north-south transects were profiled. The eastern transect extended from 58 degrees 50'N, 168 degrees 32'W, well within the continental shelf of the Bering Sea, north of the Pribilof Islands, to just south of the shelf edge north of Barrow, Alaska, at 71 degrees 49'N, 154 degrees 33'W. Ice prevented continuation of the line beyond the shelf edge. The western transect extended from the central Chukchi Sea, well within the shelf at 71 degrees 23'N, 163 degrees 00'W, into the Aleutian basin at 58 degrees 00'N, 178 degrees 30'W, near Navarinsky Canyon. An additional short line crossing over the Beringian margin a second time was recorded near Zemchung Canyon east of the western transect. The profiles cross important strike-slip faults, possible terrane boundaries, two continental margins, and several Cretaceous/Tertiary sedimentary basins (Norton, Hope, Chukchi, and Navarin Basins). Together with the preceding cruise EW9409, the profiles provide a continuous transect across the North American continent, from the Pacific to Arctic Ocean. Most of the multi-channel (MCS) data is of high quality, but bad weather, strong currents, and recording problems sometimes presented difficulties during data acquisition. Gravity, magnetic, and sonobuoy data were also recorded along the profiles.
