The first borehole seismic experiments on DSDP and ODP were two-ship Oblique Seismic Experiments (Stephen, 1979; Stephen, et al., 1979, 1980; Swift, et al., 1988). By recording on the drill ship and shooting explosives out to ranges of 8 km, the upper 1.5 km of the upper crust (Layer 2) adjacent to the borehole could be imaged (Fig. 1; Stephen and Harding, 1983), Azimuthal anisotropy (Stephen, 1981, 1985) and lateral heterogeneity (Stephen, 1988; Swift and Stephen, 1989) could also be studied by shooting circles of shots at a fixed range from the borehole,

Climate variability, oceanography, bowhead whale distribution, and Iñupiat subsistence whaling near Barrow, Alaska Ashjian, Carin J.; Braund, Stephen R.; Campbell, Robert G.; George, John C.; Kruse, Jack; Maslowski, Wieslaw; Moore, Sue E.; Nicolson, Craig R.; Okkonen, Stephen R.; Sherr, Barry F.; Sherr, Evelyn B.; Spitz, Yvette H. (Arctic Institute of North America, 2010-06)The annual migration of bowhead whales (Balaena mysticetus) past Barrow, Alaska, has provided subsistence hunting to Iñupiat for centuries. Bowheads recurrently feed on aggregations of zooplankton prey near Barrow in autumn. ...
Bathymetry and sediment thickness survey of the Hawaii-2 cable : cruise report for Kiwi expedition leg 2 on the R/V Roger Revelle Stephen, Ralph A.; Swift, Stephen A.; Greaves, Robert J. (Woods Hole Oceanographic Institution, 1997)The primary purpose of this cruise was to identify at least two potential observatory sites along the Hawaii-2 cable that would be suitable for drilling a hole to basement.
