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,

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. There is a funded program, the Hawaii-2 Observatory ...
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. ...
Challenges to understanding the dynamic response of Greenland's marine terminating glaciers to oceanic and atmospheric forcing Straneo, Fiamma; Heimbach, Patrick; Sergienko, Olga; Hamilton, Gordon S.; Catania, Ginny; Griffies, Stephen; Hallberg, Robert; Jenkins, Adrian; Joughin, Ian; Motyka, Roman; Pfeffer, W. Tad; Price, Stephen F.; Rignot, Eric; Scambos, Ted; Truffer, Martin; Vieli, Andreas (American Meteorological Society, 2013-08)The recent retreat and speedup of outlet glaciers, as well as enhanced surface melting around the ice sheet margin, have increased Greenland's contribution to sea level rise to 0.6 ± 0.1 mm yr−1 and its discharge of ...
