Dennison Reef (66°29′S 66°50′W / 66.483°S 66.833°W) is a reef between Shull Rocks and Pauling Islands, lying east of the south end of the Biscoe Islands in Crystal Sound. Mapped from air photos obtained by the Ronne Antarctic Research Expedition (RARE) (1947–48) and surveys by Falkland Islands Dependencies Survey (FIDS) (1958–59). Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for David M. Dennison, British physicist who took x-ray diffraction pictures which were used to interpret the crystal structure of ice.
