The “Johannes Schmidt” Ridge in the Indian Ocean


IN his second report on “The John Murray Expedition to the Arabian Sea” (NATURE, May 5, p. 669), Lieut.-Col. Seymour Sewell announces that the echo soundings made from H.E.M.S. Mabahiss prove the existence of a vast submarine ridge running diagonally across the north Indian Ocean from the south-east to the north-west and connecting the Chagos Archipelago with Socotra and the Gulf of Aden. May I suggest that the name of Denmark's great oceanographer, the late Dr. Johannes Schmidt, whose discovery of this submarine formation Col. Sewell graciously acknowledges, shall be given to it?
