Published by Germany's Imperial Naval Observatory as a companion to the Segelhandbuch für den Indischen Ozean, this atlas contains 35 color lithographic charts printed by Wagner & Debes of Leipzig — covering ocean depths, currents, sea temperatures, barometric pressure, wind patterns, shipping lanes, and whale distribution across the Indian Ocean. The Deutsche Seewarte ocean atlases are the high-water mark of 19th-century oceanographic cartography, and the Indian Ocean volume is the scarcest of the three (Atlantic, Indian, and Pacific). Preceded by a detailed explanatory text citing survey data from named vessels including HMS Challenger and SMS Gazelle. Rarely seen on the market.
