Giancarlo Costa comes from a family with a strong shipping and navigation background, so it is not a surprise that he has travelled extensively across the planet's oceans and seas, using almost every type of equipment available to a sailor, journeying from Polynesia to Greenland, the USA, North and East Africa, as well as the Middle and Far East. Since 1965, Costa has been registered with the Register of Journalists in Italy, and in that same year he settled in Milan, where he continues to collaborate with trade magazines, specialising in iconographic research on behalf of newspapers and publishing houses. His photographic archive comprises over 100,000 images. Giancarlo Costa is also a diving consultant at the Museum of Science and Technology in Milan. He collaborates with the Maritime Museum of Cesenatico and with the Galata Museo del Mare of Genoa on their exhibitions and publications. He lives in Milan with his wife Barbara and their cat Oberon.
