Nils Bang

Nils Bang died, aged 36, of colon cancer, in Durban's Entabeni Hospital on 2 December 1977. At dawn on 27 January 1978, members of the CSIR staff along with his friend, retired Port Captain Jimmy Deacon, aboard the research ship Meiring Naude, committed his ashes to the sea between Umkomaas and Scottburgh on the Natal south coast.

Conducted along the length of the current, south of latitude 27°S, this 18-day project, from 6 to 24 March 1969, included three ships: the University of Cape Town's research vessel Thomas B. Davie, the CSIR's Meiring Naude, and the Department of Sea Fisheries' Africana II. Most of data gathered was obtained from systematically calibrated surface thermograph records from the ships: Thomas B. Davie operated from west to east working the segment between Mossel Bay and the Great Fish River (as far as 500 miles south), while Meiring Naude and Africana II worked simultaneously from east to west, the former covering the Kosi Bay to East London segment and the latter the Mossel Bay to St Helena Bay segment. A CSIR aircraft—equipped with an infrared radiation thermometer for measuring ocean temperatures from a height of 1,000 feet—flew traverses across the current from Cape St Lucia to Cape Town. Some 10,000 sea water samples were taken and a similar number of temperature readings. An uncharted 9,500-foot seamount found in the course of the cruise was named the Davie Seamount.

Nils Bang's oceanographic research began in 1965 when he joined the Naval Oceanographic Research unit in Youngsfield, near Cape Town. He then moved to the Oceanographic Institute at the University of Cape Town, where his key research was accomplished. In June 1965, he was selected as South Africa's representative on board the US research ship, Atlantis II, the flagship of Woods Hole Oceanographic Institution, to take part in the multi-ship International Indian Ocean Expedition, which he accompanied on a traverse of the continental shelf from Maputo to Durban—researching the evolution and significance of submarine canyons—and then on to Australia, visiting oceanographic institutions there. After post-doctoral studies at the Geophysical Institute, University of Bergen, Norway, he joined the newly formed National Research Institute of Oceanography of the Council for Scientific and Industrial Research, Durban, where he remained until his death.

He married Mary Alison Coombe, a midwife, on 21 August 1965, in Pietermaritzburg. He credited his inspiration for the "retroflection" metaphor to his wife who had taught him the term during her midwifery studies. In 1967, their first daughter, Kirsten, was born in Cape Town, followed by two more daughters, Solveig in 1970 and Janice in 1973.

Nils Daniel Bang (13 September 1941 – 2 December 1977) was a South African oceanographic scientist who was a pioneer in the study of the fine structure of coastal upwelling systems. In March 1969, Bang initiated, planned and executed South Africa's first truly multi-ship oceanographical research operation, the Agulhas Current Project, along the current's length. Although the research was conducted on a limited budget and with rudimentary equipment, Bang's studies using thousands of closely spaced bathythermograph readings were later corroborated by satellite imagery and airborne radiation thermometry.

Nils Bang was born in Durban, South Africa, on 13 September 1941. His father was Daniel Nielson Bang, a Zulu linguist and son of Norwegian missionaries, and his mother was Anna Maria Bang (née Linde), the daughter of Swedish missionaries. He had a younger sister and brother, Anaida and Knut Olav. He attended Merchiston Preparatory School and later Harward, both in Pietermaritzburg. During his school years, he was a sea cadet and attended a Commonwealth sea cadet course in Britain. He studied first at the University of Natal and then at the University of Cape Town where he was awarded a PhD in 1974.
