Robert (Bob) Dickson (1941-), oceanographer, has made important contributions to our understanding of currents and circulation of the Atlantic and Arctic Oceans. Since 1964, he has worked in the Ministry of Agriculture, Fisheries and Food’s fisheries laboratory, in Lowestoft, Suffolk (now the Centre for Environment, Fisheries, and Aquaculture Science – Cefas). An early focus on relations between ocean conditions andfish stocks, followed by commissions to measure the flow of ocean currents in order to plan for nuclear waste disposal at sea, led to a more recent focus on the role of ocean circulation (especially the Arctic-Subarctic ‘flux’) in global climate change. Bob was the oceanographer who first identified, in the late 1960s/early 1970s, the ‘Great Salinity Anomaly’ – a pulse of freshwater to the Nordic Seas. Outside of work, Bob has written a children’s book and children’s plays performed at Pleasurewood Hills Theme Park and collects antiquarian books.
