Professor Henry "Harry" Elderfield, FRS, (born 1943), is Professor of Ocean Geochemistry and Palaeoclimate Research at the Godwin Laboratory, Department of Earth Sciences, Cambridge University. He made his name in ocean chemistry and palaeochemistry, using trace metals and isotopes in biogenic carbonate as palaeochemical tracers, and studying the chemistry of modern and ancient oceans - especially those of the glacial epoch and the Cenozoic.

Education and Career

Harry Elderfield attended the University of Liverpool obtaining a BSc in Chemistry (Oceanography) in 1965. He worked as a Research Fellow in the Geology Department, Imperial College, London between 1968-1969 whilst completing his PhD at the University of Liverpool in 1970. He was appointed a Lecturer in the Department of Earth Sciences, University of Leeds in 1969, a position he held until 1982. From 1982 until 1989 he held the post of Assistant Director in Research in the Department of Earth Sciences, Cambridge University. During this time he obtained an MA from the University of Cambridge in 1985, followed by his ScD in 1989. The same year, he was made a Reader in Geochemistry at Cambridge, before being appointed to the chair of Professor of Ocean Geochemistry and Paleochemistry (Cambridge) in 1999.

Early career

His early career saw him working on the behaviour of trace metals in oceans and their sediments, and in fluid flow through the ocean crust and sediments under the influence of off-axis hydrothermal circulation. He became one of the first low-temperature geochemists to appreciate how radiogenic isotopes might be used to solve the problems of marine geochemistry, developing the seawater strontium isotope curve for the Cenozoic [ Palmer, M.R. & Elderfield, H. (1985) Sr isotope composition of sea water over the past 75 Myr. Nature 314, 526-528] – now the most reliable isotopic record available for the Phanerozoic.

He has also worked on iodine speciation in seawater and porewaters, [ Wakefield, S.J. & Elderfield, H. (1985) Interstitial water iodine enrichments in sediments from the eastern Pacific. Journal of Marine Research 43, 951-961] the separation of cerium from other rare earth elements in a classic example of redox behaviour; [ German, C. R. & Elderfield, H. (1990) Application of the Ce-anomaly as a palaeoredox indicator: the ground rules. Paleoceanography 5, 823-833] he has developed a precise mass spectrometric analysis method – and made the first ever measurements of oceanic profiles for – 10 rare earth elements. The rare earths are now widely used as tracers in sedimentary geochemistry and palaeoceanography.

Current Research

Harry Elderfield's research focuses on ocean chemistry and paleochemistry, and his results have had a far-reaching impact on geochemistry. He has contributed significantly to marine chemistry, most notably the fate of metals in hydrothermal processes, the formation of manganese nodules [Elderfield H, Hawkesworth CJ, Greaves MJ, et al. (1981) Rare-earth element geochemistry of oceanic ferromanganese nodules and associated sediments. Geochim. Cosmochim. Acta 45: 513-528] , and the biogeochemical cycles of elements including iodine and strontium.

His current interests include defining chemical proxies from biogenic carbonates and using them to understand the ancient ocean. He has pioneered the development of foraminiferal magnesium thermometry, which has become accepted for the estimation of past ocean temperatures.
