30th Annual Plymouth Marine Science Lecture
  • Lecture Theatre 2, Roland Levinsky Building, Plymouth University

Save event

The Plymouth Marine Science and Education Foundation (PlyMSEF) is delighted to announce that this year’s Plymouth Marine Science Lecture will be given by invited guest speaker Professor Gideon Henderson.

Many metals are present in seawater at vanishing low concentrations, but these trace elements are nevertheless critical to the ocean system. Some, such as Fe, Mn, Co, and Zn, are required by biology, so govern the amount and type of life in the ocean. Some are toxic (Cd, Cu, Pb and Hg, for instance) so that human-induced change in their concentrations represents a future threat. And some are powerful tracers shedding light on modern ocean processes and on past climate change.

The last decade has seen a revolution in our understanding of the cycling of these trace metals, driven by co-ordinated measurements across the global ocean. This talk will introduce the scientific and logistical challenges of this advance, and highlight some of the key discoveries of recent years, particularly those from the GEOTRACES programme. Examples will include research in the South Atlantic to quantify the cycle of Fe, and the use of Cd isotopes to assess toxicity of that metal. 

The lecture will close with an overview of the changing nature of these metal cycles, and of the challenges facing scientists and the ocean environment.

This free lecture is open to all and doors will open from 5.30pm for a 6pm start.

Speaker biography

Professor Gideon Henderson FRS is a geochemist whose research focuses on the influence of marine chemistry on the carbon cycle and climate, and on understanding long-term climate change by study of the past. A particular expertise is the use of natural radioactive isotopes to establish the rates of oceanic processes, and the timing of past climate events. He seeks to understand components of the climate system with relevance to the future, including changes in rainfall, sea level, permafrost, and ocean circulation. He has played a leading role in establishing the international and UK GEOTRACES programmes, investigating the trace-element chemistry of the oceans.

Gideon is Head of the Earth Sciences Department at the University of Oxford. He has a degree in Earth Sciences from the University of Oxford, a PhD in Geochemistry from the University of Cambridge (UK), and previously worked at Columbia University (USA). He was elected a Fellow of the Royal Society in 2013.
