The scent of the sea - Ode to Emiliania
Prof. dr. Jos van den Broek (Leiden University)
The scent of the sea - Ode to Emiliania is an interactive visual
lecture in which the origin of the odour of the sea is revealed. This lecture is
initiated by Satellietgroep and The NIP in the context of the project 'Now Wakes
The Sea'. One of the most important organisms on Earth is Emiliania
huxleyi due to its presumed role in the Gaia concept of a self-regulating
Mother Earth. It is one of thousands of different photosynthetic plankton that
freely drift in the ocean, forming the basis of virtually all marine food
webs. E. huxleyi is by far the most abundant coccolithophore found in
the Earth's oceans, and is considered ubiquitous, occurring everywhere except
the polar regions. E. huxleyi has the potential to act as a net source
of CO2 out of the ocean as a reaction to ocean acidification. Its
sulphur-containing products are responsible for the typical sea odour.
Jos van den Broek graduated as a biochemist at Leiden University, where
he also got his Ph.D. degree in pharmacology. From 1981 he is professionally
involved in science communication. From 1989-1990 he earned a Knight Science
Journalism Fellowship at the Massachusetts Institute of Technology (MIT). At the
end of 2003 he rejoined Leiden University in order to set up the Science &
Communication Ma specialization at the Faculty of Science. He now is Professor
in Biomedical Science Communication at the Faculty of Science of Leiden
University, focusing on health awareness, nature awareness and universe
awareness. Visual communication for the illiterate is one of his main interests
in science and health communication. He is co-author and designer of the visual
communication handbook Beeldtaal (Spring 2010), published in English as Visual
Language in 2012. He wrote and co-authored numerous popular-science books on
science experiments, nature, evolution and ageing. In his most recent book he
answers questions of children on biological issues. He is now at the brink of
publishing a similar book on questions about Eart, Sun and astronomy. Playful is
his middle name.
