Dissolved organic matter in freshwaters: nature, origins and ecological significance

Scientific meeting

Location

Kavli Royal Society Centre, Chicheley Hall, Newport Pagnell, Buckinghamshire, MK16 9JJ

Overview

Theo Murphy international scientific meeting organised by Professor Penny Johnes, Professor Davey Jones, Professor Stephen Maberly and Professor Richard Evershed FRS.

DOM in freshwater

Dissolved organic matter (DOM) plays an important role in ecosystem function. Its flux to waters is rising globally, driven by population growth, agricultural intensification, land use and climate change. This meeting brings together a cross-disciplinary community to debate and discuss current understanding of the nature, origins and ecological significance of DOM in freshwaters, and identify exciting opportunities for future research.

The schedule of talks and speaker biographies will be available soon. Speaker abstracts will be available closer to the meeting date. Recorded audio of the presentations will be available on this page after the meeting has taken place.

Poster session

There will be a poster session at 17.30 on Monday 20 January 2020. If you would like to apply to present a poster please submit your proposed title, abstract (not more than 200 words and in third person), author list, name of the proposed presenter and institution to the Scientific Programmes team no later than 15 November 2019. Please note that places are limited and posters are selected at the scientific organisers' discretion. Poster abstracts will only be considered if the presenter is registered to attend the meeting.
