Slimewatch – summer 2019

Back to my roots as a biologist in this art/science project within University of Westminster.
Summer 2019 will be busy, collaborating with Professor Jane Lewis and biochemistry student Dain Son
– and planning for exhibition at the Regent St. Café Gallery this September.








The Thames in central London is turbid; plankton in the water column don’t get much light for photosynthesis. But inter-tidal mudflats offer opportunities to their relations, the surface-dwelling benthos.
When the tide falls and daylight reaches the foreshore, ‘commuter diatoms’ and other micro-algae migrate vertically up through the grey mud. As individuals, they are microscopically small. As communities, they bloom into visible coloured patches of reds, browns and greens – chlorophyll, accessorised with other pigments.
They use these pigments to photosynthesise and fix atmospheric carbon
into arrays of organic molecules – the basis of whole ecosytems.
And they use some of this energy themselves, to migrate back down when the tide rises.

More on this, and ongoing work with Crispin Hughes, here at the Thames Tides website:
