Jolyn de Zwart did some modeling of the effect of diurnal cycles on DMS
release and the parameters affecting this in algal mats. I don't have the
references to hand, but a search on her name, combined with our Prof -
J.Gijs Kuenen, should turn them up. Other wise contact me and I'll see what
I can do. There was also a lovely piece of work done back in the '80s, I
think, by Bo Jorgenson (that first o should have a slash through it) and
others on the effect of light/dark cycles on communities of
sulphur-oxidizers, some of which moved up and down with the sulphide
boundary. I think it was published in the Proceedings of the Royal Society
of London - he's at the Max Planck Institute in Bremen if you need to ask
for a reprint.
