Eric, Here's an article about the monitoring of the THC: http://www.nerc.ac.uk/publications/planetearth/2008/summer/sum08-rapid.pdf from the UK government organisation NERC. They produce a magazine which reports some of their work each quarter, which can be found here. http://www.nerc.ac.uk/publications/planetearth/
The articles can be interesting and not too heavy :-) Cheers, Alastair.
