Please join us for BGS this week, with speaker Norm Nelson. He'll give us a talk entitled, "Chromophoric dissolved organic matter and refractory carbon storage in the deep sea".

 
Description:
'The deep ocean holds vast amounts of organic carbon (up to 700 Pg C), much of it in chemical forms that are resistant to microbial degradation. But the dissolved organic matter pool is poorly characterized because of the large numbers of compounds and the difficulty of identifying even a small fraction of them. However, certain optical properties of the DOM, spectral absorption and fluorescence, correlate well with diagenesis of refractory DOM in the ocean. I’ll speak briefly on the prospects for using spectroscopic tools to characterize DOM in the context of understanding the source and lifetime of the refractory carbon in the deep ocean.'
 
As always, BGS is at noon in the 6th floor conference room of Ellison (6824), and there will be light snacks and beverages provided.  Please feel free to bring your lunch.
