Hi folks

We've been running CNS on our new Pyro Cube/visION machine and have been really impressed with the results.
The last batch of marine fish livers however include values >21 ‰, which (possibly reflecting my ignorance of all things d34S) I thought was the upper limit for marine-derived S.

Although I think it is likely teething problems with us and the machine, I wondered if anyone in IsoGeochem land has seen d34S values in fish etc higher than 21 ‰? We are in a rather odd location (Humboldt Current), with lots of upwelling/productivity so strange things do happen here biologically that often have big isotopic impacts and turn established norms on their head. 

Cheers
Chris
