Dear All, July 19, 2014
There is an article in today's Chronicle Herald about slow recovery of a
Salmon pen site in Shelburne Harbour.

I am wondering if the sulphide target they refer to (less than 1,5000
micromolar) is actually Hydrogen Sulphide. I would think; that a bottom
sludge of manure and food would quickly become anaerobic, unless moved
around/disturbed by ocean currents, and would quickly become the typical
dead zone in which fossils are best preserved.
Has aeration been tested in recovering or active sites ?
