Andrew Bramburger

The 14C uptake method is still the most reliable indicator of C assimilation but can be expensive. Using light/dark BOD bottles and a DO meter to look at oxygen evolution is probably the next best approach and doesn't require expensive reagents. I would recommend against using Chl- based estimations unless you only need a really approximate estimation or are interested in relative PP rates.

Dear Dr Arvind Singh and Dr. Andrew Bramburger
