Can anyone give the specifications (material, dia, structure ) of a benthic chamber required for measuring seagrass productivity by using O2 probes?

10 January 2014 1 2K Report

The size, volume, material etc. of the benthic chamber are important.

Typically for benthic chambers you should use a clear material, if you have lots of $$$ you can go with acrylic but the cheaper alternative is plexiglass. For the most part the diameter doesn't really matter since you should be factoring this into the flux/productivity calculations, however you don't want to go too small. Below are two links to paper discussing benthic chambers. Hope this helps.
