Is there any way to derive information on past light levels in peats (cohorts)?

26 February 2014 0 2K Report

Past light levels could be derived by using optically stimulated luminescence (OSL) on sand, but that is not really present in peats; however, testate amoebae or other silica based organic materials might be?

Otherwise, maybe UV sensitive compounds could be used (indicating past light level stress).

Anything else I might want to consider?
