Hello,

I have a question regarding measuring natural illuminant spectra underwater. I see that in the sample data file there is a csv for “5m green water 400-700 nm”. Could you share the technique of how this was measured? I’m interested in doing something similar but would like to know if the illuminant spectra should be measured in the same viewing plane as the animal or if measuring downwelling irradiance is ok.

Many thanks!

Mark
