Description:
The instrument used to obtain the extracted chlorophyll a and pheophytin values. All LTPTS samples and samples from May 2018 through July 2018 were read on a 10AU fluorometer (Turner Designs; Inc.; San Jose; CA; USA); while samples from August 2018 through October 2019 were read on a Trilogy fluorometer (Turner Designs; Inc.; San Jose; CA; USA). Fluorometers were calibrated with commercially purchased chlorophyll a standards in 90% acetone solution (P/N: 10-850; Turner Designs; Inc.; San Jose; CA; USA).
