Underwater Measurements and Immersion Effect
Sager, J.C., W.O. Smith, J.L. Edwards, and K.L. Cyr, 1988. Photosynthetic efficiency and phytochrome photoequilibria
When a quantum sensor that was calibrated in air is used to make underwater measurements, the sensor reads
determination using spectral data. Transactions of the ASAE 31:1882-1889.
Correlation between
photosynthetic photon flux
density (PPFD) and yield photon
flux density (YPFD) for multiple
different radiation sources. YPFD
is approximately 90 % of PPFD.
Measurements were made with
a spectroradiometer (Apogee
Instruments model PS-200) and
weighting factors shown in the
previous figure were used to
calculate PPFD and YPFD.
