What is it about?
Seagrass meadows and other submerged vegetation play crucial roles in providing ecological services, but the extent of these services is not fully understood. Accurate estimations of primary productivity are essential in assessing and modeling these services, which require an understanding of the underwater light field. Here we developed a new and practical approach to estimate leaf light exposure in seagrass meadows and found that light reaching the leaves decreased linearly through the canopy. The study suggests using a correction factor (for light meter readings at the canopy) of 0.5 for vegetation similar to Z. marina when estimating light interception in submerged vegetation.
