Abstract
Seagrasses in coastal ecosystems play an important role in creating habitat diversity and transforming energy and matter. Their thickets form canopies in which a light gradient is created. The studies were conducted on August 14, 2019, in the shallow part of Kazachya Bay (Sevastopol, Black Sea) under cloudless sky conditions. At a selected point in the canopy of the Zostera noltii seagrass, measurements of the intensity of photosynthetically active radiation (PAR) were taken. During the entire study period, the plants were in a vertical state. It was found that the distribution of Z. noltii biomass by canopy height changed unevenly, increasing with depth, and this is reflected in the vertical distribution of PAR. It was noted that PAR decreases with canopy depth, and the nature of this decrease largely depends on the height of the sun.
