The goal of this study was to assess the role of Cystoseira phytocenosis as a biochemical barrier to the phosphorus detrophication through the phytoplankton primary production in waters of the specially protected natural area (SPNA) “Cape Martyan” on the southern coast of Crimea. We present data on the mineral phosphorus concentration in seawater and in the brown algae Cystoseira (Cystoseira s.l.) phytocenosis in 2021 and the phytoplankton primary production in 2017 – 2019. In the SPNA sublittoral zone, wet weight of the Cystoseira phytocenosis was estimated at 1425.6 tons, the production 3136.3 tons year–1, and the phosphorus accumulation factor 20,900 – 54,500. The phosphorus pool in the Cystoseira biotope ranged from 69.6 to 78.99% of that in the sublittoral zone and decreased with the phosphate concentration increase. The primary production in the SPNA sublittoral zone was mainly phosphate-limited. With the phosphate concentration increase, the primary production can reach hypereutrophication levels (100 mg Corg m–3 day–1). The phosphorus accumulation in the Cystoseira biotope reduced the phosphorus availability for the primary production to 10.4 – 30.4%. By the example of the SPNA “Cape Martyan”, we show that Cystoseira phytocenosis is a highly efficient barrier to the phosphorus detrophication in coastal waters.

Information about the peculiarities of the formation of storm emissions of macrophyte on the coast, at cape Martyan (the Southern coast of the Crimea) is presented. The studies were conducted from June 2019 to August 2020. Storm emissions on this part of the coast are formed with winds from the eastern (including north-eastern and south - eastern), southern and south-western directions and the corresponding direction of the waves. With north and west winds, the accumulated algae are carried back to the sea. Along the leveled coastal areas, storm emissions are distributed fairly evenly, without forming abundant accumulations. Stable zones accumulation of emissions are formed near the block heap, as well as at the bases of hydraulic structures. During one storm, cast ashore 40 kg to 7784 kg of phytomass. In total, 33061 kg of storm emissions were received on the shore during the year, which is about one percent of the annual production and a little more than two percent of the bottom vegetation reserves of the adjacent water area. The volume of storm emissions depends on the intensity of wave activity, the direction and strength of winds, on the morphology of the coast, as well as on seasonal phenomena in the life cycle of macrophytes.
