title: Nutrients Dynamics in the Surface Waters of the Black Sea
abstract: Purpose. One of the key characteristics of water quality and marine ecosystems' sustainability is nutrients supply, which are the main factors of phytoplankton bloom. Since the mid-20 th century, in the northwestern Black Sea and on its western shelf significant changes in nutrients concentrations took place, which were manifested in increase of the inorganic nitrogen and phosphorus concentrations and decrease of the dissolved silicon content, that in its turn, led to a strong anthropogenic eutr
