Researchmethods - researchworkwascarriedoutonthebasisofhydrophysical, hydrochemicalandbiologicalobservationsmadeonthe north-westernshelfoftheBlackSeain 2017 and a historicalarrayofobservationaldata (2000-2017). ThedataofthepermanentcoastalmonitoringofUkrSECMintheOdessaregion, aswellassatellitedataonthechlorophyllcontentonthesurfaceoftheBlackandAzovSeas, andhydrometeorologicaldataattheportofOdessaportwereused. Resultsofthestudy - IntheOdessaregion, thereis a tendencytodecreasethecontentofmineralformsofnitrogen, anincreaseinthephosphorusphosphorusandtotalphosphoruswasobserved. Accordingtotheobservedincreaseintrophicityofwaterrelativetolastyear. Accordingtothecomplexindexofthe TRIX index, thewatersoftheOdessaregionin 2017 metthe "high" leveloftrophicity.
