Temporal variations in phosphorus species [total phosphorus (Ptot), organic phosphorus (Porg), total inorganic phosphorus (Pmin), phosphorus bound to calcium (PCa), aluminium (PAl) and iron (PFe)] were studied in the surface layer of bottom sediments from the Gulf of Gda?sk. These changes were caused mainly by variability in Porg, PAl and PFe concentrations and were closely related to the growth cycle in the basin. The phosphorus concentration was higher in the spring and summer (April - September) that in the autumn and winter (November-March). For much of the year concentrations of Pmin were higher than those of organic phosphorus. The prevalent form of inorganic phosphorus was PCa, whose concentrations exceeded those of iron- and aluminium-bound phosphorus.
