About the lab

Employees (Scientists) of the laboratory conduct basic scientific and applied research in chemical oceanography and sedimentology.
Our research includes:

  • monitoring the state of chemical parameters in seawater, sediment and organisms (algae, bivalves, fish)
  • laboratory and field investigations of processes that affect the biogeochemical behavior of various chemical elements and compounds in the sea
  • development and application of new, high-specific methods for determining nutrient inorganic salts, trace elements and organic compounds in the marine environment
  • determination of the presence of pollutants in the marine environment and their harmful effects on organisms

Field research is carried out in the marine environment of different trophic status (estuaries, estuaries, bays, open sea, farms of marine organisms) with the aim of detecting changes occurring under the influence of anthropogenic or climatic factors.

Seawater samples determine the pH value, dissolved oxygen content, concentrations of dissolved inorganic forms of nutrient salts (nitrates, nitrites, ammonia, orthophosphate, silicates) as well as organic phosphorus and nitrogen, organic pollutants and trace elements.

The sediment explores the redox potential, granulometric composition of sediments, the content of carbonates, organic matter, organic carbon, total nitrogen, speciation of phosphorus forms and organic pollutants and trace elements.

In marine organisms, organic pollutants and trace elements are determined.

The laboratory is equipped with a number of devices: photoelectric colorimeter (AA500 Seal Analytical), spectrophotometer (Shimadzu UV Mini 1240), atomic absorption spectrometer (Perkin Elmer Pinnacle 900 T), direct mercury analyser (Milestone DMA-80), gas chromatograph GC (Agilent 6890), microwave sample sample device (Speedwave 4, Berghof), pehametri (Mettler Toledo, Sartorius), deionizer (Purelab flex, ELGA), cryogenic mill (6875 Freezer/Mill, Spex Sample Prep), analytical balances (Mettler-Toledo), laboratory dryers, laboratory dryers, laboratory devices, annealing furnaces and seawater and sediment samplers on the IB “Bios DVA”.

Computer programs

Broj Kaveza (HR)

Program služi za izračun broja (kružnih) kaveza potrebnih za uzgoj zadane godišnje količine proizvodnje ribe. Pored veličine kaveza, zadaje se duljina uzgojnog ciklusa (do dvije ili tri godine), način korištenja kaveza.

SettlingVel (HR)

Program za izračunavanje brzine taloženja čestica. Pored sfernog oblika čestice može se birati još devet geometrijskih tijela koja su unutar odgovarajućeg Reynoldsovog broja. Dimenzije čestica mogu se generirati slučajnim brojevima iz zadanih razdioba (Uniform, Normal, Log-Normal, Exponential, Weibull, Empirical). Generirani podaci mogu se prikazati grafički i spremiti kao text file.
