Abstract	Geoinženjering je ljudska intervencija u prirodne procese kojom se nastoje ukloniti/ublažiti posljedice klimatskih promjena. Jedna od potencijalnih metoda geoinženjeringa je fertilizacija oceana željezom. Metoda uključuje dodavanje željeznih spojeva u HNLC oceanska područja gdje je rast fitoplanktona ograničen upravo tim elementom, čime se nastoji potaknuti primarna proizvodnja i biološka pumpa te posljedično smanjiti količina ugljikovog dioksida u atmosferi. U radu je definiran geoinženjering, moguća provedba te ciljevi koji se tim metodama žele ostvariti. Opisani su eksperimenti fertilizacije oceana željezom te kemijska svojstva željeza, njegova distribucija u oceanu i uloga u fitoplanktonu, bitni čimbenici koje je potrebno proučiti za uspjeh ove metode. Predstavljeni su neželjeni učinci koje fertilizacije oceana može uzrokovati, prijedlozi za poboljšanje efikasnosti metode, važnost predviđanja rizika vraćanja odvojenog CO2 u atmosferu te razvijanja pravno određenih radnih okvira koji osiguravaju da se fertilizacija oceana željezom provodi u kontroliranim uvjetima.
Abstract (english)	Geoengineering is a deliberate human intervention in the ecosystem processes in order to counteract anthropogenic climate change. Ocean iron fertilization as a potential method in geoengineering is suggested. Method is based on addition of iron compounds to HNLC oceanic regions where primary production is limited by iron, making primary production and biological pump more intense, thereby reducing the concentration of carbon dioxide in atmosphere. In this work we present the definiton of geoengineering, main goals and proposed approaches. Iron fertilization experiments are described as well as chemical properties, distribution in the ocean and role of iron in phytoplankton community, all which are important for understanding the method. Side effects and efficiency of method are described. We present importance of developing models that can predict risks of implementing the method and importance of developing acceptable framework for research on ocean iron fertilization.
