Abstract
Oceanski unos antropogenog ugljičnog dioksida (CO2) mijenja kemiju morskih voda u svjetskim oceanima s posljedicama na morski život. Povišeni parcijalni tlak CO2 (pCO2) uzrokuje gomilanje zasićenja kalcijevim karbonatom u mnogim regijama, osobito u visokim geogragfskim širinama i regijama koje se presijecaju s izraženim hipoksičkim zonama. Sposobnost morskih životinja, što je najvažnije kod pteropodnih mekušaca, foraminifera i nekih bentoskih beskralješnjaka, da bi stvorili skeletne strukture od CaCO3 izravno su pod utjecajem kemije CO2 morskih voda. CO2 utječe i na fiziologiju morskih organizama, zbog kiselo-bazne (ne)ravnoteže i smanjenog transportnog kapaciteta kisika. Nekoliko studija trenutačnih razina pCO2 ometaju buduću sposobnost predviđanja utjecaja na dinamiku hranidbene mreže i ostalih procesa ekosustava. Ovdje su predstavljena nova zapažanja, pregled dostupnih podataka i identificikacija prioriteta za buduća istraživanja, zasnovanih na regijama, ekosustavima, svojtama i fiziološkim procesima za koje se vjeruje da su najosjetljiviji na zakiseljavanje oceana. Acidifikacija oceana i sinergistički utjecaji drugih antropogenih utjecaja pružaju veliki potencijal za širenje (negativnih) promjena u morskim ekosustavima.
Abstract (english)
Oceanic uptake of anthropogenic carbon dioxide (CO2) is altering the seawater chemistry of the world’s oceans with consequences for marine biota. The elevated partial pressure of CO2 (pCO2) is causing the calcium carbonate saturation horizon to shoal in many regions, particularly in high latitudes and regions that intersect with pronounced hypoxic zones. The ability of marine animals, most importantly pteropod mollusks, foraminifera, and some benthic invertebrates, to produce calcareous skeletal structures is directly affected by seawater CO2 chemistry. CO2 influences the physiology of marine organisms as well through acid-base (im)balance and reduced oxygen transport capacity. The few studies at relevant pCO2 levels impede our ability to predict future impacts on food-web dynamics and other ecosystem processes. Here we present new observations, review available data, and identify priorities for future research, based on regions, ecosystems, taxa, and physiological processes believed to be most vulnerable to ocean acidification. Ocean acidification and the synergistic impacts of other anthropogenic stressors provide great potential for widespread (of negative) changes to marine ecosystems.
