Professor, Rochester Institute of Technology, Croatia

Dr. Stasa Puskaric is an oceanographer (geologist) who studies sedimentation of particles and their influence on the cycling of organic matter in the ocean, inorganic-organic matter interactions within the water column, the processes involved in the formation of organic aggregates, their influence on sedimentation of particulate matter and physiology of phytoplankton extracellular release of organic matter. From 1998 he is actively involved in different activities/initiatives associated with sustainable development and anthropogenic influence on natural ecosystems. In collaboration with UNDP and Ministry of Environmental protection and physical planning he was involved in COAST (Conservation Management of Croatia’s Coastal Zone Biodiversity) project development. Other activities include construction of sustainable houses (refer to and composting public toilet facilities.
Currently teaching Environmental Science courses at RIT Croatia in Zagreb, Croatia.

Talk Synopsis & Video Recording

Studying physiological responses of phytoplankton I realized that my results can be applied in solving the problems of global warming. Understanding the causes of the formation of “marine snow” particles led to the “recipe” on how to artificially initiate the formation of these particles perfectly resembling the naturally occurring forms. The main focus of my research is on sequestration techniques for removal of the anthropogenic fraction of CO2 from the atmosphere using the potentials of the Southern Oceans by initiating and speeding up the formation and sedimentation of “marine snow”.
