Susana Agustí Requena

Principal Investigator
​Professor of Marine Science


​Professor Agusti is a biological oceanographer. Her research focuses on the ecology of photosynthetic plankton and the metabolic balance of the oceans. She has conducted research in the Arctic, Atlantic, Pacific, Indian and Southern Ocean. Now she is also studying the Red Sea.

Her present goals focus on evaluating the impact of global change in the oceans. She aims to test the vulnerability of planktonic communities to warming, as well as to other stressors associated with global change such as increased UVB radiation, persistent pollutants and ocean acidification. She also studies other related aspects, such as stressors' joint effects and the adaptation of Red Sea organisms to global change.

Research Interests

​​-Global Change effects on the oceans with emphasis on the Red Sea
-Thermal capacity of Red Sea organisms
-Phytoplankton sensitivity to oil and persistent pollutants
-Phytoplankton cell mortality and consequences for the oceans carbon cycle
-Impacts of enhanced UVB radiation on marine biota
-Interactive effects of stressors associated to global change
-Adaptation of Red Sea organisms to global change
