Impacts of UV radiation on corals and other organisms in the Red Sea

Project Description

UV radiation has been identified as a key abiotic stressor in the marine environment, particularly in waters characterized by high optical transparency. One such environment is the Red Sea basin that, due to consistently minimal concentrations of UV-attenuating substances, has an exceptionally high transparency to UV radiation. This optical property and the proximity of the basin to the equator means that Red Sea organisms are exposed to intense, damaging levels of UV radiation.This project will investigate the effects of UV on scleractinian corals and other organisms in the Red Sea. ​

About the
Researcher

Susana Agusti

Professor, Marine Science

Susana Agusti
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.

Desired Project Deliverables
