Ilsa B Kuffner, Ph.D.
Ilsa Kuffner is a Research Marine Biologist at the St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida.
As a research marine biologist for the Coastal and Marine Geology Program, I investigate the causes and effects of coral reef degradation. I explore local- to global-scale stressors on reefs, and experimentally determine how environmental variables such as sea-surface temperature, water quality, seawater chemistry, nuisance macroalgae, and ocean acidification affect coral growth, the community structure of reefs, and the process of reef building. My work informs resource managers about the mechanisms causing reef degradation and how management efforts may be improved to protect and restore degraded reefs.

Coral Calcification Monitoring Stations
Don Hickey tightens a bolt on a coral calcification monitoring station. Corals are being monitored for growth and sampled for climate proxy indicators (isotopes, elemental ratios).

Coral shading experiment during a bleaching event
Here are shown a series of photographs of a rice coral (Montipora capitata) shaded with light filters during a natural “coral bleaching” event observed during anomalously high ocean temperatures in Autumn of 2004 on the island of Oʻahu, Hawaiʻi.
