Research Interests
Paleo reconstructions:
- Cenozoic research: Reconstruction of Paleogene and Neogene atmospheric CO 2 , seawater pH, temperature and salinity, climate sensitivity, and carbon cycle dynamics based on boron isotopes, stable isotopes and trace elements in calcitic foraminifera and aragonitic corals
- Ultra-high resolution seawater variability and coral bleaching evidence through time from cultured to fossil tropical corals
- Common Era research: Arctic ocean acidification, freshwater input and temperature change with the use of coralline algal chemistry
- Quaternary research: Reconstruction of surface-to-deep seawater pH, nutrient and carbonate ion concentrations using cold-water corals and foraminifera: focus on high latitudes
Analytical / Development of geochemical tools for Paleoceanography:
- Proxy development in marine carbonates (foraminifera, corals, coralline algae)
- Analytical methods for micro-analyses
- Automation methods for boron purification and analysis
- Standardization of protocols for B-isotope/pH and atmospheric CO2 reconstructions and trace element analyses
Biochemistry:
- Biomineralization of corals, with focus on mechanisms of [H+] modulation and response to ocean acidification, temperature and nutrient loading
- Environmental thresholds for cold water coral proliferation
- Geochemical fingerprint of coral bleaching
Current projects
- ERC CoG "HighBorG" (2024-2029, PI: Eleni Anagnostou) explore previously unknown links between Earth's orbit and variations in temperature, carbon, and sea level when atmospheric carbon dioxide (CO2) was higher than today, but similar to what is expected at the end of this century and in our near future. Specifically, HighBorG targets three distinct climatic periods: a hot Earth with high CO2 levels, 52-46 million years ago (Ma), a less studied period from 39-23 Ma, during which Antarctica was likely fully glaciated, and a colder Earth with high CO2 levels again (17-13 Ma). *hiring now!*
