Research Focus

My main research interest focuses on developing and analyzing high-resolution proxy records of past climate and environmental variability. I specialize in oceanography and climatology and the reconstruction of high-resolution climate records from massive tropical coral colonies. The coral colonies were collected at various locations in the tropics and the changes in stable isotopes and trace elements concentrations in the coral skeleton allows for the development of spatiotemporal networks of  proxy records to decipher the changing oceanographic conditions and global climate change of the past. In order to improve future climate change projections, we need to better understand the changes of the past.

One central question in my research is the reproducibility of climate proxies from individual coral colonies of a single region, because the oceanographic and climate interpretations are only as accurate as the proxy allows.  Another important research question for me is how has our natural climate varied over various time-scales from sub-seasonal, annual, interannual (patterns of El Niño/La Niña), decadal (Pacific Decadal Oscillation), and multi-decadal.

Furthermore, the state of coral reef ecosystems across the tropics are under severe threat due to ocean acidification from anthropogenic CO2 increase in the atmosphere that is taken up by our oceans. My research has already shown the impact and impairment of marine calcifying organisms’ ability to secrete calcium carbonate skeletons, which may hinder our ability to accurately reconstruct and interpret climate proxies in the future.

My newest project, funded by the DAAD-BMBF from the "Make Our Planet Great Again" programme (#MOPGA) will investigate the changes to seawater pH in our tropical oceans prior to and since the Industrial Revolution through the analysis of boron isotopes in massive tropical corals. More information on the programme and a brief description of the project can be found in the press release here (https://www.leibniz-zmt.de/en/news-at-zmt/news/overview/oasis-project.html).

Researcher Profiles


Media and Outreach

Ocean acidification in the South Pacific

Media reported extensively about a recent study that appeared in Nature Communications. In this study, Wu and colleagues present evidence that links tropical South Pacific seawater pH to the pacing of El Niño Southern Oscillation and that ocean pH has recently been decreasing rapidly.

Project OASIS - Make Our Planet Great Again - Franco-German Research Initiative (#MOPGA)

The problems of increasing atmospheric CO2 and the impacts on our tropical oceans.

Indonesian Throughflow and the South Pacific Convergence Zone

Not all El Niños are the same with impact on the South Pacific Convergence Zone and the Indonesian Throughflow.

Pacific Decadal Oscillation and Climate Change

Media reported about a recent study that appeared in Geophysical Research Letters. In this study, the authors present evidence showing the uptake and release of upper ocean heat content over the past few hundred years in the Pacific with implications on when the so-called 'hiatus' will end with future global warming.
