Sensor Deployment on a Research Buoy to Monitor Carbonate Chemistry in the Eastern Mediterranean
Between 27th and 31st May 2025, Dr. Li Qiu deployed two commercial sensors for measuring partial pressure of CO₂ (pCO₂) and pH on a surface research buoy, owned by the Cyprus Marine & Maritime Institute (CMMI), located in Amathus Bay, off the coast of Limassol, Cyprus.
The Mediterranean Sea is particularly vulnerable to climate change and intensive human activity, making it a critical area for ocean carbon monitoring. The aim of this deployment is to collect continuous, full-season carbonate chemistry data to improve our understanding of how these environmental stressors affect the Eastern Mediterranean.
On 30th May 2025, with support from CMMI and SignalGeneriX Ltd., Dr. Qiu installed two state-of-the-art commercial sensors:
- A CONTROS HydroC™ CO₂ sensor for pCO₂
- An AquapHOx pH sensor for high-accuracy pH measurements
This initial deployment is expected to last 5 to 6 months, after which Dr. Qiu will return to retrieve the sensors, download the data, and perform necessary maintenance. A second deployment is planned for the following half-year to ensure year-round data coverage.
These observations will contribute to the EMS FORE Project and support regional efforts to better understand and model the oceanic carbon cycle under changing environmental conditions.

German-Israeli Alliance Symposium
At December 2024, we had the honor of participating in an important scientific event in Berlin, organized and hosted by major German research foundations: the Helmholtz Association and the Max Planck Society, and supported by other German associations: the Leopoldina Academy, the Leibniz Association, and the Fraunhofer Society.
The symposium was aimed at supporting Israeli-German collaborations and showcased cutting-edge science from German-Israeli partnerships that presented their work in diverse fields including earth and life sciences, AI, astrophysics, quantum computing, and sustainability.
We were privileged to present our Helmholtz-supported project: "The Eastern Mediterranean Sea Centre – An Early-Warning Model-System for our Future Ocean." This project was selected to represent Helmholtz's sustainability initiatives and was the sole project from the University of Haifa.
Proud to represent our collaborative German-Israeli team were Dr. Martha Gledhill (GEOMAR Helmholtz Centre for Ocean Research), Prof. Yizhaq Makovski, Dr. Or Bialik, and Prof. Ilana Berman-Frank from the University of Haifa’s Charney School of Marine Sciences.
This event underscored the strength and potential of international scientific collaboration, highlighting the importance of partnerships that transcend borders and disciplines to generate excellent science, and most importantly the unwavering support from our German colleagues during these challenging times.
